Choose a slot, enter your bankroll, stake per spin, and number of spins. We run Monte Carlo simulations to estimate bust probability and expected outcomes.
Simulate Your Slot Session
This tool models thousands of sessions using the slot's RTP and maximum win to approximate variance. Results are estimates - always play responsibly.
This slot session calculator is designed to help you understand how long your bankroll can realistically last and what kind of risk you are taking with a given stake and number of spins.
Bankroll management for slot sessions
A solid slot bankroll strategy starts by deciding how much you can afford to lose and then choosing a stake per spin that spreads that amount over hundreds of spins. Smaller stakes usually mean more playing time and a lower chance of going bust early.
Understanding bust probability and variance
Bust probability tells you how likely it is that your bankroll will hit zero before you finish all planned spins.
High-volatility slots tend to have higher bust risk but also offer a greater chance of very large wins.
Lowering your stake per spin is one of the simplest ways to reduce bust risk and extend your session.
Why use a slot session calculator?
It helps you set realistic expectations about how your bankroll might behave over a full session.
You can compare different combinations of bankroll, stake and spins before you start playing.
It encourages healthier gambling habits by highlighting risk instead of only potential wins.
