1. Choose Winning Slots with the Highest Payouts

When you go online to play and win money at Slots, you need to know how to pick the right Slot machine games.

Most beginners start to play casino games thinking that all slots are more or less the same thing, only with different graphics.

That's a mistake.

If you want to know how to win at slots, you need a machine that pays out more than the other ones. And to know which one is an excellent Slot to play, you need to care about the Return to player (RTP) percentage.

Legitimacy of Online Casinos Offering Free SpinsYour safety and fair play are of the highest priority. https://withomg.netlify.app/tree-usa-cash-casino-online.html. We will only show you the ones that make the cut. This is how we do that. We comb through all there is to know about a casino, from its registration and ownership to its history of dealing with player issues.

The Return to Player (or RTP) is a percentage of all the wagered money that a slot pays back to its players.

It is not the amount of money you'll get back when you wager on real money Slots, and it doesn't indicate whether you have fewer chances to hit a bonus round or not — but it gives you a great indication on whether a machine pays enough for you to play on it or not.

How to Find the RTP of a Slot Machine

The quickest option is to search for it online.

Use Google, Bing, Yandex, or whichever search engine you prefer.

Many Casino news websites that publish content around casino games have entire sections dedicated to the RTP percentage of the Casino Slot games they review.

You find them on PokerNews, as well. Every review includes a section dedicated to the payout of each type of Slot with easy-to-understand info about the games with frequent payouts.

If this is your first time on our site, check some related articles like these list of games. By choosing slots with a high RTP, you'll improve your chances instantly.

Also, you check the slot itself. The RTP number is always mentioned somewhere. Usually, you find it in the settings of the slot game or the 'help' section.

So, how to pick a winning slot machine and how to use the RTP to know how much slot machines pay?

The RTP is calculated on a scale from 1 to 100. Most slots have an RTP between 92-97 per cent.

Slot Machines Tips

Always choose an online slot machine game with an RTP of 96 per cent or above. This is the best slots strategy to follow every time you play — since a high payback percentage indicates that you have a better chance to win. good option.

High RTP Slot to Play: Devil's Delight

Devil's Delight is a slot by NetEnt that's set in the underworld.

It features everything you'd associate with hell:

  • Devils
  • Soul reapers
  • Graves
  • The number 666
  • Pitchforks
  • Skeletons
  • Flames

Is anything missing from the list?

The slot also features a separate Soul Reaper Bonus Game. There, you need to guess the sins of the characters on the screen. Every time you guess the right one — you receive points that help you win more cash.

This loose video slot has five reels and 20 paylines. And despite the sinful name, Devil's Delight is generous – RTP in this game reaches 97,6 per cent!

2. Determine the Volatility of Slots

Another critical factor to consider to pick a winning slot machine is the game's volatility.

Many games and gambling news sites refer to the games' volatility as their 'variance.' If you like, you can consider this as the risk level.

The volatility of a slot machine game measures the risk involved in playing a particular slot for the real money. One of my favourite tips for playing Slots is to consider it the 'risk factor' of the game you are about to play. That's because volatility determines how you win at slots.

  • Low Volatility Slots: Your odds of winning at these slots are high, and it's easier to strike winning combinations when you spin the reels. However, you should know that low volatility Slots offer smaller wins — so your winning combinations might not be worth as much as you would like them to.
  • High Volatility Slots: The odds of winning at these games are smaller, but the wins pay more. With the right bankroll, tips for playing Slots, and strategy, these games can be a lot more rewarding.

Both options are quite popular online since people play both types. Every useful casino guide gives you plenty of choices to find the right online slots game for you — with welcome bonus codes to try them for free before you invest your money in them.

Pick the Slot machine time that feels right for you. But keep this in mind:

To play high volatility slots, you need to be patient, have enough money to invest in a lengthy online gaming session, and have read enough casino blog posts to know all the secrets of slots optimal play.

Otherwise, low volatility slots may be a better option for you.

High volatility slots are a bit riskier, too. You never know how much time and money you need to invest in hitting a lucky spin and celebrating yet another day of winning money on slots.

