What is RTP & Why Should You Care?
RTP Explained
-
RTP (Return to Player) is the percentage of all wagered money a slot pays back to players over time.
-
Example: A slot with 96% RTP returns £96 for every £100 wagered (on average).
-
Higher RTP = Better long-term payouts.
Why RTP Matters for UK Players
✔ More value for your money – Slots with 97%+ RTP give you a better chance to win.
✔ Lower house edge – A 96% RTP slot has a 4% house edge, while a 98% RTP slot only has 2%.
✔ Better bonus playthrough – High RTP slots help you meet wagering requirements faster.
💡 Pro Tip: Always check a slot’s RTP before playing—some games have multiple RTP versions (avoid the lower ones!).
