What the info screen lists
No special features are listed for this game in the sources we checked. Check the in-game info screen for details.
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 97% RTP, clearing $1,000 of wagering costs about $30.00 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.