How to Find the Volatility of a Slot Machine Game

Casino sites don't make the variance of the games as accessible as the RTP numbers — and that's in part because they don't want to help you improve your odds.

An easy way to choose games with the right variance is to use 'Google operators and let the world's largest search engine do the work for you.

Let's see an example:

You have seen some progressive slots with random jackpots, and the Mega Moolah game caught your eye. The most effective way to find the variance of this game is to:

  1. Open www.google.com
  2. Type 'Mega Moolah' variance in the search bar
  3. Analyse the search results

Alternatively, you can explore the games and try to figure out their variance yourself. If you play the slot long enough, you should be able to see how often the game pays out and what kind of winnings you get.

If successes are rare but significant, you are onto a high volatility game. If you win often, but the wins are nerve-wracking and small, you just found a low-volatility game.

An excellent welcome bonus, a deposit bonus, and free spins are an excellent way to do this and discover the games' volatility by playing. These options help you learn more about the games and give you useful info that might help you understand how to win at slots in the long run.

High Volatility Slot to Play: King of Atlantis

King of Atlantis is a high volatility slot by IGT. The game plays on five reels and 40 paylines.

The symbols featured in this game include seashells, gold rings, gem-encrusted crowns, mermaids, dolphins, and the almighty god of the sea – Poseidon.

This high volatility slot machine doesn't have many bonus games or features (even if you bet the maximum). The only 'special feature' you get, is a round of eight free spins that activates when a trident symbol lands next to Poseidon.

Low Volatility Slot to Try: Hotline

Hotline is one of NetEnt's most popular Slots these days.

Beating the Slot requires you to travel back in time to the '80s, wear some clothes you'd not be proud of today, and use your ability to solve a police case. Somehow based on the cult TV series Miami Vice, beating the slot needs you to help two detectives to catch a jewellery thief.

The slot runs on a classic random number generator and features all the classic features NetEnt players love so much. Wilds, expanding wilds, re-spins, free spins - you name it. Also, there is a unique bonus bet where you can choose one, two, or all three reels. It increases your chances of getting Expanding Wilds.

As pay table of this slot suggests, Hotline is a low volatility game where wins are more frequent (but small in size). If this is what you are looking for, pick this slot machine, enjoy the game, and relax.

3. Don't Go with the Obvious Option

No matter how impressive an online casino is, you need to do some research before you start to spin reels on slots.

All casino sites (like all poker sites, let's face it) want your credit card and your money. They offer free spins or deposit bonus codes to get you on their platform and then have you play as much as possible. In other words, they want your money.

If you can afford to play real money on Slots, that's great, As long as the site you agree to play on and where you look for the next loose machine to try is a legitimate and regulated online casino.

Regulators like the United Kingdom Gambling Commission (UKGC), the Malta Gaming Authority (MGA) work hard to eliminate dangerous companies from the online gambling industry. Their licensing systems are your best allies to be sure to play slot machine games on legitimate sites, use audited random number generators, and pay out winnings to the players.

An important factor to consider when you want to know how to pick a winning slot machine is to see if the site you wish to register on holds a license by the UKGC and/or the MGA. Regardless of the casino bonus they offer you or the insane fixed maximum amount of free spins they promise.

You should never play online poker or pick slot machines on unlicensed casino sites.

You find a full list of all the online casinos allowed in your country on this page.

A Loose Slot to Play: Himalayas: Roof of the World

How did I find this slot? I scrolled down to the bottom of the slots page at one of my favourite online casinos. And then, I just decided to pick a Slot machine I had never seen before.

Not all games make it to online casinos' front pages — especially those that have a combination of volatility and RTP that plays in favour of the players and that come from underdog developers. And Himalayas: Roof of the World comes from Barcrest, a provider that isn't often in the spotlight.

The

Also, Himalayas: Roof of the World offers good odds of winning on slots!. The game features an RTP of 97,75 per cent, which is above average. Combine that to medium volatility — and you know how to pick a winning slot machine.

4. Make Higher Bets

Every collection of slot machines tips or casino strategies tells you that you can't win a progressive jackpot with a minimum bet. And that's correct.

Top wins are always connected to the fixed maximum bets. You can forget your dream to become a multi-millionaire with just 0.01. In slots, like in video poker, the higher the bet — the more you can win. And, at the same time, the smaller the bet..the smaller the wins.

