Bitcoin is a type of cryptocurrency, a brand-new form of online payment that is fast and relatively simple to use. One of the main advantages of cryptocurrency like Bitcoin over other payment methods is the fact that it’s decentralised and usually trustless. This means that you don’t have to worry about entering your payment details online and all transactions are recorded on something called the blockchain.
The blockchain can’t be edited, and all of the transactions recorded on it can be publicly looked up and verified. This makes it ideal for payments, and many online casinos are starting to accept it. Blockchain technology also has other uses such as powering the games themselves. Casino games built on the blockchain are provably fair, giving players more reason to trust them.
Here at Xfire, we love playing casino games and have a lot of appreciation for well made video slots. These days, there is so much variety when it comes to slots, and we’re a long way from the traditional fruit machine games of years gone by. Bitcoin slots are one such way in which technology has helped to improve how people play slots.
In this guide, we’ll be going over some of the most popular Bitcoin slots that you can find online, including how to play and our honest review of each game. We’ll also give you some details on what makes Bitcoin slots so special and whether there’s anything you need to look out for to land those big payouts.

The History of Slots
Slot machines, sometimes colloquially known as fruit machines, slots, pokies or one armed bandits, have a long history. The first gambling machine was developed in New York back in 1891. Gambling, usually with cards, was a popular pastime in saloons and bars across the United States.
This first gambling machine used playing cards which spun on five drums when the player inserted a coin and pulled the lever. The aim of the game was to land a good Poker hand, and while there was no direct payout mechanism, players would collect their prizes from the owner of the bar. Odds were changed in the house’s favour by removing two cards from the deck, doubling the odds of landing a royal flush. The machine proved to be a highly popular invention, and soon the machines could be found across the country.
Because this early slot game had a large number of possible winning combinations, it was difficult for early inventors to create an automatic payout system. Instead, mechanic Charles Fey came up with a simpler game. Between 1887 and 1895, Fey developed a machine that contained three spinning reels and five symbols, diamonds, horseshoes, spades, hearts and the liberty bell. The machine became known as the Liberty Bell and has inspired countless other slot machines since then.
In 1976, the first ever video slot was created. This new breed of slot machines used video screens to display animations and graphics and used computer programming for truly randomised payouts. These new machines led to the popularity of slots increasing, and soon developers were adding new bonus features, special rounds and other exciting features to make them more fun to play. With no mechanical constraints, modern video slots are able to use larger numbers of reels, symbols and bonus features than their predecessors. Today, slots are only limited by the imaginations of their developers, and players are able to enjoy some truly spectacular games.
What Does Provably Fair Mean?
One of the most important aspects of online gambling is trust. A player must be able to trust the casino and the game that they’re playing and hope that it hasn’t been tampered with to give an unfair advantage to the casino. Gambling authorities have helped to bring peace of mind to players by issuing gambling licences to tested casinos and auditing games for fairness. Still though, it can be hard for some players to trust that the casino isn’t just out to take their money.
With provably fair games, players don’t have to rely on trust. Instead, they’re able to look up and verify for themselves that the games they’re playing are based on random chance and fair to play. All casino games should use a random number generator to determine the outcome of the game. Whether it’s a slot or a table game, random chance is what makes gambling fair to the player.
A provably fair gambling game, such as one built using the blockchain, will display the algorithm that’s used for hashing and random number generation. Players can look this up and test them for themselves to see that they are accurate and fair. This system means that third party verification and auditing is no longer necessary and removes the need for a player to blindly trust the casino and licencing body.
Different Types of Slots
These days, there are loads of different types of slots available to play online. With so many different software developers out there, the range of game for players to try out has never been better. Before you jump in and start spinning, it’s a good idea to familiarise yourself with the main types of slots you’ll come across. Below are some of the most common types of slots and some key details of each one.
Classic slots tend to be the most straightforward type of online slot game and usually follow a similar style to the early slot machines and fruit machines. Typically, they’ll use three reels and three rows, usually with only a few different paylines available. Most classic slots don’t have bonus features such as scatters or wilds, but you might find these included in some of the more modern, classic-style slots. If you’re new to slots, these are great to check out because they’re easy to get into and you can still have loads of fun.
Video slots utilise the latest technology to give players the most exhilarating experience. These games typically combine high-quality animations, graphics and music to create immersive and fun to play games. Most modern slots are examples of video slots, and these games will usually use a five reel format. Video slots tend to also feature lots of bonuses and special symbols such as scatters and wilds that can increase the player’s chance of winning big prizes. Most slots you’ll find at online casinos will be video slots, and there are loads of great developers out there which focus on producing them.
Jackpot slots give players the chance to win potentially massive prizes. While most slots can sometimes payout big, jackpot slots will have several top prizes available for players to win. These will usually have a very small chance of triggering, and there will normally be three or more jackpots of different sizes available. Some jackpot slots use a progressive jackpot system, where the jackpot builds up over time as more players bet on the slot. Others use fixed jackpots, which will be the player’s stake multiplied by a certain number that doesn’t change. Progressive jackpots tend to be the biggest paying casino games, some of which payout millions of dollars to lucky players.
