What Is RTP (Return to Player)?
Return to Player (RTP) is a percentage that describes how much of the total money wagered on a game is paid back to players over many thousands of bets. It's the inverse of the house edge.
📊 RTP Formula
- RTP = Total Returned to Players ÷ Total Wagered × 100%
- 96% RTP = Casino keeps 4% (4% house edge)
- 99% RTP = Casino keeps 1% (1% house edge)
- 100% RTP = Casino keeps 0% (0% house edge)

How Provably Fair Guarantees 100% RTP
Duel achieves 100% RTP through provably fair technology combined with mathematically designed game algorithms. The game outcomes are generated using cryptographic seed combinations that produce statistically fair results. Players can independently verify every result.
Without provably fair technology, a casino could theoretically manipulate RTP. With cryptographic verification, manipulation is mathematically impossible — the outcome is determined before the bet resolves.
