What Is RTP? Return to Player and House Edge Explained
Updated 2026-08-31
RTP (return to player) is the share of all money wagered on a game that the game pays back over a very large number of rounds. A 96% RTP means that across millions of rounds, $96 is returned for every $100 staked. The remaining 4% is the house edge.
RTP is a long-run average, not a session promise
RTP is calculated over the full distribution of a game's outcomes. A single session of 50 spins can return 0% or 500% and still be perfectly consistent with a 96% RTP.
The larger the number of rounds, the closer real results move to the theoretical figure. This is the law of large numbers, and it works in the operator's favour by design.
No strategy applied to a fixed-RTP game changes that number. Bet sizing changes how fast you get there, not where you arrive.
House edge is the mirror image
House edge = 100% − RTP. A 97% RTP game has a 3% edge; a 94% game has 6%.
In table games the edge comes from the payout table: European roulette pays 35:1 on a number with 37 pockets, which is a 2.7% edge.
In originals such as crash, dice or mines, the edge is applied to the multiplier shown, which is why the quoted multiplier is always slightly below the true odds.
Volatility is a separate dimension
Two games can share the same RTP and feel completely different. Low volatility pays small and often; high volatility pays rarely and large.
Volatility determines the size of your swings and therefore how big a bankroll you need to survive a bad run.
If you want long play time on a fixed budget, prioritise low volatility over a marginally higher RTP.
How to read RTP responsibly
Expected loss per hour ≈ bet size × rounds per hour × house edge. At $1 a round, 300 rounds an hour and a 4% edge, that is about $12 an hour on average.
Because the average is negative, the only reliable way to control cost is to control stake size and time played.
Treat published RTP as a spec sheet, not a forecast for your evening.
