Popular Slots Games

There are a huge selection of slot sites to choose from, with each offering wide range of games to play. Here is a quick overview of the different types:

Classic 3-reels

This is the simplest version of slots. The aim of the game is to line up three matching symbols along one pay-line. Playing this design will help understand the basic fundamentals of playing online slots.

5-reel Slots

Two additional reels take online slots games to another level, with players able to benefit from multiple pay-lines giving them even more opportunities to win.

Video Slots

This format takes the 5-reel slot and applies additional graphics to further enhance the gameplay experience. Video slots include animations, additional features, and different symbols. These are generally themed around comic book characters, famous movies or television shows.

Progressive Jackpots

Progressive jackpots are a prize pot that increases with every bet placed on slot sites in the UK. The jackpot keeps rising until someone wins and the amounts can often be life-changing sums of money. To win the jackpot you must match the specific winning symbols with a maximum bet spin.

Free Spins

Many online casinos offer sign-up promotions in the form of a deposit bonus, a no deposit bonus, free play credits or free spins. Players can use these types of promotions to build up their bankroll without depositing any of their own money. Free spins are a popular type of bonus, but make sure you choose the one that is right for you. Many slot site operators require you to “play through” a specific number of times before you win real money.

Game Rules

For people who have played slots in a real casino, the online versions will feel very familiar. The player simply chooses their game, decides on the number of pay-lines to activate, places their bet and presses the spin button. They are paid out any winnings according to a pre-determined payout table if they are successful.

A single online slot game requires players to match symbols in one row, while multi-line games offer winning opportunities in multiple angles, including diagonally and horizontally.

Many slot sites in the UK offer bonus features on their games which have the potential to significantly boost your winnings. Scatter symbols trigger a bonus game or higher payouts wherever they land on the reels, while wild symbols substitute other symbols in the game to create winning combinations.

Some online slot games also have nudge and hold features. These allow you to press the respective buttons to either move a reel up or down or hold a symbol or symbols to create winning combinations or trigger bonus features.
