High RTP = better theoretical returns over the long term
RTP ("Return to Player") indicates the percentage of stakes a game theoretically returns to players over time. A higher RTP can improve long-term chances – but each spin remains random.
📊 What does RTP mean?
RTP is the average return percentage calculated over millions of game rounds. A game with 97% RTP theoretically pays back £97 for every £100 wagered – over a very long period.
📝 Why is RTP relevant?
Games with higher RTP can statistically offer better returns over time. At bestcasinosbritain, we use RTP as one of several factors in our assessments, so you can make an informed choice.
🚫 No guarantee of winnings
RTP is a theoretical average – not a prediction for your next round. Results are determined by RNG and are always random. Treat gambling as entertainment, not a way to make money.
🔍 How to find RTP
Licensed casinos in the UK must display RTP for each game. bestcasinosbritain highlights this data in our reviews when available, so you can compare quickly.
