Session calculator

Slots are priced, not random in your favour. Enter a bankroll, a stake and the game's advertised return-to-player and this works out what the arithmetic expects an hour to cost.

Staked per hour300.00
Expected cost per hour−12.00

At 96.0% RTP you stake 300.00 an hour and the game is expected to keep 12.00 of it. A bankroll of 100.00 lasts about 8.3 hours on average.

What this does and does not tell you

  • RTP is a long-run average, measured over millions of spins. Your session is far too short to land on it. Half the sessions will do worse than the figure above, some much worse, and a few will finish ahead.
  • The cost is driven by turnover, not by luck. Doubling your stake or playing twice as fast doubles the expected cost, whatever the game.
  • Nothing changes the RTP. Stake patterns, "hot" machines and betting systems do not alter the number the game is built around.