So, yes: your bet determines how to win at slots.

Slot machine payouts are proportional to what you wager in the game. If your slot machine strategy is to play small bets, don't change it. Just don't expect to score unreasonably huge wins.

As you understand now, betting more money helps to win more on line slots..but it also put your slot machine strategy in danger and makes you risk to lose all your bankroll much faster.

That's why higher denomination slots are also riskier than lower denomination slots. People play them in the same way and following the same slot tips..but the big wins happen only on the high denomination slots, which are also the game where you can risk to lose a lot of money.

Keep in mind this, especially if you love playing slots with progressive jackpots. Jackpot slots can be costly . Many games give you access to the top wins only when you bet the maximum — and that is why a correct slot strategy and bankroll strategy are essential to winning at Slots.

Risk is always an essential factor in gambling. And you decide how risky you want to play yourself. Never play more money than you can afford to lose and never underestimate the risks of gambling addiction — even then you play fun slot machine games.

One Expensive Slot to Play with Maximum Bets: Space Wars

Space Wars is another online slot by NetEnt. This online game is based on a popular slot you can play in all the casinos in Las Vegas and Atlantic City.

When you play Space Wars for real money, you can choose to bet anywhere from 0.4 (minimum bet) to 20 (maximum bet) per spin. The currency depends on your location.

This game does not feature a progressive jackpot, so you don't really need to bet max every time you spin. Start with smaller bets and go up. You'll see the difference in payouts.

Space Wars is a fast-paced video slot with five reels, four rows, and 40 paylines. The RTP is 96,8 per cent.

5. Trust Other Players

This is one of those Slot tips that you should not apply to many other casino games. While it may be valid for video poker, it's one you should not follow if you play online poker.

But when it comes to playing Slots..yes, you can trust your fellow Slot players and look how people play.

If a slot doesn't pay, the other players will call it out. Fast.

That's why you should use the information available on every casino blog and casino sites to your advantage. Browse through forums, spend some time on Reddit, and read what Las Vegas and Atlantic City players say about each game.

You can also join Facebook groups and ask for help there. In other words, take advantage of your internet connection before the casino takes advantage of you.

A Classic Slot People Play and Love: Gonzo's Quest

Released in 2010, Gonzo's Quest still didn't let go of its place as one of the top slot machines online. That's quite an achievement, I'd say.

This popular Slot game features five reels, 20 paylines, and an adventurer (Gonzalo 'Gonzo' Pizzarro) looking for the lost city of gold.

Players love this little guy and follow his adventures. Gonzo's Quest is one of the top-rated slot machines of all time by players, casinos, and casino critics alike.

6. Avoid Branded Slots

Branded slots are fantastic to play. We can play with all our favourite heroes and spin the reels feeling part of the movies, TV series, and shows we love.

While these games are a lot of fun, branded slots are also the 'bait' a lot of online casinos use to attract us, the players.

Remember the point about 'not going for the obvious choice'? If you are a huge Game of Thrones fan, how likely is it that you would go straight for the Game of Thrones games when you see them on the list?

Very likely.

You don't need to be a psychologist, a consumed marketer, or casino operator to realise that. Fortunately, you don't need to be a hardcore gambler to know how to pick a winning slot machine either. That's what this article is for!

Developers with slots that feature popular brands paid a pretty penny to use the name. So, they won't let you go low with the bets. And those games will not be the easiest ones to beat either.

While the casino and the developer have invested a lot on the names you see on the screen, you are the one who can make it worth the investment. Or not.

Slot to Play Instead of the Branded Ones: Pamplona

What's so attractive about branded slots? Well-known name and faces. The stories behind the games and the characters we all know and love.

Can you have all that in a non-branded slot?

Take the Pamplona slot machine, for example.

This IGT slot is all about Spain, bulls, and matadors. A unique tradition turned into an exciting slot game.

In a way, it is a 'brand' because Pamplona's running of the bulls' festival is known worldwide. And it's more known than some actual brands, to be honest.

But to use this theme, developers didn't have to pay as they do for the brands. Thus, the payouts are way better.

