Slot Themes

Almost all online slot games showcase different themes to one another. Unless, the slot is a re-invention of a classic slot game, chances are no two games will look the same. However, slot game developers often take inspiration from the same sources. Slots based on Ancient Greece and Rome are common, as are fantasy themed slots and even game show themed online slots.

From a theme point of view, you should ensure that you pick an online slot which you like the look of, one that has a pleasant soundtrack and smooth animations. All of our slot reviews feature screenshots of the respective slot game. One of our favourite slots from an aesthetics perspective is Genie Jackpots, a slot based on a magical Genie and his secret riches.

Slot Variance

Slot games come with three different slot variances. You will find low, medium and high variance slots.

Variance refers to how often a game pays out. For example, a high variance slot will not pay out as frequently as lower variances, however, when it does, it will pay out large amounts. Whereas the amount of money low variance slots will pay will be small but frequent.

The best high variance slots include games such as Book of Dead, Immortal Romance and Break Da Bank Again. Some of the most well played low variance slot games include Starburst, Thunderstruck II and Blood Suckers.

If you are looking to win big, then we can recommend that you play high variance slot games. On the other hand, if you are more interested in taking advantage of lots of small wins, then low variance slots are for you. If you are looking for something in between, then check out medium variance slot games.

Slot Bonuses

All modern day slot sites and casino slot games come with bonuses. You will be able to use slots bonuses such as free spins on most online slot games.

A new slot bonus which is incorporated into all Jumpman Gaming casinos is the Mega Reels slot bonus. Mega Reels allows you to spin a mega reel and if you are lucky, you can win some great prizes including 100 free spins!

Check out our Mega Reel sites guide to discover where you can try out this original and innovative slots bonus.

Slot RTP

You need to take into account the Return to Player percentage (RTP) when choosing a slot game to play. RTP refers to the average amount of money that is paid to players in prizes. 

To give you an example, Rainbow Riches Drops of Gold has an RTP of 97.75%. This typically means that for every £100 you wager on the game, £97.75 will be returned back to you. This does not mean that you will always miss out on 2.15% of your stake, it is just an average. Slot games are based on luck. One player might lose 100% of their stake whereas you might win 200% back – this is the thrill of online slots after all!

Our high RTP slots page tells you the 15 highest RTP slot games.

Slot Developers

Please remember that it is not the online casinos that develop and design online slots. Slots are created and developed by game studios, of which there are many that are producing online slots.

The biggest slot developers are NetEnt, Microgaming and Scientific Games; at Labslots, you will find slot reviews of games created by these developers. We have also reviewed slots by the following slots developers: Yggdrasil gaming, Big Time Gaming, Thunderkick and many more. You can also find our list of the best Evolution Live Casino games.

Licensed and Fair-to-Play Slots

The final thing to know is that whilst choosing an online slot to play, please don’t forget to ensure the casino and their slot suppliers are fully licensed and regulated by a gaming jurisdiction such as the UK Gambling Commission. The UK gambling market is one of the strictest in the world and will not allow shady casinos to enter it. Therefore, if you visit a casino with the UKGC stamp of approval, it is safe to play at.
