Largest Denomination Slot Machine

| Posted on by

I’m planning to include some reviews of various gambling machines here soon, so I thought I’d start with a look at some of the slot machine manufacturers and their products. There was a time, not long ago, when such a list would be short. But with the advent of internet casinos, the list of slot machine companies grows longer every day.

You should find the right denomination of machine for you when first entering the casino. The slot machines are either in carousels or in banks all over the gaming floor of the casino. In the casino, there are slot machines that are grouped in a circular manner, these are called carousels. Usually there are more than three in the group. Slot machines may appear to be a game of luck more than anything else, as the player merely has to spin the reels in order to play. There are no in-game decisions that improve or decrease the players odds of winning. However, there are several strategies that can help give you a better chance of Continue reading Top 5 Strategies for Slot Machines. These numbers reflect the percentage of money returned on each denomination of machine and encompass all electronic machines including slots, video poker, and video keno.

Of course, depending on where you live, you might be searching for such information using a phrase like “fruit machine suppliers” or “gaming companies.” Such a list should (and does) include old slot machine brands like IGT (International Game Technologies) and internet casino software vendors like Microgaming and Playtech.

As I create more posts about related subjects, I’ll update this page with links to manufacturer-specific lists of games and reviews of their overall offerings.

I know that a lot of sites in this space try to offer as complete a resource as possible, but please remember that I’m just one guy with a blog. I don’t have an army of freelance writers working for me, and even if I did, there are so many slot machine games from so many different providers that it would be almost impossible to keep up with them all.

But if I’ve left out your favorite slot machine manufacturer, let me know in the comments, and I’ll add it to the list.

Slot Machine Manufacturers List – Updated 2020

And here’s the list of slot machine manufacturers:

1. Ainsworth Game Technology

Ainsworth Game Technology is one of the oldest companies on my list of slot machine manufacturers. They’ve been in business for 20+ years. Ainsworth is an Australian company, and if you know anything about gambling in Australia, you know how popular slots are there. They call them “pokies,” though, which is an abbreviation for “poker machines.”

And some of Ainsworth’s most recent game additions include:

  • Action Dragons
  • Big Hit Bonanza
  • Pac-Man Wild Edition

2. Amatic Industries

Amatic Industries has been in business for over a quarter of a century now. Besides slot machines, they make video lottery terminals and video roulette games. They have a huge selection of slot machine brands in their stable, too, including some of the following:

  • Games Bond (Yes, this is a “James Bond” knockoff.)
  • GrandX (A “Wheel of Fortune” lookalike.)
  • Vampires (A simple enough theme and title, no?)

3. Amaya Gaming

Amaya Gaming is defunct now. It’s part of The Stars Group, the company which owns PokerStars. I include it here under its original name because I think some online users still look for games from Amaya Gaming. They offer lots of cute games, including:

  • Barn Yard Boogie
  • Jenga
  • Street Fighter II

4. Aristocrat Gaming Technology

Aristocrat Gaming Technology is another Australian “poker machine” vendor. They’e recently gotten their hands on some major intellectual property, too, and they offer games like:

  • Batman Classic TV Series
  • The Big Bang Theory
  • Britney
  • Game of Thrones
  • Sons of Anarchy
  • The Walking Dead

Bally Technologies is now a subsidiary of SG Gaming (Scientific Games). The company has been around forever. Not only do they make slot machines, but they used to be one of the biggest pinball machine companies in the world, too. Some of their most well-known brands include:

  • James Bond
  • Monopoly
  • Willy Wonka

7. Barcrest Gaming

Barcrest Gaming–like Bally Technologies– is also now a subsidiary of SG Gaming (Scientific Games). If you’re a real slot machine aficionado, you might recognize the names of some of their games:

13. Fremantle Media

Fremantle Media is one of the more unusual listings on this page, because they don’t exactly design or manufacture slot machine games. They own several large television brands, which they aggressively promote through multiple channels–including slot machines. If you’re playing one of these slots, Fremantle Media had a lot to do with it:

  • American Idol
  • Blockbusters

27. Realtime Gaming

Realtime Gaming (RTG) is probably the biggest online casino game vendor that still serves U.S. audiences — at least the audiences that don’t live in states with legal, regulated online casinos. (There are 47 states like that.) As a result, you’ve probably never heard of most of their games unless you’re a devoted internet gambler.

