So, keeping things simple, this is the basic categorisation when it comes to slots — 3 vs 5 reels. The classic 3-reel format is still quite popular to this day, especially for fans of retro looks, but 5-reel slots have been leading the way for some time now.

Most of the new video slot games you can find at the best slot sites UK have five reels — or sometimes even more! Even without considering the number of reels, there are literally thousands of different slot variations and themes.

There are, of course, other characteristics that could put slots into different categories. For instance, a slot could have a progressive or non-progressive jackpot.

Progressive jackpot slots can offer some mind-blowing prizes. Depending on the casino policies, the money could be gathered from just this one game or from multiple slots, and even online slots sites, at the same time.

Progressive jackpots often get huge, and you will see them featured on the home page of many online casinos. The record is yet to be broken, though it has come close a few times.

Slot machines have 3 or 5 reels with symbols all over them. When identical symbols appear in a certain pattern, called a payline, you win a sum of money depending on the number of identical symbols and their value according to the paytable.

At land-based casinos, you spin the wheels by pulling a lever or hitting a button. Once you initiate a round, all you can do is hope that three or more of the same symbols will land on a payline.

Usually, the symbols need not only to appear on a payline but also to start from the leftmost reel. As far as symbols go, these can be pretty much anything you can imagine.

They fit the themes of the online slots beautifully and add to your gaming experience immensely. However, certain special symbols are featured in almost all slot machines in one form or another.

These three special symbols are the most common ones but, in fact, there are a lot more. Make sure you check out our slot reviews, where we give you all the important info on each game separately.

We believe that would be a much more helpful way for you to discover the particulars of special symbols. There are many advantages of playing slots online rather than at a brick-and-mortar casino.

There is a great variety of games and welcome bonuses, no doubt, but there are also multiple ways to enhance your experience that are not available offline.

Those personalisation options not only customise your game but can actually help you save time and get to those big winnings faster.

Take the slots of Thunderkick as an example. You can do that in two ways. You can choose a preset number of spins to be performed, and some of the best online slots sites even provide the option to auto spin until reaching a bonus round, which is really great.

Both time-saving options come handy when you need to play through a welcome bonus or another promotion. Certainly, you can also adjust the technical aspects of the game — graphic quality, sound level, etc.

Those options are especially useful as slot games can be quite noisy. The variety of those options depends on the slot site and the game itself.

Newer games generally look way better and have more settings to play with. Of course, you can enjoy the best gambling games even if you are not a fan of slots.

The online gambling industry keeps on growing and evolving and there are plenty of companies that create cutting-edge software for it.

A low variance casino game produces smaller winnings at regular intervals, while a high variance game pays out a higher sum less frequently. The classic casino game blackjack is a low variance game.

Progressive jackpot games have high variance and can be a long time between wins. Slots with progressive jackpots are a type of game that attracts many players who are drawn to the chance to take home a more substantial sum of money.

It can be a long time between the jackpots, but sometimes a lucky winner has the turn on his side and picks home a huge jackpot.
