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. 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 95.25% RTP, clearing $1,000 of wagering costs about $47.50 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.