The slot has five reels and 1024 paylines. Matador symbol acts as a Wild and Bull is a Scatter. Three scatters can trigger the El Toro Bonus where you can choose your option of Free Spins.

7. Take Advantage of Free Spins

How to win at slots with free spins when there are hundreds of hidden terms and conditions for withdrawals?

The wagering requirements can take the fun out of playing slots with free spins. No arguing there. But there are still free spins bonuses that can be worth your while.

The wager-free bonus offers.

On a limited number of online casinos you get wager free spins with no deposit on registration (yes, no deposit is required to play). And with no strings attached to them.

There is no cap on winnings, you can cash out anything you want, anytime you want, and there are no wagering requirements. How good is that?

Slot to Play with Free Spins: Pyramid Quest For Immortality

From Pamplona to Egypt. You can travel the world with slots..and the right free spins welcome bonus!

The Pyramid: Quest for Immortality slot features five reels, 720 paylines, and an RTP of 96.4%. This game takes you to ancient Egypt and brings you to explore the hidden and mystical world of Pharaohs, Gods..and pyramids, of course.

So, how to beat slot machines?

First and foremost, the best way to beat the Slots is not to continue asking the wrong questions and stop looking for simple hacks or Slots tips tho beat the casino.

If you want better odds to win on Slots, you need to:

  1. Choose the slots that have high payouts
  2. Choose the slots with the correct volatility level
  3. Choose the slot with the highest Return to Player
  4. Read reviews of the Slots on casino sites, forum, and Reddit
  5. Sign up to get a bonus with low wagering requirements
  6. Play on a licensed online casino site

While this might not be enough for you to beat slot machines and pick the winning Slot machine every time you play, it will help you win more often and - more importantly - enjoy playing Slots a lot more!

FAQ

How do you pick a winning slot machine?

To pick a winning slot machine and get better odds to win when you spin the reels, you need to choose games that offer the right combination of betting limits, volatility, Return-to-Player, and wagering requirements (in case you play with a bonus).

What casino game has the best chance of winning?

In general, Blackjack is the casino game with the best odds. In terms of slots, the best choice is to pick a game that offers a return-to-player over 97% like the Slot Devil's Delight (RTP: 97.7%).

Are slot machines rigged?

The slot machines you find on regulated casino sites are not rigged as their Random Number Generator (RNG) is subject to frequent audits by state-owned gambling authorities. The same controls do not apply to unlicensed casinos — and that's why you should never play your games there.

Introduction to Controls Slot Machine Odds

Who controls slot machine odds is a popular question from slots enthusiasts. It’s quite an interesting question, which I thought my audience would appreciate an answer to.

My most recent encounter with this general question was during the Q&A segment of another gambling podcast, episode #634 from Five Hundy By Midnight. They had a question from David which was, “When a new themed penny slot debuts, what is the typical hold percentage? Does it vary by machine, casino, or both?”

Tim and Michelle, co-hosts of the long-lasting Five Hundy By Midnight, a gambling podcast that’s all about Las Vegas, answered the question well, if somewhat briefly.

I’m sure my own audience would like the answer too, so I’m providing a few more details as well as a more general answer with a bit of the why of it all.

This segment has the following sections:

  • Introduction
  • A Bit of Background on Legal Requirements
  • A Bit of History on Physically Setting Odds
  • Slot Machine Types Based on How Odds are Set
  • Identifying Who Controls Slot Machine Odds
  • Does It Really Matter Who Controls Slot Machine Odds? Yes!!

The Green Machine Slot Odds

A Bit of Background on Legal Requirements

To answer this question, I’ll need to delve into a bit of recent history to explain how odds are set in older-style standalone slot machines using a random number generator (RNG). This way is how many people incorrectly believe the odds are currently set on ALL slot machines.

However, starting around 2008, a lot changed with setting slot machine odds. These changes are due to the emergence of new gaming technologies, not only in slot machines but also with the development of casino operating software. Both provide casinos with an increased operating efficiency and therefore low operating costs.

With so many more people visiting casinos in the last decade, and with their profit margins getting smaller every year, casino operators find they cannot afford to ignore the savings opportunities of new technologies.

