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 88.12% RTP, clearing $1,000 of wagering costs about $118.80 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.
