How it works
Setting a bankroll and knowing how long it can last is the foundation of budget management. The average estimate is linear: each spin costs you, on average, the bet times the house edge (1 − RTP). Dividing the budget by this cost gives the number of theoretically sustainable spins.
It is a guide, not a guarantee: volatility swings the balance around the average. High-variance titles can burn the budget in a few dozen spins or grant very long sessions. Use the estimate to set a conscious limit on time and money — and stick to it.

FAQ
How is bankroll duration estimated?
By dividing the budget by the average loss per spin (bet × house edge). At 96% RTP and €1 a spin you lose ~€0.04 per round: €200 lasts about 5,000 spins.
Does volatility change the result?
Yes, a lot in the short run. The simulator shows the theoretical average; high-volatility games can bust much sooner or last longer.
