3. History of slot machines

Slot machines have a long history and the first machines appeared in the late 1800’s in San Fransisco. Early slot machines had only card numbers instead of the fruit symbols that are common these days.

Other name for the machines is one-armed bandit, because they were originally operated by one lever on the side of the machine. Bandit because the machines very often took all the players money.

The name slot machine derives from the thin slots where you insert coins. Fruit machine – name comes from the traditional fruit images on the spinning reels. You can still play these classic fruit slots in online and Bitcoin casinos.

Slot machines are the most popular gambling type in brick-and-mortar casinos and consitute about 70 % of average US casino’s income.

The precursor to slot machines gets developed

Sittman and Pitt from Brooklyn, New York, US, developed a gambling machine in 1891 which was a precursor to the modern slot machine.

It contained five drums holding a total of 50 card faces and was based on poker.To make the odds better for the house, two cards were typically removed from the deck: the ten of spades and the jack of hearts, which doubles the odds against winning a royal flush.

This machine went extremely popular and soon many bars in the city had one or more of the machines. Players would insert a coin and pull a lever, which would spin the drums and the cards they held, the player hoping for a good poker hand.

There was no direct payout mechanism, so a pair of kings might get the player a free beer, whereas a royal flush could pay out cigars or drinks, the prizes wholly dependent on what was on offer at the local establishment.

The first real fruit slot machine

Due to the vast number of possible wins with the original poker card-based game, it proved practically impossible to come up with a way to make a machine capable of making an automatic payout for all possible winning combinations.

Between 1887 and 1895, Charles Fey of San Francisco, California, US, devised a much simpler automatic mechanism with three spinning reels containing a total of five symbols – horseshoes, diamonds, spades, hearts, and a Liberty Bell.

The bell gave the machine its name. By replacing ten cards with five symbols and using three reels instead of five drums, the complexity of reading a win was considerably reduced, allowing Fey to devise an effective automatic payout mechanism.

Three bells in a row produced the biggest payoff, ten nickels (50¢). Liberty Bell was a huge success and spawned a thriving mechanical gaming device industry.

Online gaming has evolved slot machines a lot since then. Online Bitcoin casinos have very wide range of different Bitcoin slots to choose from.

4. FAQ

What Slot Game Types are there?

There are actually a huge number of different Bitcoin Slots on the market at the moment. There are also a lot of different game types out there. Some of the most popular Bitcoin Slot game types are as follows:

Jackpot Slots

These are games that feature a jackpot. This is a prize that doesn’t have a limit on it. Most Bitcoin Slots have a limit on how much can be won, 500 times the stake for example. But a jackpot slot will continue rising until the prize is won. As such, these can offer incredible payouts that can sometimes make the lucky winner incredibly rich.

Cascading Reels

Cascading reels work slightly differently to normal Bitcoin Slots. In these games the symbols will fall into the reels instead of spinning. On top of this, whenever a win is created the symbols will be removed from the reels and new ones will fall in. These can then create another win without the player having to pay for another turn. Some will also increase multipliers as more wins are created in succession, allowing players to grab some incredible wins.

Megaways

The Megaways mechanic is a game feature that increases the number of rows and reels that are in play. On top of this it will also increase the paylines accordingly. With some megaways games you can get over 100,000 paylines on offer. This makes them very exciting and they can pay out some great prizes.

Are there Live Dealer Bitcoin Slots?

This is a tough question to answer. There are live dealer slots out there on the market. However, they’re not that popular at the moment. Because of the way video slot games are played, live dealer Bitcoin Slots aren’t a big part of the market. 

However, if you find a Bitcoin Casino that does offer the small selection of live dealer video slots, then there is a chance that you will be able to play it using Bitcoin. 

Can you get Provably Fair Bitcoin Slots?

A year ago the answer to this might have been quite different. However, there have been a lot of developments in the world of provably fair games recently. There are provably fair Bitcoin Slots out there and they are improving at quite a fast rate too. 

