Volatility
extreme
The average cost is total bets × (100% − RTP). Real sessions swing far above or below it, and more so the higher the volatility. 500 spins is roughly an hour of play.
How it works
Mental is built around special mechanics that transform symbols and add multipliers across the reels, so a single spin can change dramatically. It takes a few sessions to understand what each feature does.
Bonus features
Its free spins rounds come in several levels, with more powerful features the higher you go. The biggest wins almost always come from the bonus rounds, which can take a long time to trigger.
Our tips before you play
Extreme volatility means most sessions end with a loss and a few rare ones pay very big. Only play with a small budget you're ready to lose, and be very careful with bonus buys.
