Quick Answer
Return to Player (RTP) is a theoretical percentage that represents how much of the total money wagered on a game is paid back to players over time. A 96% RTP means that for every $100 wagered collectively, $96 is returned to players. The remaining $4 is the house's theoretical profit — the house edge.
Key Facts
- RTP = the percentage of wagers returned to players over time
- House Edge = 100% − RTP
- Higher RTP = better for the player
- 100% RTP = no house edge
- RTP is theoretical, not a guarantee for individual sessions
Understanding the Calculation
RTP is calculated over an extremely large number of game rounds — often millions. It is not a prediction of what will happen in your session. It is a statistical property of the game engine.
Formula: RTP = (Total Player Winnings ÷ Total Player Wagers) × 100
Example: If a slot pays out $950,000 across $1,000,000 in wagers:
- RTP = (950,000 ÷ 1,000,000) × 100 = 95%
RTP Across Different Game Types
| Game Type | Typical RTP Range |
|---|---|
| Classic Slots | 92% – 96% |
| Video Slots | 94% – 98% |
| Crypto Dice | 98% – 99.5% |
| Crash Games | 95% – 99% |
| Blackjack (optimal) | 99% – 99.5% |
| Duel Originals (with DUEL5) | 100% |
What 100% RTP Means
A 100% RTP game has no theoretical house edge. Over an infinite number of plays, the game returns the equivalent of everything wagered. This does not mean you will never lose — variance still causes short-term fluctuations — but the platform has no long-run mathematical advantage.
RTP vs House Edge
These two concepts are the same thing viewed from different angles:
- House Edge: The platform's advantage — what they keep theoretically
- RTP: The player's return — what players receive theoretically
A game with 97.3% RTP has a 2.7% house edge. A game with 100% RTP has a 0% house edge.
Variance and RTP
Variance (also called volatility) describes how much individual session results deviate from the theoretical RTP. A high-variance slot might have the same RTP as a low-variance one, but the distribution of wins looks very different:
- Low variance: Frequent small wins, results close to RTP in shorter sessions
- High variance: Infrequent large wins, results can deviate significantly from RTP in shorter sessions
Understanding variance helps explain why RTP alone does not determine your experience.
Why RTP Matters When Choosing Where to Play
When selecting games, a higher RTP means you lose less per dollar wagered in the theoretical long run. Combined with rakeback, which returns a portion of even the house edge that remains, choosing high-RTP games and using a code like DUEL5 represents the most efficient strategy for minimising theoretical losses.
