Play the best online slots at Spin Casino

With the incredible selection of online slots available to play at Spin Casino, it’s easy to forgot how far we’ve come since ‘one-armed bandit’ style slot machines first began to appear in the saloon bars of the United States, around the start of the 20th century.

Where once there were three reels with standardised symbols and players could only repeatedly pull on that one lever – now there are thousands of online slots, each offering a unique blend of themes, rules and special features which keep players involved and engaged as they hunt out those all-important jackpots.

Here at Spin Casino, you’ll find a carefully curated selection of the world’s most popular slots, with designs, features and themes hand-picked to appeal to players of every taste and experience level. You’ll also find opportunities to win truly epic sums, thanks to progressive jackpots, which grow with each spin of the reels until some lucky player scoops the lot. From Rainbow Riches to Mega Moolah, if you’re looking to play online slots in the UK and beyond, Spin is the place to be.


How to play online casino slots

Though the dazzling range of themes and features mean that Spin Casino’s online slot games offer a world of choice, when you drill down to the fundamentals, the same, simple mechanics apply – straightforward and easy to pick up.

Any given slot machine will have a set number of ‘reels’ – separate vertical columns each comprising a number of individual symbols - which move in order to randomise their order. This is so a new and unique selection of symbols are presented across the horizontal rows of the gameboard with each ‘spin’ the player instigates. As with the circular drums fitted inside real-world mechanical slot machines, the individual reels commonly roll for a randomised period of time before settling in a new position, however, some online slots add a modern twist by having ‘cascading’ reels, with which the symbols drop into the playboard from above.

Simply select your ‘stake’ (the amount you pay for each spin) and spin the reels. Matching symbols is the order of the day, with cash prizes awarded for duplicating pre-determined numbers of identical symbols in connected ‘paylines’ at the end of the ‘spin’ phase. Paylines must usually be formed from left to right, starting at the left-most reel (though some games or special features bypass this requirement), and can usually be formed of either straight or diagonal lines traced from one reel to that adjacent to it on the right.

It commonly takes a payline formed of at least three symbols to win a prize, but details of the exact requirements for any slot you choose to play can be found in the ‘paytable’ – showing which symbols in which quantities earn which prizes. It may take a click to ‘expand’ the paytable into full view. To a large extent, the size of your prize depends on the size of your stake, as an online slot’s jackpots are usually expressed as multiples of the stake. A slot might offer a top prize of ‘1000x’, meaning your prize for landing the required combination of symbols will be 1000 times the stake you span for (e.g., £1000, if you were playing at £1 per spin).


Online slot special features

Though the core symbol-matching mechanics are the same, it’s a given online game’s special features which lends it character. As well as the prizes offered for matching groups of unique symbols in paylines, special features are usually triggered by their respective symbols appearing – either as part of a payline, or in some cases, anywhere on the game board.

Some special features unlock themed ‘mini-games’, totally unique to the slot in question, with set prizes up for grabs, while others are more common and will tend to be offered in some form on each slot you play.

Special online slot features might offer the opportunity to count one symbol as another for the purposes of forming a payline, or to scatter the symbols and offer a second shot at prizes after the initial spin. In this manner, special features add value to your play by making a winning combination more likely or extending the spin so that there’s an increased chance of landing a ‘natural’ win.


Free spins

One of those special features which you’ll find in one form or another on almost every online slot game in Spin Casino’s catalogue is free spins. As you may have gathered for yourself, these offer you the chance to spin the reels for free – without a stake being deducted from you balance.

Exactly how free spins work depends on the slot you’re playing. In some cases, there’ll be a ‘free spin’ symbol, and for each that you land on the game board, you’ll be entitled to one free spin, meaning one free shot at a prize. Otherwise, free spins might be awarded for landing a particular combination of symbols, for landing a certain quantity of ‘scatter’ symbols, or as the prize in a themed mini-game.


Online slot bonus

Another route to earning free spins is Spin Casino’s very own online slot bonus, which awards 20 free spins to every player who has staked at least £50 in the preceding 60 days every Sunday.

With such a wide range of online slots on offer, the online slot bonus is the perfect way to try before you buy – helping to find the slots that you enjoy playing (and potentially winning cash while you do it) without committing funds from your balance.


What are the best slots to play?

When it comes to those rich themes, you’d be hard-pressed to find a better example of the classic slot machine style than Rainbow Riches. Frequently topping the charts as the world’s most popular slot, Rainbow Riches offers players the chance to go in search of the legendary gold at the end of the rainbow in a colourful adventure featuring leprechauns and clover.

Elsewhere, history buffs will feel at home with the Cleopatra slot, with hieroglyphics and other icons of ancient Egypt filling the reels as players aim to take their share of the legendary Queen’s treasure. Meanwhile, fans of hit fantasy TV are likely to find a lot to like about the Game of Thrones™ slot, which forces players to choose which house of Westeros they wish to represent as they lay claim to the Iron Throne, and with it some potentially huge jackpots.

An if it’s huge jackpots you’re after, Mega Moolah certainly fits the bill. This international smash hit is one of the most popular progressive jackpot slots in the world, and has broken the record for world’s richest slot on multiple occasions, after bestowing prizes reaching into the tens of millions to a handful of lucky players.


How to win when playing online slots?

When deciding which slots you want to play, your own preference for themes, styles and features should lead the way.

But, when it comes to winning, you should consider a slot’s ‘volatility’ too. Expressed as a percentage, this figure represents the likelihood of any given spin resulting in a prize - the higher the number, the more volatile and liable to pay out the slot is. Look for the volatility figure in the information panel for your game.

When drawing up a strategy, you should also consider the availability of free spin bonuses, which give you a chance of a prize without any outlay, as well as any other special features which might keep you on the trail of a payout for longer or boost the amount you stand to win when you land one.
