How winnings work (members only)
What 94% RTP costs per $100 wagered, the 11,340x max win at a $1 stake

What 94% RTP means
Expected return = stake × 94%
Over $100 of total bets, the long-run average loss is $6.00
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a high volatility game.
Features explained (members only)
3 features explained: hold and win, respins, fixed jackpots
Hold and win
Landing enough special cash or coin symbols starts a respin feature: those symbols lock in place, the respin counter resets each time a new one lands, and their values are collected when the feature ends.
Respins
Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.
Fixed jackpots
Jackpot prizes set at fixed multiples of your stake, such as Mini, Minor, Major and Grand.
Strategy tips (members only)
- Size your stake to the volatility. High volatility concentrates the return in rare, large wins. Long losing runs are normal. Keep stakes small (around 1% of your session budget or less) so you can ride out the swings. A simple rule: bring at least 300 spins' worth of budget, so a $50 budget suggests a stake of about $0.17.
2 more tips and a session planner
- Bonus wagering: at 94% RTP, clearing $1,000 of wagering costs about $60.00 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.