The second driver for this change to how slot machines are controlled is due to ongoing developments in statutory regulations for gaming jurisdictions. In the U.S., these gaming jurisdictions are the states, territories, or federal district that legally allow gaming.

In essence, casino operators have to follow the gaming regulations for the jurisdiction wherein they are located. In part, these gaming jurisdictions often include laws which place an upper and lower limit on the pay back return for slot machines.

To not lose their gaming license, or to otherwise get in trouble with gaming control authorities, casino operators must remain in compliance with these legal gaming requirements.

Note that commercial casinos have to be comply to gaming regulations as set by the U.S. state, territory, or federal district they are located in. Native American tribal casinos also have to comply with their own set of gaming requirements, which are usually not based on state law.

Rather, these are defined by negotiation between a federally-recognized tribe and the state within which they are located by carefully crafting a state-tribal compact ultimately approved by the U.S. Department of the Interior.

So, within this overall context, who controls slot machine odds? At a high level, gaming regulators determine the legal limits, if any, for payout returns on slot machines. This is accomplished via state law or negotiated compacts, and usually not changed for a decade, if that often.

Casinos operators are, often but not always, required to provide weekly or monthly reports on actual payout returns to show their gaming authority they are compliant. Sometimes, depending on each gaming jurisdiction, these statistical reports are then provided to the public by the state gaming commission.

Going further, these regular reports can break down these actual payout returns by casino, table games, slot machines, gaming machines, by the denomination of slot machines within a specific casino, or even if the machine has a progressive jackpot. What is done is very specific to the gaming jurisdiction where the casino is located.

Given all these variability of what is or is not done within a U.S. gaming jurisdiction, I’ve created an online series of posts for my audience of slots enthusiasts. It’s meant to help them navigate this dynamic environment of state-specific gaming regulations.

For more information on your specific state, territory, or federal district of interest, see Slot Machine Casino Gambling, State-By-State: A Weekly Blog.

So, at its high level, slot machines are controlled by gaming regulators by the placement of legal requirements for payout return percentages. Sometimes, however, these state-specific gaming regulators do not set limits on payout returns. Put another way, they have deliberately chosen to not set legal limits.

When this happens, somewhat obviously, casino operators do not have a legal requirement for setting payout returns. However, to remain open and not close due to lack of customers, they still have to be careful to not set their payout returns too low.

It’s worth noting that most gaming regulations set a low limit on payout returns to which casino operators deliberately stay well above. To do so is just good business.

A Bit of History on Physically Setting Odds

The random number generator (RNG) was developed for slot machines by Bally Technologies in 1984. About a decade later, most slot machines had this RNG, which allowed for easily adjustable odds of winning.

Beforehand, the odds of winning were set in an entirely mechanical manner. This worked well for decades, until the technical development of slot machines began to cause difficulties. Basically, as credits to bet and number of pay lines increased, the physical mechanisms for determining odds began to reach certain physical limits.

Slot enthusiasts loved having a choice of how many credits to bet, as well as playing a slot machine with more than one pay line. Increased credits and pay lines also led to much higher jackpots.

All of these developments led to odds of winning being needed for many more possible outcomes, which mechanical devices for determining the odds of winning began to not be able to handle. In fact, these mechanical devices began to fall behind and actually became less and less random in nature.

As an aside, the topic of randomness is actually quite interesting. True randomness is very difficult, if not literally impossible, to generate. Often, when randomness is needed in either an mechanical or electronic device, various methods are used which are “random enough.”

Technically speaking, there is no such thing as an existing perfectly random number generator. At best, there are only pseudo random number generators, one variant of which was patented by Bally Technologies in 1984.

Moving away from our brief sortie into the philosophy of randomness, the invention of the RNG solved for slot machine manufacturers this limitation of mechanical devices for determining randomness in slot machines. But, it created another problem: With adjustable odds of winning via electronic RNGs, casinos would need to have a large workforce to do that adjusting. https://withomg.netlify.app/more-slots-games-for-free.html.

And so, that is what casinos did. They built and trained a workforce of slot mechanics to adjust the odds of winning on their new slot machines to meet their desired performance metrics.

