Online Slot Variations

There are different types of slots that you can encounter when you are making your way through the online casino world, and we are now going to take some time to explain the main ones for you.

Classic Slots (Three-Reel Slots)

The very first slot games came with just the solitary payline and three reels. The symbols were usually fruit such as lemons, cherries, and oranges while other common symbols included bells and lucky 7s. Such online slot games are still popular in the iGaming industry, but they do not come equipped with bonus features and additional paylines. Some Brits who like to play online slots for real money just enjoy having a sense of nostalgia.

Video Slots

As is clear from the name, video slots have an extra layer of multimedia. Alongside the buttons and reels that you would expect to find in a regular slot, video slots often come with thematic graphics, sounds, and fun animations. In his respect, you can say that they are a mix between a classic fruit machine and an arcade game. These games are usually equipped with bonus features and can have extra paylines and reels to increase excitement levels.

Multi-Payline Slots

A payline in a slot game is a line on which a payout will be awarded if you manage to land a winning combination along it - the more paylines that a slot has, the higher your chances of scoring a win will be. A multi-payline slot game is simply a game that has more than one payline present. Most slot titles that you will come across will fit into this category since the average slot game now features 20-25 paylines. The paylines can be horizontal, diagonal, vertical, or zigzagging across the reels.

Progressive Jackpot Slots

Progressive slot games are ones that have a jackpot which will keep increasing in size until someone is fortunate enough to land the winning combination that will unlock it. Once someone has won it, the jackpot size will reset to a predetermined amount and will start to grow until it is won again. These are some of the most popular online slots UK due to the fact that huge prizes can be won for relatively small wagers.

Megaways Slots

Many slot enthusiasts love megaway slot games because they have innovative reel mechanics that offer anywhere between 243 and 117,649 different ways to win every spin. Each spin that you make on a megaways slot game is unique and you never know how many paylines are going to be active on your very next spin. We have the software developer Big Time Gaming to thank for this exciting feature as they developed the concept back in 2015.