My favorite of their games is It’s Good to Be Bad, but I’m old school.

Scientific Games is headquartered in Las Vegas. They own Bally now, and they own Shuffle Master. And they also own WMS Gaming. Their most well-known game is probably Monopoly slot machines.

The Final Word about Slot Machine Manufacturers

The brand names in the slot machine manufacturers category are many, but, of course, IGT (International Game Technology) towers above the rest like Walmart towers over other retail establishments. The list above gets longer when you account for the companies making online slot machine games, too.

If you have any comments about the games available from these corporations, I’d enjoy hearing them. I’m human and make mistakes, so if you leave a comment pointing one out, I’ll update this post with corrections (and probably even give you credit.)

Introduction to Choosing Slot Machines

Once a specific casino has been determined to currently be the best of any available, choosing slot machines becomes the next step towards making a profit at slots.

Remember, statistics supplied to state gaming commissions show that the odds of winning are, on average, somewhere around 90%. By assessing all available casinos, then selecting the best possible, you’ve already improved your odds of winning – perhaps by several percentage points.

Whatever your gambling goals are, we’ll talk about those in the next step Identifying Gambling Goals. For now, we need to consider choosing slot machines that will most likely improve our overall odds even more.

So, we’ve walked into our best casino to choose slot machines with the highest odds of winning we can find. How do we select a good slot machine? Most people don’t – they dive right in without much of a plan. Well, we have a plan.

Why? Because everybody says it’s all about luck. If you pick wrong, “Well,” they say, “better luck next time.” Remember, casino employees are trained to say things like that. If you’d won a jackpot instead, you can believe they would have said, “You’re lucky! I’ll see you later when you win another jackpot!”

Slot attendants have a job to do, and it most certainly isn’t to get you to leave when you should. And, it’s difficult to not to influenced by such comments. But, try not to be.

In the following sections, I’ll briefly explain the following aspects of choosing slot machines:

  • How odds are set within a slot machine
  • Choosing denomination and maximum credits based on bankroll
  • Basics of reading a slot machine’s paytable
  • A simple way to use paytables to pick the best machines, and avoid the worst

Two Separate Odds of Winning

The odds of winning for a slot machine is a limited number of settings from the manufacturer. Besides understanding limited settings are available, it may help to understand that slot machines have two odds of winning to determine:

  • If a player will or will not win anything
  • How much that win will be, i.e., the jackpot amount

Why is understanding these two types of odds significant when choosing slot machines? Because winning slot machines come in all jackpot sizes. You’re still winning if you’re getting enough small jackpots that your bankroll isn’t shrinking. Even if it is slowly depleting, the bankroll can last quite a bit longer, so that’s also a winning slot machine.

Winning many jackpots this way is bankroll cycling. It may not seem very satisfactory, but whether it does or not depends entirely on what your gambling goals are. One type of gambling goal, earning maximum complimentary gifts, is most often achieved via bankroll cycling.

Another point about setting slot machine odds is, how often they change? Of course, it depends on the age of the casino, as discussed in the previous step Assessing Casinos for Success, or if it’s been renovated lately.

In my experience, older-style casinos change their slot machine odds every 7-10 days. Newer-style casinos can change their slot machine odds whenever the machine has been idle for 15 minutes or more, without a players club card inserted or the machine temporarily locked by a slot attendant.

Matching Bankrolls to Denomination/Credits

Only you can decide how much bankroll you want to risk gambling. I highly recommend bringing only as much money you can safely afford to lose comfortably.

Bankrolls quite literally determine which slot machines you can play. But, there’s more to it than understanding a $100 bankroll lets you play a 1-credit, $100-denomination exactly once, with very, very little chance of winning.

Whatever bankroll you have limits which slot machines can be played and how much it can be played. Slot machines have denominations ($0.01, $0.25, $1, $5, $10, etc.) and the maximum credits that can be placed in a single bet.

Slot machines typically must run for a while before wins become more likely. Yes, wins can occur at the first press of a button. They can also happen within the first few bets, where casinos offer a taste. But, usually, they need to run for a while.

About 100-120 bets is the right amount to be prepared to play to determine if you’re sitting at a winning (or breakeven) slot machine. Yes, be careful initially, perhaps making as few as 20 bets, to determine if it happens to be a “bad” machine. Trust your instincts!

