Conversely, you'll find progressive jackpots with large potential payouts have the lowest Return to Player figures. In the world of online gambling, you will often see the term RTP - but what does it mean? This basically explains the estimated amount of money a real money casino game is expected to pay out to the player. Some bettors think of the RTP as the opposite to the house edge.

These figures are regularly tested and collaborated by impartial third-party organisations and must be as part of the UKGC licencing conditions. The majority of the best online casinos UK will advertise the fact that they offer a long-term RTP of 95-97%, meaning the game looks to return 95 to 97% of every pound you bet with over a period of gameplay time. This is an average taken over a long period of time though, it doesn't mean if you wager £20 or even £100 on a slot game, your return would always be in this range. Going for the higher RTP games might seem the right path to follow, but sometimes you can get more value by playing slot games with a lower RTP. Casino games with a lower RTP generally see a lower prize percentage being offered and some casinos will pay 93% or lower. We live in a world where mobile apps are part and parcel of your online gambling journey.

Why would you pick these over a slot game with a higher RTP? Believe it or not, the lower RTP games offer bigger prizes.

The main question is ‘should you play lower RTP games?’ It once again goes back to what you want to get from gambling on these games. If you just want to win and do not care if the amount is low, then the higher RTP games will be for you.