However, the size of that workforce would increase tremendously depending on how often those odds of winning were adjusted. For older style slot machines, this is at least 7 days and may be as much as 2 weeks, as I’ve expressed in Professor Slots Episode #21: Winning at Slots on Older Casinos-Kentucky Slots 2018.

Most recently, since 2012 or so, relatively newer casinos have been able to reduce this costly workforce thanks to new casino operating systems. These systems not only help casinos manage large promotional events with less overall issues, but also allow them to remotely adjust the odds of winning on slot machines connected to the casino’s central computer system.

Of course, this connection to the casino’s central computer system is currently limited to a wired connection due to potential security concerns as well as WIFI bandwidth limits. As a result, using a central computer in this manner is only possible if all the slot machines are physically “wired up.”

Doing so requires sufficient building infrastructure, such as clearance beneath floors and behind walls, to allow for these many, many cable connections. This is only practically possible in all new casinos being built as well as older casinos being heavily renovated. That is to say, renovated to have far more than simply new carpeting and wallpaper.

With wired connections from slot machines to a central computer, the reduced cost of a smaller workforce of slot mechanics, much faster adjustment of casino performance metrics to daily or even hourly updates, and more satisfied customers due to efficiently run events, the question remains. Who controls slot machine odds?

To get closer to the answer to this question, we’ll next have to discuss how the legal limits of payout returns are set on actual slot machines. Why? Because slot machines can be categorized by how their odds are set. And, how those odds are physically set will tell us who really controls them.

Slot Machine Types Based on How Odds are Set

Slot machines can be divided up into methods by which their odds of winning are set. These slot machine types include:

  • Standalone
  • Casino-Specific Progressives
  • Multi-Casino Progressives
  • State-Wide Progressives
  • Remotely Controlled Onsite by Casino
  • Remotely Controlled Offsite by Gaming Regulators

Standalone slot machines are those which are most often found in older casinos, but are technically slot machines including within their cabinets the ability to set and provide odds of winning with a random number generator. A workforce of slot mechanics adjust the odds of winning periodically as directed by the casino operator.

In general, there is a limited number of settings available for these older slot machines. YouTube videos are available from individuals who have personally purchased an older style, standalone slot machine showing exactly how these odds are set.

For those videos I have viewed, there were six possible settings which could be entered after opening up the slot machine door. These settings were based on codes from a booklet provided by the slot machine manufacturer.

Keep in mind that videos such as these are the general source of knowledge most people have about the internal workings of slot machines. Employees of slot machine manufacturers and casinos with access to these payout settings simply aren’t sharing this information due to non-disclosure agreements and other legal restrictions.

What Slots Have Best Odds

Besides which, accessing the control for changing the odds of a slot machine is quite problematic. The slot machine is alarmed, so any tampering without official access (employee card key, entry code, physical key) are required to even open a slot machine door. Not to mention, the casino surveillance system sees all.

Discussing the three types of Progressive Slot Machines mentioned will be the dedicated topic for another time. I’d discuss how the ownership of these Progressive slot machines matters with regards to how the odds of winning are set. Briefly, the amount of the Progressive jackpot is primarily based on how many slot machines are included.

For instance, these can be a carousel of slot machines in a certain area of a casino, it can be a larger number of slot machines located throughout a casino, or a large group of Progressive slot machines located at multiple casinos.

These large group could actually be of two types: multiple properties of the same casino operator, or multiple casino operators, within a single gaming jurisdiction, i.e., state.

Already discussed are slot machines remotely controlled onsite at a casino through the use of a central computer operating system. Only new or heavily renovated casinos have the facility infrastructure to handle the sheer number of cables necessary.

If they are controlled onsite, these slot machines have their odds of winning adjusted daily or hourly by remote access. How often these adjustments are made is, rather unfortunately at this time, a matter of debate.

I’m currently trying to track down state legal requirements of which I’d heard rumors. The rumor I heard was that a slot machine must be idle for at least 15 minutes without a players card being inserted before the casino is allowed, if desired, to remotely adjust its odds of winning. Further, the rumor stated that this practice was typical and originally based on Nevada gaming regulations.

