Top 10 Most Popular Slot Games in The Uk

There are thousands of slot games at UK online slot casinos. However, only a few stand out. These few games have been selected based on their RTP and other juicy perks they offer. Also, these games were created by the best hands in the game, which counts for something. Find below a compilation of the top 10 popular slot games in the UK:

How Online Slots Work

A typical slot machine is characterized by a minimum of 3 reels (the number of reels could be more). Players are only expected to place a stake on the pay lines and take a spin. You win when you land three or more matching symbols, depending on the particular slot game. The online slot machines have this similar attribute, only that the process is digitized as you get to stake and play at an online casino.

Slot is mostly a game of luck, and its outcome can be rigged, especially if you’re playing at an online casino. To avoid falling into the wrong hands, it’s advisable to play at an online casino that has RNG in its system. The Random Number Generator (RNG) is special software that primarily helps to determine the outcome of slot games, especially when played online. So, to be on the safe side, ensure that the casino you’re choosing is probably fair.

Advantages Of Online Vs Brick and Mortar Slots

The truth is that we live in an age of technology, and by far, opting for an online casino would be the most rational and logical decision any serious slot bettor can make. Land-based casinos used to be in vogue when there was no internet, and of course, punters didn’t mind going from place to place in search of a good casino. This is not the case now as everything has changed. However, while it’s true that online casinos have facilitated increased accessibility to casino games, the truth remains that brick-and-mortar casinos still give a perfect sense of belonging as you get to interact with other players while playing. Here are some of the advantages online casinos have over land-based ones.

Increased access

You can log in at any time and from the comfort of your room to play any favourite game. You don't have to get to go through the stress of leaving your comfort zone before you can play.

Juicy bonuses

Unlike land-based casinos, online casinos offer attractive bonuses to their players. While the primary reason why online casinos give bonuses is to woo players to their site, the fact is that smart players can reap good benefits by putting the bonuses to good use.

Safety

An online casino, especially one with RNG, would produce fairer outcomes, unlike a physical slot machine which may be rigged. Also, payments made at an online slot can be traced easily should any issue occur. This is not the case with land-based slot machines.

Slot varieties

Playing at the right online casino gives you access to a large range of slot games. There are several thousands of slot games available for play. The competition is real among top-notch slot software creators, so more varieties of slot games are reeled out daily to satiate the players' desire.

Live slot

You can also opt to play live slot games without moving an inch away from the comfort of your home. The game can get streamed to you in HD quality, and you can participate for as long as you desire.

Slot Bonuses

There’s hardly any new online slots in the UK without bonuses. These bonuses are quite a thing as they allow you to take more from the slot game. There are several types of slot bonuses which include but are not limited to free spins, multipliers, and jackpots.

There’s something peculiar to note about slot bonuses, and that’s the fact that they can only be activated with symbols featured in the slot game. Suffice to say, a typical slot game comes with several symbols, with each performing specific functions. Some of the most common symbols in slot games include the following:

Wild or random symbols

The wild symbol is one popular symbol that comes with every slot. It can replace all other regular symbols in the reel; thus, creating more possible winning combinations. There are several types of wilds depending on the creativity in the games. There are walking or moving wilds, stacked wilds and all.

Stacked wild or a group of random symbols

Just like its name implies, the stack wild functions like the wild, only that it comes in a group of 2 to 5 symbols. It also can replace normal symbols and can create room for more matching symbols on the payline. The stacked wild moves in the vertical direction and occupies any free space it finds on the reel.

Sticky wild

Also functions like the wild but with an additional feature is the sticky wild. Typically, a wild can replace a regular symbol and vanishes after a winning match is produced. A sticky wild does not vanish; it sticks around and expires after several spins. It’s mostly activated during the free bonus round.

Expanding wild

This wild can stretch beyond its reel to other available positions. It can expand towards any direction, thus, replacing every regular symbol on its path. An expanding wild can come in handy for winning massively. The only downside about this wild is that it can’t be triggered easily, and most times, it can only be activated on a particular reel.

Scatter or additional game

Scatter symbols are useful mostly for activating the free spin bonus round. It also can be used to retrigger a bonus round. Landing several matching scatter symbols can give good payouts too.

Free slot games

Most slots online feature demo versions that beginners can use to understand the intricacies of the game. However, free slot games cannot be played with real cash. That’s the idea; it can only be played with free credits earned in the free play. To play free slots online, opt for a good casino.
