Balance over Time (20 Paths)
This simulator uses a Gaussian approximation of slot variance for illustrative purposes. Real slot outcomes follow different distributions. Results are not a guarantee of any actual outcome.
See how variance really hits your bankroll
Run Monte-Carlo simulations to understand the swings behind any RTP and volatility.
Monte-Carlo simulation
Run hundreds of thousands of spins across many simulated bankroll paths.
Multi-path balance chart

Bust rate
The share of runs that lose the entire balance.
Median, best and worst
Compare the median outcome with the luckiest and unluckiest runs.
Average max drawdown
How deep your balance typically dips before any recovery.
Profit paths
What share of simulated runs end in profit.