However, this rumor doesn’t pass the so-called smell test. At this time, I’ve currently reviewed state gaming regulations for over 38 U.S. states, territories, or a federal district. I’ve yet to find any substantiation for this rumor. Alternatively, it may well be an accepted business practice built-in to the advanced casino operating systems.

Why do I feel strongly that slots players are protected from having their odds of winnings reduced while playing? It’s simple – the state control board controls the odds of winning on slot machines, and everything I’ve seen, read, and studied tells me they work for you.

I just can’t imagine state gaming commissions would allow something this untoward, this nefarious even, to occur. They have careful casino operating system approval processes in place to prevent it, they watch casino operations like hawks (often from within the casino), and any casino that decides not to be fully compliant is in for a world of hurt if/when caught.

Finally, there are slot machines having their odds controlled off-site by state gaming regulators. These are most or all video lottery terminals style slot machines.

Video lottery terminals are, as their name implies, instant lottery machines. That means they are controlled by the state lottery, which is set up to remotely handle many, many such terminals at any given moment.

Identifying Who Controls Slot Machine Odds

Who controls slot machine odds at a casino you are considering whether or not to visit? Who controls slot machine odds on the slot machine you’re sitting at?

As I’ve discussed before, both on my webpage Assessing Casinos as well as Professor Slots podcast episode #3: Assessing Casinos, Alaska Slots 2017, deciding which local casino you want to spend your time at is an important decision for determining your baseline success at slots.

So, you’ll likely want to know who controls slot machine odds when you’re choosing between, for instance, an older, pre-2012 casino with standalone slot machines or a racino with many new video slot machines.

The top level choice is really about your own gambling goals, as also discussed on my webpage Identifying Gambling Goals or, alternatively, within Professor Slots podcast episode #5: Identifying Gambling Goals, Arizona Slots 2017.

But, whether your gambling goal is entertainment, earning maximum comps, or take-home money, having better odds of winning on a slot machine will help accomplish that goal. So, ignoring other important considerations such as drive time, the spread of the buffet, players club, and etc., the type of slot machine is definitely a consideration.

Casinos with standalone slot machines where the actual machine in front of you has its own dedicated random number generator is relatively easily determined. Ask someone, how old is the casino?

Or, if you don’t want to ask someone or look it up online, just take a look at the slot machine in front of you. Specifically, look at the player card interface area. What does its display look like? Is it a touchscreen display?

Or an LED display like those seen outside of a bank showing the time and temperature for a passerby to see? If it’s a touchscreen, the slot machine is most likely not standalone. If it’s an LED, it most likely is a standalone slot machine.

Determining whether or not a Progressive slot machine is connected to a single carousel, across several carousels within a casino, across several casinos owned by a single casino operator, or across several casino operator properties will be, as previously mentioned, the topic of an upcoming post.

Next up are non-video slot machines with touchscreens at the players card interface. These are all slot machines centrally controlled by a computer onsite at the casino. You can confirm this by learning the date of the casino’s original opening or when it was last heavily renovated.

Keep in mind that a very few casinos have both, assuming they have expanded their original structure not by renovating it, but by building a new casino facility right next to it.

This is the case with Foxwoods Resort, which is itself an older style casino. However, they recently build Fox Tower right next to it, which is a newer style casino.

Finally, there are video slot machines. It can be difficult, if not impossible, to tell the difference between a video slot machine and a video lottery terminal. A video slot machine is controlled onsite by the central computer at the casino. A video lottery terminal is controlled offsite by the state lottery.

The only sure way to tell the difference between these two slot machine types is to take a look at what the state gaming commission says they are at that casino.

For instance, in Ohio, there are currently 4 commercial casino resorts and 7 pari-mutual racinos. The 4 casinos have traditional reel and video slot machines all controlled by a central computer located onsite.

However, Ohio’s seven racinos have a mix of traditional reel and video lottery terminals slot machines. The traditional reel slot machines are controlled onsite with a central computer while all of the video lottery terminals, which externally look exactly like video slot machines, are controlled offsite by the state lottery’s central computer systems.

Does It Really Matter Who Controls Slot Machine Odds? Yes!!