The first versions of provably fair Bitcoin slots were just very simple three reels slots. Quite similar to some of the older video slots on the market, or even old fashioned fruit machines. This has changed as some of the newer provably fair Bitcoin Slots include far more features and are much closer in quality to the standard Bitcoin Slots that are on the market.

It means two main things Firstly, the provably fair versions of Bitcoin Slots are the best titles to play if you want fairness and the best chance of winning. Secondly, it won’t be long before the quality of provably fair Bitcoin Slots is on a par, or even surpasses, the quality of regular Bitcoin Slots.

What is also great about provably fair Bitcoin Slots is that the RTP tends to be higher than on equivalent Bitcoin Slots. This helps to increase the chance of winning and creates better opportunities for players to walk away with a profit.

Should I Play Bitcoin Slots?

This is all down to your own desires. Bitcoin Slots are definitely some of the most exciting and enjoyable casino games on the market. The extensive features, fast paced gameplay and large payouts on offer help to make them appealing to all kinds of players. This doesn’t mean that everyone will enjoy them though.

Some players might prefer a slower paced game, something that offers the opportunity to breathe a little before taking the next step. On top of this, a game such as Blackjack offers players the chance to have more of an impact on the outcome of the game. This could be something that players prefer, as Bitcoin Slots are pretty much all down to how the algorithm works. 

The fact remains though, Bitcoin Slots are the game to go for if you want big wins and lots of excitement. If this is the kind of gameplay that you’re looking for then the choice is a simple one. If you want fast spins and big payouts then Bitcoin Slots are definitely for you. If you want a slower paced game them you will be better off looking elsewhere.

5. Final thoughts

Positives of Playing Bitcoin Slots

Bitcoin Slots are without a doubt the most popular casino game there is. They make up the vast majority of game choice for players and as such there is quite a lot to know about them. There are a lot of positives to Bitcoin Slots, which is why they have lasted so long and been able to be so popular. Here’s the great things that you can expect from Bitcoin Slots.

Extremely Fast Paced

When you’re playing a Bitcoin Slot one of the first things that you will notice is that they play quickly. Every single spin doesn’t take long to carry out and there is another spin coming right after it too. This instantly appeals to players because it’s exciting. While winning money is the first aspect that players aim for, enjoyment is high up there too. Video slots are so fast paced and enjoyable that lots of players just play the demo versions for fun.

Lots of Features Included

What a lot of players don’t like about other casino games is that there isn’t a lot of variation in the gameplay for each one. This isn’t the case when it comes to Bitcoin Slots. Players are able to enjoy a range of features in each game that helps to keep it interesting. The different symbols that land on the reels can behave in different ways and on top of this there can be bonus games included. This helps to make each game unique and to keep innovation at a high level.

Great Wins are Available

Table games don’t tend to have huge payouts on offer to players. Even Roulette only offers a 35/1 payout as a maximum. This isn’t the case with Bitcoin Slots. Here players are able to win incredible amounts. Some slots can even have payouts as high as 10,000/1 in place. On top of this there are jackpot slots that offer players the opportunity to win genuinely life changing amounts of money. 

When it comes to size of payout, Bitcoin Slots are right there at the top of the game.

Negatives of Playing Bitcoin Slots

Of course, it’s not all perfect when playing Bitcoin Slots. There are some negatives to them. We have gone over the most important negative aspects to make sure that you are completely aware of how the game works when you start playing.

No Skill Involved with Playing

This is a bit of a nuanced one. There is no skill involved in playing the actual game itself. So it means that you can’t impact how the reels spin when you play. This is in contrast to a game like Blackjack where your ability as a player will make it more likely that you win. However, you can slightly increase your chances of winning if you manage your bankroll properly. This isn’t an exact science though, which does make it difficult for some players to fully engage with Bitcoin Slots.

Some Titles can have Very Low RTPs

This is an aspect that a lot of players don’t fully understand. The RTP is the Return To Player value of a game. It’s expressed as a percentage and the lower the value the smaller the chance you have of winning. The RTP rate for some Bitcoin Slot games is extremely low. This can make them extremely poor choices to play. This is why it’s important to check before you begin playing so that you’re fully aware of what your chances of walking away with a profit are.
