Read more →What these guides cover
Every casino game has a built-in cost, expressed as RTP (return to player) or house edge. A game with 96% RTP keeps about £4 of every £100 staked over the long run. These guides explain how slots, roulette and blackjack work, how their odds compare, and why two games with the same RTP can feel very different to play because of volatility.
Knowing the numbers will not change the odds, but it helps you choose games that suit your budget and avoid the ones that cost the most. You can try many popular games without spending anything on our slot pages, which list RTP, volatility and maximum win for each game and include free demos where the studio provides one.