With this improved understanding of how casinos work, let’s consider these two facts. First, that there are types of slot machines, specifically those that are standalone or remotely controlled by casino operator or state. Second, that there are the several ways slot machines can have their odds of winning set on an ongoing basis, depending on their specific type.

So yes, actually, it does matter who controls slot machine odds. Why? Because this is where patterns of winning are found. When slot machines are set up to be as random as possible, and that assigned level of randomness is unchanged over days and weeks, then long-term statistical principles rule.

Meaning, on average over the long haul, people will always loss money playing slots. Put another way, profits are only possible in the short term. This specifically applies to all slot machines controlled by the state, such as video lottery terminals.

However, when the odds are changed hourly or set over 100% for promotional purposes, then there are better times to play a slot machine – and all that slot enthusiasts need do is figure out when that better time is in order to win more and, potentially, make some level of profit. That’s what I did: I made a profit at slots by looking for and finding winning patterns, when I won 90 taxable jackpots in 9 months.

Only casino operators change their odds hourly or deliberately adjust them for promotional purposes. The state has no need or desire to do so, getting their money no matter what, while the casino is a business, with stockholders and a board of directors, obligated to try to succeed financially.

The casino puts in the time and energy to hit their financial performance metrics. The casinos hire the best general manager who themselves hire the best possible team.

Put another way, the casino has a business need to adjust the odds of winning on their slot machines to eke out a living while the state only needs to be patient. Businesses are not patient – they try things in their ongoing quest for success.

And, really, that struggle is what has changed since around 2012 with the technology behind the winning odds of slot machines. Casinos are always trying new things. And, when they have control over setting the odds on slot machines, they adjust them to try to succeed.

Before 2012, this amounted to increasing the odds of winning to be over 100% on a single slot machine near a busy area in their casino, as a promotional tool with its own limited budget.

With the new casino operating technologies, casinos have been given a finer control over setting those odds. This has allowed them to try new things, which they very much like to do. These new things are to adjust the odds on slot machines more often than ever before.

In financial terms, they’re trying to tune their financial performance metrics on a daily or even hourly basis, something that was never before possible.

I’ve never worked for a casino, so have never been pitched a new casino operating system by a slot machine manufacturer’s sales team. But, it’s obvious that this “tuning” is part of the pitch being made to casino operators. Without having seen it, how can I believe this? Simple. I’ve won a lot at slots through pattern recognition.

What’s happened is that, and it matters not at all how it came about, casinos have obviously bought into the idea of finely tuning their financial performance metrics.

In the case of slot machines, which is the only game as casino offers that I’m interested in, they’ve broken the long-term constant randomness of the odds of winning on a slot machine. Therefore, as all statisticians know, patterns emerge.

So, again, yes it does matter who controls slot machine odds, because those controlled by the casino have had their randomness broken. It matters because slots enthusiasts can look for emerging patterns on these casino-controlled machines, then use them to win more.

In the future, I’ll talk more about the winning patterns I’ve found using this understanding. In the meantime, I hope I’ve made it clear how and why they exist.

Summary of Can You Guess Who Controls Slot Machine Odds?

In summary, who controls slot machine odds is answered by understanding they are controlled by the machine, the casino staff, both, possibly the state if the machine is a video lottery terminal, and by slot machine manufacturers themselves in the case of most Progressive slot machines.

This control over the odds of winning was historically a mechanical device supplanted by an electronic random number generator invented in 1984, afterwards allowing slots machines to be developed having more credits, denominations, and pay lines as well as higher jackpots.

There’s currently older-style casinos with standalone slot machines and newer-style casinos built to have the facility infrastructure necessary for physically wiring up their slot machines to be remotely controlled by a computer server.

I’ve discussed how to tell the difference, as well as explained how slot machines can be remotely controlled by the casino or, in the case of video lottery terminals, by computers established for this purpose by the state lottery agency.

Finally, I’ve discussed if any of this matters to slots enthusiasts looking for an advantage. It does matter. In essence, any slot machines with odds of winning directly controlled by a casino have patterns of winning because casinos keep adjusting those odds to meet their financial performance metrics.

These patterns make it possible for savvy slots enthusiasts to improve their own gambling performance.