Bitcoin slots are the latest innovation in the world of casino gaming. These slots use the blockchain to create a provably fair game that is based entirely on luck. Bitcoin slots tend to be a mix of video and classic slots. Usually, they’ll utilise five reels and bonus features but normally with fewer animations and graphics. Some Bitcoin games will offer jackpots, but the vast majority gave fixed payouts based on the paytable and symbols they feature. If you want to play fair and trustable games, Bitcoin slots are a great option. Most Bitcoin slots will typically have a lower house edge of between 1 and 3%. This is a lot lower than the standard of between 4 and 6% for most slot games.
The Best Bitcoin Slots
Bitcoin and the blockchain are still relatively new technologies having only first been developed in 2009. Still though, the number of Bitcoin slots being developed is growing as more players are releasing the value of playing with Bitcoin and the verifiable nature of the blockchain.

How to Win Big with Bitcoin Slots
Slots are based on random chance, and if you want to win big, you’ll need to get lucky. However, there are still steps you can take to improve your chances of winning and help you land that big jackpot you’ve been dreaming about.
At Xfire, we play a lot of slots, and we’ve learned a thing or two over the years about how they work and the best ways to improve your winning chances. Take a look at some of our tips below. Remember to always play responsibly and never bet what you can’t afford to lose. These tips won’t guarantee you wins, but they will help you to make the most out of your time playing slots.
Play at a trusted site – There are hundreds of online casinos out there, but not all of them are as good or safe to use as others. If you want to gamble online, it’s important to make sure that the site you use is trustworthy and isn’t going to give you issues when it comes to withdrawing your money. Always make sure that any casino you play at holds a licence from a reputable gambling authority. This licence will also depend on where you live, as not every casino can accept players from everywhere in the world.
If you want an easy way to find the best and most trusted sites, take a look at our top casinos page. We only ever feature casinos that are licenced and verified as safe to use.
Understand RTP, volatility and house edge – Every slot game is based on luck, but there is a way you can get an idea of how frequently it pays out. The return to player (RTP) rate of a game essentially tells you how much you could theoretically win back from the game when playing over a long period of time. Basically, it’s the opposite of house edge and while your results can vary due to luck, generally, the higher the RTP rate, the better.
Make sure you look this information up before you play, most casinos will always publish the RTP rates of games on the site, and you can also check if these have been independently verified. With Bitcoin games, you can test the data out yourself as this should be publicly accessible. The other thing to check before you play is the volatility.
This is the measure of how often the game pays out and the size of the payouts. High volatility games payout less frequently but with larger rewards. Low volatility games pay out more often, but the payouts are smaller.
Check the rules and paytables before you play – Any slot should have an information page and paytable that shows you the different symbols and what they’re worth. You’ll also find the full rules here and details of any bonuses and special features to look out for. Knowing the paytable won’t just help you to know which symbols to look out but will also give you an idea of the payouts in the game.
You may also find details of the maximum win and whether there are any jackpots available. This information helps if you want to win big as you’ll know how to land wins and how to use the bonus features to your advantage.
Don’t bet too much of your bankroll per spin – Your bankroll is the amount of money you have to play with. Some people think that by playing with the maximum bet, you can increase the chances of a payout. Luckily, it doesn’t work this way, and you’re just as likely to win with the minimum as you are with the maximum.
If you’re playing a highly volatile game, you might want to set your stake a little lower than you usually play with as the chances of a win will be lower. Keep an eye on your bankroll as you play and set a limit on how much you can comfortably lose. Make sure you stop playing when you hit your limit as sometimes, luck just isn’t on your side.
You should also have a win limit as it’s always best to quit while you’re ahead. Stopping playing after you land a big win is much more satisfying than continuing and losing it all.
Make the most of free spins and other bonuses – Almost every online casino hands out big welcome offers to new players and Bitcoin casinos are no exception. A lot of casinos will also provide regular offers and promotions to their current players. If you want to maximise your winnings, you should take advantage of these whenever you find them. Be sure to check the box to receive regular promotions by email when you first sign up to your casino.
You should also check our top casino bonus page regularly as we keep it updated with the best online casinos bonuses we find. Check what kind of wagering requirements that a bonus has and if there are any restrictions about which games it can be used on and when it expires. You can use these bonuses to essentially play for free, landing big wins at the slots without risking your own personal funds.
Look out for casino slot tournaments – While slots are usually a solitary gaming experience, some casinos let you join I the fun with other players by hosting tournaments. In these competitions, players will earn points whenever they play certain games. If you earn enough points, you’ll be able to top the leaderboard, and at the end of the tournament, those at the top can win big prizes.
Some casinos offer huge cash prizes, holidays and even cars to tournament winners. Find out all the latest tournaments and details of what you can win by checking out our online casino tournament page.
Play for free before you risk your own cash – Playing for free is a great way to test a game out and decide whether it’s right for you. You might think a game looks like a lot of fun to play at first, but when you actually start spinning, maybe it has a feature that you don’t enjoy. Normally, you’d have to risk your own cash to find that out. However, many online casinos now offer players the chance to try out games for free.
Provided you’re signed into your account, you can play a free demo of most top games, testing all the different features out before you play with real cash. Of course, you won’t be able to cash out any of your winnings when you play for free, but it’s always good to get to know a game before you play with real money.
