Bankroll survival simulator

How long could a bankroll last on Crystal Treasure? We simulate thousands of sessions from this game's published RTP and volatility — the long-run math, not a prediction of your next spin.

Volatility tier: High

Running simulation…
How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (95.50%), with wins capped at its top multiplier (6,853×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
