A brief history of slot machines

First things first. We love this subject, and we like to look back to those good old days when the only slot machines available were those found at the pub of the local bookies Slot machines have been around in the UK for decades, and are more commonly known as fruit machines, puggy (in Scottish), or simply slots. They were also known as one-armed bandits due to the lever to the side of the machine, and of course, due to the risk of leaving the player in debt!

Jackpot Jester 50,000 slot


The first slot machine was developed in 1891 by the New York company Sittman and Pitt. This machine consisted of 5 drums and displayed playing cards instead of the usual slot machine symbols. Winnings were made if players managed to line up poker hands. Later in the nineteenth century, Charles Augustus Fey is said to have created the first proper slot machine. This machine was able to issue automatic payouts and consisted of only 3 reels. The playing cards were now replaced with 5 symbols: hearts, diamonds, spades, horseshoes and the liberty bell. The highest payout for this game was awarded for 3 bell symbols, and hence this machine was also called the Liberty Bell.

The Liberty Bell continued to be manufactured in America even following a ban on gambling in 1902. Prizes were paid out in chewing gum and sweets in the flavours of the corresponding fruit symbols instead, which must have been pretty fun anyway! Fruit machines became commonplace in the UK in the 1960s at local pubs and amusement arcades. This is when they started to look more like the online slot machines we play today. However, online casinos only started to gain an adequate presence in the 1990s, and as technology continued to advance, more feature-packed online slot machines started to be developed, so that nowadays we have slots with over 50 paylines and multiple features like bonus games, free spins, multipliers, wilds and additional gamble features! And, you can find hundreds of free online slots machines by the best developers like NetEnt, Microgaming, NextGen Gaming and many other emerging developers who are constantly coming up with innovative games!

Where to find free online slot machines

You can play online slot machines for free at almost any online casino licensed to operate for the UK market. Most of these casinos offer slots that can be played just for fun instantly, without the need for download or to even create an account. To play free online slot machines, simply head over to a casino’s slots category and browse through the games (a lot of casinos make a distinction between video slots and slots or slot machines, and you'll be able to locate online fruit machines under the latter). Click on ‘play for fun’ or an equivalent button and you’ll be able to play the game with fake coins.

Online slot machine bonus

If you decide that you want to play these games for real money, you would have to create an account with the casino by registering with your name and email address. Most online casinos also offer a welcome bonus in the form of bonus funds which you can use to play online slot machines.

Normally, you will have to play through the bonus amount a number of times, which can be anything from 15 to 50 times. This is called a wagering requirement and is indicated in the bonus terms by a number and the ‘x’ symbol. For instance, a 30x wagering requirement would require you to play through a £100 bonus for 30 times, staking £3,000 in total.

Some casinos also offer a free spins no deposit bonus which allows you to play a slot machine for real money without staking any of your own! In this case you normally get a set number of spins (normally between 20 and 50), with a specific coin value (normally on the low side, about 20p), and you’ll be able to win real money from these spins. And, if it's a wager-free no deposit bonus, you will get to withdraw these winnings instantly, without the need to play it through a number of times!

What to expect of modern online slot machines

Developers of online fruit machines strive to retain the classic element that’s reminiscent of the pub-style slot machines that we all love so much. A lot of online slot machines feature the traditional fruit, bell and bar symbols, but may come with an additional wild or bonus symbol, as well as features such as respins, free spins, bonus games, and of course, jackpots! In fact, payouts for online slot machines can be much higher than those that are paid out by physical machines, because some of these games are linked to what we call network progressive jackpots – these are jackpots that are fed by players across a number of online casinos who are spinning on the same game, and which keep increasing until this jackpot is won by one lucky player! One great jackpot slot with a nice take on the classic fruit machine would be Jackpot Jester 50,000 slot, with its maximum jackpot of 50,000x your stake!
