RTP (Return to Player): What It Really Means
RTP — 'Return to Player' — is the share of all money wagered that a game pays back over the long run. It's just the house edge flipped around, and it won't tell you whether you'll win tonight.

RTP is the house edge, flipped
If a game has a 5% house edge, its RTP is 95%: over millions of rounds, the game returns about $95 of every $100 wagered and keeps $5. The two always add up to 100%:
RTP + house edge = 100%
So a "high RTP" game is simply a "low house edge" game. Here's how a few common games compare:
The bars use a magnified 90%–100% scale — a 99.5% vs 94.7% gap is almost invisible on a full 0–100% axis, so the chart zooms in to make the differences readable. Blackjack's RTP assumes basic strategy; play worse and your real return drops.
RTP is a long-run average, not a session promise
A 96% RTP does not mean you'll get $96 back from $100 tonight. It's an average over hundreds of thousands of rounds. In any single session you might double your money or lose it all — that scatter is variance. RTP only describes where the average lands once variance washes out, and that average is always below 100%.
A higher RTP doesn't make a game beatable
Switching from a 92% game to a 99.5% game doesn't flip the math in your favor — it just makes your bankroll bleed slower, so you get more entertainment per dollar. The house still wins over time. You can watch exactly how fast different RTPs grind a bankroll down in our interactive house-edge model.
Reading published RTPs
Treat advertised RTPs with care: slot RTPs are often given as a range and are set by the operator; table-game RTPs frequently assume optimal strategy; and a game's volatility can differ wildly even at the same RTP. RTP is a useful comparison number — just not a winning one.
How this simulation works
- Rules modeled
- RTP shown as 100% − house edge for each game.
- Mathematical basis
- House edges from our sourced presets: roulette exact (1/37 = 2.70%, 2/38 = 5.26%), blackjack ≈0.5% (basic strategy, from our separately reviewed solver — depends on the rule set), and an illustrative 96%-RTP slot (not a real machine). RTP = 100% − edge.
- Validation
- Figures derive directly from the same unit-tested presets used by the house-edge model.
- Last reviewed
- Uses the house-edge model presets; the model was independently reviewed across five rounds (2026-06-22), with every reported finding addressed.
