The full list of 2020 slot machines can be found below. I wanted to highlight the newest slots, as a way of showing the many ideas designers have these days. Some focused on licensed slots. Others look for inventive ways to help players win, such as the “1024 Ways” slot machine on the list. Progressives and fixed jackpot games are included.

For the purposes of organizing our detailed reviews of various slots games, we’ve organized this section of our site according to which companies design and manufacture which games. Slot machineproviders like IGT have been around for decades and serve both the land-based and online casino markets. Others, like Realtime Gaming, have been around for less than a decade and only serve theInternet market.

Clicking on the links to the providers’ pages will take you to the information page on that company. That page will include a list of the games that company provides. On this page, we providebrief overviews of each company, including a couple of examples of well-known games that each company produces.

We’ve done our best to make this section as comprehensive as possible, but there are literally thousands of slots games available. If we’ve left out a provider or a game that you feel is worthyof conclusion here, please use the information on our “contact us” page to let us know.

Bally Technologies is one of the oldest and best-known companies on this list. They’ve been in business since 1968, and they offer a huge range of games.

Betsoft Gaming is famous for their innovative and impressive 3D gaming products available on the Internet. We try to be as objective as possible when writing about any company on this site.Spend some time here, and you’ll see that we rarely “toot a company’s horn”, as it were. But the games from this provider are so much more impressive than anything else on the market that it’shard to not brag on them at least a little bit. They focus more on Internet gaming than land-based casino games. Some of the games from Betsoft Gaming that we especially enjoy include: AfterNight Falls, A Night in Paris, Dr. Jekyll and Mr. Hyde, Good Girl Bad Girl, and Greedy Goblins.

One of the easiest ways to categorize slot machines is by the denomination or coin size. We use the following categories:

• Free slots
• Penny slots
• Nickel slots
• Quarter slots
• Dollar slots
• High roller slots

Below we’ve listed the most common denominations along with some observations about each of them.

If you’re flat broke, free casino slots are the only kind of slot machine game you can play. You won’t find any free games in a Las Vegas casino, but if you can access the Internet—and let’sface it, these days, everyone can access the Internet—you can find a number of ways of playing for free.

Some of these free games are previews of online casinos’ games. They offer these as a marketing tool, hoping you’ll sign up to play for real money eventually.

Other free slots seem to have no such agenda. But even in the case of those games, you’re usually helping the owner of the site providing those games by giving them an audience for theiradvertisers. These advertisers might include online casinos, but they might include any other kind of merchant who wants to get in front of a lot of eyeballs.

“Penny slots” is almost a misnomer, because it’s a rare penny slot machine that you can actually play for just a penny per spin. And that’s true in Las Vegas as well as on the Internet. We wereplanning a trip to Vegas recently, and when we were considering hotels in the Downtown area, we ran across mention of a casino there which offered true penny slots. But that’s a novelty, notsomething easy to find.

The reason you can’t play for a penny per spin is simple enough. Modern penny slots feature multiple lines and often require you to bet multiple coins per line. If you’re playing a slot machinewith 25 lines at a penny per line, you’re betting 25 cents every time you spin the wheel.

Payback percentages vary based on denomination, too. With penny slots, you’re looking at around a 93% payback percentage in the most generous casinos in Las Vegas.

Nickel slots are a big step up from penny slots, but they’re still aimed more at low rollers than other games. As with penny slots, you’re looking at betting on a minimum number of lines onever spin. But since the denomination has quintupled, your bet size also quintuples. That 25 payline slot you were playing for a quarter a spin in the penny denomination now costs $1.25 perspin to play.

The payback percentages for nickel slots are pretty comparable to those for penny slots—93%, maybe 94%, and that’s at the most generous Vegas casinos.

Quarter slots are where you’re starting to get into the average gambler range. You can find 3-reel classic slot machines where you can play for a quarter a spin, although it’s more common to berequired to place a 3 unit bet per spin on these games. And of course with video slots with lots of pay-lines, you can easily wind up betting a LOT of money on a single spin.

You don’t have to be a high roller to enjoy quarter slots, but you do need more of a bankroll than a low roller usually has.

Payback percentages start to improve at this denomination, too. You can find games in Vegas with a 95% or 96% payback percentage.

Dollar slots are starting to venture into high roller territory. If you’re in the high roller slots parlor at a casino, these will be the lowest denomination games you’ll find there. As withthe other denominations, you can find games where you can bet multiple units on multiple lines, so your total bet per spin can add up quickly. But it’s also relatively easy to find dollar slotswhere you can play for a single dollar per spin.

Payback percentages improve again here, to between 96% and 97% at the best Vegas casinos. In fact, this is the denomination we recommend playing at if you want to maximize your paybackpercentage. The dollar machines are the sweet spot—any slot machine with a lower or higher denomination has a lower payback percentage. We talk more about that in the section about high rollerslots below.

We consider any slot machine game that you can play for $5 minimum to be high roller slots. So this category is broader than our other denomination categories, because it also includes gameswhere you can play for $25 or even $100 per spin.

These high roller games are easier to find at land-based casinos than at online casinos, but high rollers can usually get the action they crave at an online casino by playing games withmultiple pay-lines.

Strangely, the payback percentages actually seem to go down slightly when you switch from the dollar denomination and move up to high roller slots. You’re looking at payback percentages of 94%or 95%, even at the loosest Las Vegas casinos.
