What Are Slot Games and How Do They Work?

Slot games are a type of gambling machine that feature several reels containing different symbols. The reels will spin to land on randomly generated combinations, some of which could see you receive fantastic cash payouts. Each game has a determined number of paylines that players can land winning clusters of symbols across. Reels are a primary aspect of any slot, and every slot game online has its own reel structure and can feature anywhere between 3 or more reels for you to play with. The more modern online slot titles tend to feature more reels, huge numbers of paylines and bundles of bonus rounds. You could find features such as free spins and huge multipliers. For an increased chance of winning, look to land bonus symbols across the reels, such as Scatters, Wilds and more!

What Are The Most Popular Slot Games at 21.co.uk

You can discover some of the best online slot games at 21.co.uk below.

MEGAWAYS: MEGAWAYS slots are one of the most innovative types of modern slot machines we’ve introduced to our online collection, presenting players with up to a colossal 117,649 possible ways to land a win each time you spin the reels.

Other notable mentions include the legendary Rainbow Riches MEGAWAYS, a great variation of the original classic.

Arcadic Fruit Machines: Following on from the popularity they formed in public houses and seaside arcades, fruit-themed slot machines have become solid staples of both land-based and online casinos which makes them some of the most recognisable games regardless of whether you’re a slot newbie or veteran player. Adorned with arguably the most distinguishable symbols in the business, such as cherries, bells, 7s and bars, Arcade Fruit Machines stand as some of the most iconic and popular slots of all time - some of our favourites include the likes of 7s On Fire and Mystery Reels Megaways.

Mobile Slots: A number of online slots in the modern day are created for handheld devices such as mobiles and tablets. You can find out all the crucial information surrounding these slots by checking out our mobile slots. Why have providers started prioritising mobile games, we hear you ask?

Cluster Win Mechanics: Cluster slots have become one of the latest crazes to take over the online slots world with titles such as the intergalactic Reactoonz and fruity Jammin’ Jars. Similar to regular online slots, the idea is to match as many symbols as possible. Often in cluster slots, there are a lot of symbols on the reels and gaining as many as you can together in a “cluster” often leads to bigger wins. They also take an aspect of cascading slots because as symbols are matched and disappear, more symbols fall in, giving you another chance to get even more cluster wins.

Cascading Reels: Cascading Reels slots (also known as Tumbling Reels) offer up extremely innovative, modern slot features that boosts the payout potential of online slot games significantly. Land multiple wins from a single spin, as each time a winning cluster is formed, the Cascading Reels feature works to remove all of the symbols involved in the win and allows fresh symbols to fall into their place. This will continue to occur until no more winning combinations can be made. We have numerous slots that include the Cascading Reels feature, with one of the most popular being Bonanza MEGAWAYS.
