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:

Blackjack (basic strategy)
99.50% RTP
0.50% edge
European roulette
97.30% RTP
2.70% edge
American roulette
94.74% RTP
5.26% edge
Illustrative 96% RTP slot
96.00% RTP
4.00% edge
90%magnified RTP scale100%

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.