If it is a poorly performing machine, a “tight” slot machine, it won’t pay out anything at all. Quick decisions are necessary here, so limited betting gives a clue to its performance, yet still leaves enough to gamble with on another machine if it isn’t – assuming you stop playing it as soon as you notice it’s not performing well enough.

So, again, you determine how much bankroll you can afford to spend. Now, take that number and divide it by 120 bets. If your bankroll is $60, then that’s 50 cents per bet. In such a way, the right choice is a 2-credit, quarter-denomination slot machine. Or, a 50-credit, penny-denomination slot machine.

Always remember to play maximum credits for the highest odds of winning. Meaning, your casino may not have a 2-maximum-credit quarter or 50-maximum-credit penny machines. But, perhaps they have a 1-maximum-credit quarter or less-than-50-maximum-credits penny machines. Such slot machines would provide more than 120 bets of play, which is going in the right direction!

Reading a Slot Machine’s Paytable

Largest Denomination Slot Machine Pays Best

When choosing a slot machine to play, a crucial aspect of winning is to review its paytable before playing. Frankly, the casino industry gains an advantage over players that don’t read slot machine paytables.

Located somewhere on a slot machine is one or more tables showing the number of credits won if specific combinations of reel symbols appear in the pay line after the player makes a bet. Below is a relatively generic example of a paytable.

The figure shows reel combinations along with their jackpot depending on the number of credits bet. Paytables don’t typically explain how much credits are worth. In general, the top row is the maximum jackpot of the machine.

Not every reel combination and its associated jackpot are usually shown in a paytable. Other reel combinations not shown in the top rows are also presented in the paytable area. Slot machines with WILD symbols can represent it with a myriad of other possible reel symbols.

A final element of paytable example provided is specific information on winning reel combinations, which can include an indication of how the slot machine operates during play. The bottom row of symbol explains that that slot machine has reel symbols which will move after the reels stop momentarily.

Such additional features may not activate until the maximum credits are bet. It can sometimes be difficult, or impossible, to determine this. Most slot machines with bonus rounds will provide at least some information about it within its paytable.

Developing a habit of reviewing and studying a slot machine’s paytable can help improve your ability to judge the financial risks involved with playing that slot machine.

How to Avoid the Worst Slot Machines

The best way to improve the odds of winning via slot machine gambling is to stop making “sucker bets”. In less colorful language, avoid playing slot machines with terrible odds of winning.

First and foremost, understand when choosing slot machines that there are indeed terrible slot machines at a casino. By merely avoiding them whenever possible, on average, your long-term gambling return will improve. Each time we raise our odds like this, we’re pushing closer to achieving our gambling goals. So, let’s make sure we do that, shall we?

Calculate this “Goodness Ratio” as follows:

  1. When choosing slot machines, as discussed above, find the paytable with the denomination and maximum credits that best matches your available bankroll.
  2. Take a close look at the paytable. What is the maximum possible jackpot when maximum credits are bet?
    • If the top jackpot is displayed in currency, divide it by both the denomination of the machine and the maximum credits
    • If the top jackpot is displayed in credits, divide it by only the maximum credits

This “Goodness Ratio” tells us how worthwhile a specific slot machine is to play relative to others. By using this approach, any slot machine can be compared to any other slot machine.

Example: In the paytable above, the maximum jackpot is 2,400 credits with three maximum credits. Therefore, its Goodness Ratio is 2,400 / 3 = 800.

Repeat this calculation for slot machines of interest. While this Goodness Ratio will be similar for many slot machines, it can be startling to find “sucker bet” slot machines that might not otherwise be avoided.

Summary for Choosing Slot Machines

After a casino has been chosen, it’s time to select candidate slot machines most likely to result in a relatively high-value win. The size of your available bankroll, whatever it is, is an essential factor in this selection process. The bankroll size needs to be matched to the slot machine’s denomination and the number of maximum credits.

Here, we’ve also discussed how slot machines calculated odds twice: once to determine if you’ve won, and again to determine how much you’ve won. Another critical aspect discussed to improve a player’s performance was the basics of reading a slot machine’s paytable.

Finally, we talked about the “goodness” ratio to help select candidate slot machines and, perhaps critically important when improving our odds of winning, knowing precisely which slot machines must be avoided.
