Strategy tips (members only)
- Size your stake to the volatility. Medium volatility balances hit rate and win size. Expect dry spells between features, but not extreme swings. A simple rule: bring at least 200 spins' worth of budget, so a $50 budget suggests a stake of about $0.25.
2 more tips and a session planner
- Bonus wagering: at 95.78% RTP, clearing $1,000 of wagering costs about $42.20 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.
