Online Slots UK - Top Variations

Online slots games aren't exactly an overnight sensation. What started out as a simple five-barrel game based on poker slowly morphed into fruit machines, and eventually the video slots games older UK players might have known in the 1970s. After the internet made its way into all of our homes, online slots were crowned king. Now everyone across the United Kingdom can enjoy every conceivable kind of slot machine from the comfort of home. You can even experience the excitement on the go, with mobile online casino slots for real money.

When playing, whether that's free online slots or for real money, you can opt for traditional 3-reel or more elaborate 5-reel games. You'll find both options available at both desktop and mobile internet casinos in the United Kingdom. Try both styles of play in the UK and see which one gets your heart palpitating the most. Aside from these two variations, there are also other types such as video and themed slots. Read more about them in our slots guide.

Three Reel Slots

Celebrated for their simplicity, three reel slots are a UK casino classic. As the name suggest, these online slots feature just three spinning wheels. Despite offering fewer ways to win than their more complicated counterparts, the overall payouts are just as good if not better than the 5-reel tournaments. At UK online casinos, slots come in a variety of flavours. You'll find everything from traditional fruit machines to games with sports and entertainment themes. Some casino online slots offer hold and nudge features, which let you isolate one of your reels or reward you for near misses.

Five Reel Slots

If you've visited a live casino in the United Kingdom recently, you've probably noticed that many of today's slots online in the UK rival traditional video games in terms of graphics and animations. You'll find the same state of the art slots at online casinos. Play slots that feature five reels often have over a hundred pay lines. You'll not only find yourself winning more often in the UK, but five reel games often feature great bonus rounds. Experience the fun of playing a game within a game at casinos online. Slots can payout handsomely no matter how many reels are involved.

Huge Real Money Payouts

One of the ways casinos attract new players is through welcome incentives & bonuses, and the online slots casinos we recommend are no exception. From doubling your first real money deposit, to giving you pounds to play slots for free, you can be confident that the sign-up bonus claims our recommended slots casinos make are 100% authentic and offer the best terms for UK players.

If you've ever glanced at the home pages of casinos online, slots have probably commanded and gained your attention. At most online casinos in the UK, slots are simply the biggest draw. That's largely because slots are as simple as games get. Yet that's only half the story. Did you know you can win a huge jackpot even on a small bet? When you visit casinos online, slots with progressive jackpots can pay out hundreds of thousands and even millions of pounds to a lucky winner. What's even better is that the princely sum actually grows by the second until a fortunate gambler strikes gold. When you play progressive casino online slots, that person could be the suddenly wealthy version of you.

Cutting Edge Casino Technology

While the worth of any great online casino is measured by its player traffic and affiliates, one of the most essential factors is a wide range of excellent slots online games. The key to creating high-quality slots lies in producing superior software. Therefore, an entire industry is dedicated to UK gaming sites software, which progresses through processes such as conceptualizing, designing, manufacturing and supplying. There are various software platforms, including highly praised companies such as Cryptologic, IGT, Microgaming, NetEnt, Novomatic and Playtech. If you’re interested in finding a platform that best fits players from the United Kingdom, ensure it meets certain crucial criteria. Keep an eye out for fairness credentials intended to guarantee the legitimacy of their operations. Also consider quality and speed of graphics, stability, file sizes, and minimum & maximum payout.

The Popular Choice In Top Rated Online Slot Games

Unlike offline slots, online slot games can encourage players through plenty of enticing offers: like a giant online slots bonus, whopping jackpots and multiple free spins also. The only hitch you’ll face is going through the dilemma of choosing amongst the hundreds of games hosted on hundreds of online casinos. You can travel to the vast Egyptian desert and attempt to discover riches guarded fiercely by a mysterious but graceful panther through the Treasures of the Pyramids slot. Perhaps, you would be more interested in the treasures left behind by the Aztecs and join Gonzo the explorer on his conquest for the City of Gold in Gonzo’s Quest? Whether you’re a fan of tropical treats, rainbows, star-studded galaxies or action-packed adventures, slots at online casino sites have something you’re bound to love. Try classic player favourites such as Rainbow Riches, Starburst, Buffalo, Siberian Storm and Triple Diamond.

Selecting a slots online casino to play in really boils down to what you want to get out of the game itself. If you're in it simply for the entertainment value with no intention to wager real cash, then there are plenty of great free casino slots available to UK players. If you're hoping to make some money while you play then it's important to verify the security of the site you're playing at so you don't lose out down the line. Some online slots sites specialise in popular culture themes such as TV shows, musical icons, and cinema, while others prefer original animation that have been specially devised for the online slot platform.

Hitting A Giant, Juicy Jackpot

The beauty of spinning the wheel at online slot machines is the possibility of winning a tremendous amount of unbelievable riches. Anyone can get lucky and hit a jackpot but the question is, how do jackpots work and are there different types of jackpots? For starters, there are two basic types of jackpots - fixed and progressive jackpots.

On the majority of online casino slot games UK players can enjoy, the jackpot is an amount fixed by the software provider. Particular slots or online casino sites might claim to reward players with a 5,000 coin jackpot on its pay table, however, it pays this amount on one coin per line, on a wager. Meaning, if you were to play with 5 coins and activate each pay line, you could win 25,000 coins for the 5 coins per line. An excellent choice is the Avalon II slot by Microgaming that promises players a massive £120M+ jackpot simply with a £7.50 spin.

Progressive Jackpots consist of a pool where money accumulates each time someone plays at a particular online slot machine. The money pool can be fixed to the machines or spread across a network. From every bet placed on a slot machine, a percentage is claimed and added to the jackpot pool. This goes on and the pool continues to increase until an extremely lucky player triggers the jackpot. Megabucks, a slot developed by IGT, is the most famous of progressive jackpots. This slot is seeded at $10M (an estimated £7M) and has been known to reach an extreme $39M (£27M) before being triggered.
