Slots were one of the first types of casino games that started accepting Bitcoin and they are one of the most popular offers at any Bitcoin casino today.

Due to the ease of producing slots, but also their popularity in any casino, land-based or online, slots have grown to outnumber any other casino game by far, and thus offer a diversity that can’t be found in any other game menu.

Although slot sites existed since 2011, one of the first big casino software providers to start offering Bitcoin slots were SoftSwiss, who released a line of their popular 3D video slot games around 2014 that accepted the cryptocurrency.

Luckily, other casino game makers quickly followed suite, so today you will be able to find even names like BetSoft, NetEnt, iSoftBet or Pragmatic Play, among the list of providers powering online Bitcoin slot offers.

Thus, there really isn’t a better time to be a fan of both Bitcoin and slots than today, as you’ll likely find dozens of different types of slots in your Bitcoin casino, with almost any feature or theme you can think off. But before you do, you might want to check out our Bitcoin slot guide below, to make sure you understand the basics concepts behind slot games before you spend any money.

Types of Bitcoin Slots

If you’ve ever given online slots a try, you’ll know what exactly to expect from Bitcoin slots as well. Since most of the games offered are the same games you can also find in casinos that don’t accept Bitcoin, there’s little difference in terms of variety between Bitcoin and regular slots. In short, you’ll have no problem finding all or most of the following types of slot games:

Classic Slots – Classic slots are, sort to speak, simulations of the old mechanical slots that predated modern slot machines. Thus, by classic slots, most casinos mean retro, Vegas-styled 3-reels games with simple payouts, rules and, most often, just a single payline.

3D/ Video Slots – Video Slots are actually the modern types of slot games you expect to find when you visit a casino today. Video slots are normally 5-reels games with advanced graphics, animations, and sound effects, but also multiple paylines and extra features like free spins, bonus rounds, etc. Some even have separate game rounds given as a bonus where you have to “game” to win some prizes.

Licensed Slots – Licensed slots are one of the most popular types of modern Bitcoin slot games. Basically, these are modern video slots with themes borrowed from licensed franchises like popular movies, TV shows, celebrities, or even game shows and board games. The “licensed” part applies to the game manufacturer having to sign a deal with the copyright owner to use visuals/audio from the franchise. Some of the most notable examples include Game of Thrones, Man of Steel, and Guns N’ Roses.

Progressive/Jackpot Slots – Progressive slots are slots that have a progressive jackpot. A progressive jackpot is a jackpot pool that’s filled by multiple users, which in the online world means dozens or thousands of users at a time. Depending on whether they are local progressives (casino only) or global, these slots can offer anywhere from small cash prizes to life-changing jackpots.

Low/High Denomination Slots – Another popular slot classification is categorizing games by low/high denomination. Low denomination games, or penny slots, as they are also called, can be played for small sums of money and smaller rewards. High denomination games are the opposite and they allow plenty of money to be wagered on each spin.

Playing Bitcoin Slots – What You Need to Know

Playing Bitcoin SlotsIf you’re a rookie slot player, or just someone who hasn’t had that much experience with this type of casino game, you should definitely get to know some of the basics of playing slots online. To keep things short, the following features are the key things you need to understand if you want to have the best experience.

How Paylines Work – Paylines are basically different ways to win at a slot game. Old slots had only one payline – the horizontal line that stretches across the middle of all 3 reels. If you landed 3 identical symbols on the same line, you’d win a prize. Well, most modern slots have anywhere from 5 to 243 paylines stretching horizontally, vertically, zig zag, or in any way possible to allow for hundreds of different ways to win.

However, the trick is that all those paylines will not be activated if you don’t pay for them. Most slots come with a control feature that allows you to activate groups of paylines by increasing your wagers, which is why it’s always good to check out the info table on any game you play.

And remember, the cost of each spin is calculated by multiplying your bet with the number of paylines/levels, so a bet of 0.01 BTC on 20 paylines will actually cost you 0.2 BTC per spin, and so on.

RTP (Return to Player Percentage) – A slot game’s RTP is basically the payout rate of the game. Most slots will have an RTP of around 96%. To give you an idea of what RTP is about, a 96% RTP theoretically means that if you bet 0.1 BTC on 100 spins in a row, you can expect to lose 0.4 BTC during your 100 rolls. Of course, this is a theoretical calculation, but, in general – the higher the RTP, the better the slot.

Provably Fair – Most Bitcoin slots now have a provably fair feature, which you can use to check whether the game’s outcome is truly random. The way the feature works is by giving you a “hash number” which you can copy and then play out the spin. If the resulting number sequence matches your original hash number, it means the casino didn’t interfere with the outcome. To find the checking system, you’ll have to browse through the game’s menu.

Paytables – And finally, you need to understand what paytables are. Every game comes with a pre-defined list of different symbol combinations and the payouts they generate. In this list, you can learn what combinations trigger the jackpot or even how many times your wager will the slot pay out with a combination of 3 lowest paying symbols.

How to Play Bitcoin Slots?

Slots aren’t games of skill or advanced strategies like Blackjack and Poker are, so playing them is very easy. The first step would be to register with a casino and load some money into your account. Once you get that out of the way, it’s all about following a few simple steps:

  1. Check the RTP – Usually disclosed in the game info menu or on a separate page at the casino.
  2. Check the Paytable – See what different combinations pay out.
  3. Check the Bonus features – See if there are any free spins, multipliers, or extras that can give you higher wins.
  4. Adjust your bet size and level/paylines – Choose how many paylines you want to bet on and how much you want to bet on each line.
  5. Set up auto mode, if you want – You can also automatically adjust your slot to play out a number of spins per your defined wager.
  6. Spin!


Can I Play Bitcoin Slots for Free?

Yes, most casinos offer demo version of the games. You can use these demos to test out each slot, learn its features and payouts and see if you like to spend money on them.

Are There Really Cold/Hot Slots?

Slots use Random Number Generator (RNG) software that ensures each spin stays entirely random. Even if a game paid out several times in a row, this doesn’t mean it will continue to do so once you sit behind it.

Are Bitcoin Slots Fair?

A lot of Bitcoin casinos offer RNG certificates from third party auditors or a “provably fair” feature to allow you to test the randomness. In short, you can check out whether the games are really fair or not by yourself, in most cases.

Do I Have to Make Big Bets to Win a Jackpot?

Not necessarily. Some of the biggest jackpots have been triggered on very small bets. But in games where paytables are based on your exact bet per each spin, bigger wagers will lead to bigger prizes. That’s why it’s always good to check out the instructions and paytables before you play.

Can You Cheat Slot Games?

No, you can’t’. Bitcoin slots are digital and based on RNG software which cannot be “tricked” by anything you do in the game.


Slots have always been one of the most played casino games and to no surprise. Their biggest advantage is that they are very easy to understand and cheap to play, but also quite entertaining thanks to the incredible efforts slot producers have invested over the years in improving their games. And when you add big cash prizes and Bitcoin’s anonymity to the picture, there’s really little to complain about. That is, apart from the fact that playing slots means betting on nothing else but your luck, but that’s the case with most casino games.
