How winnings work (members only)

What 96% RTP costs per $100 wagered

What 96% RTP means

Expected return = stake × 96%
Over $100 of total bets, the long-run average loss is $4.00

RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a medium–high volatility game.

Features explained (members only)

1 feature explained: megaways

Megaways

A licensed mechanic where the number of symbols on each reel changes every spin, so the number of ways to win can run into the hundreds of thousands.

Strategy tips (members only)

Size your stake to the volatility. Medium-to-high volatility means longer gaps between meaningful wins, with most of the return concentrated in features. Use smaller stakes relative to your budget. A simple rule: bring at least 250 spins' worth of budget, so a $50 budget suggests a stake of about $0.20.

2 more tips and a session planner

Bonus wagering: at 96% RTP, clearing $1,000 of wagering costs about $40.00 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
