Session cost calculator
See what a session costs on average, game by game, from the house edge, your stake and how fast you play. Compare blackjack, roulette, baccarat, video poker and slots.
Filled in with a typical pace for the game. Live tables are slower than online slots.
Same stake, same hour: game by game
At your stake, for one hour at each game’s typical pace:
| Game | House edge | Bets an hour | Average cost |
|---|
How it works
Average cost = total staked × house edge. A £1 bet at 2.7% costs 2.7p on average, so 50 spins an hour costs about £1.35. Fast games add up: a 96% slot at 500 spins an hour costs about £20 at £1 a spin, even though the edge is only 4%.
Questions
Why is a slot so expensive per hour?
Speed. Each spin has a small edge, but you can play hundreds of spins an hour, so the total staked, and the average cost, grows quickly.
What does house edge mean?
It’s the average share of each bet the casino keeps over the long run. It’s 100% minus the RTP.
