What Is the House Edge?
The house edge is the casino's built-in mathematical profit margin. Every casino game is designed so that, over time, the casino keeps a small percentage of all money wagered. This is how casinos stay profitable.
| Game | Typical House Edge | Casino Keeps per $100 Bet |
|---|---|---|
| Duel Originals + DUEL5 | 0% | $0.00 |
| European Roulette | 2.70% | $2.70 |
| American Roulette | 5.26% | $5.26 |
| Blackjack (perfect strategy) | 0.5–1% | $0.50–$1.00 |
| Baccarat | 1.06–1.24% | $1.06–$1.24 |
| Video Slots (online) | 4–6% | $4–$6 |
| Land Casino Slots | 8–15% | $8–$15 |
| Keno | 20–40% | $20–$40 |
The Mathematics of Zero House Edge
In a game with a 2% house edge, for every $100 bet you place, the casino expects to earn $2 over time. After 1,000 bets at $10 each ($10,000 wagered), you'd expect to lose $200 purely from the house edge.
At zero house edge, this loss is eliminated. Your expected outcome per $100 wagered is exactly $100 returned. The only source of wins and losses is variance — the natural randomness of game outcomes.
Zero House Edge + 50% Rakeback = Unique Expected Value
The combination of zero house edge and 50% rakeback on Duel creates a unique situation:
- Zero house edge means no theoretical loss from the game design
- 50% rakeback means any variance-driven losses are 50% recovered
- Together: losing days are halved in impact, winning days keep full profits
Zero House Edge FAQ
- Zero house edge means the casino takes no mathematical cut from wagers. Games run at true statistical odds. The expected value per bet is $1 for every $1 wagered. On Duel Originals with DUEL5, this is exactly what you get.
- Duel offers zero house edge on Originals through provably fair game algorithms combined with the DUEL5 referral code benefit. The games are mathematically designed to run at 100% RTP, verified cryptographically by players.
- Yes. 100% RTP and zero house edge are mathematically equivalent. 100% RTP means the game returns 100% of wagered funds over time. Zero house edge means the casino's built-in advantage is 0%. Both describe the same condition.
- No. Zero house edge refers to the long-run mathematical expectation, not individual session outcomes. You will still experience wins and losses due to variance. Over thousands of bets, your total returns converge toward 100% of your total wagers.
- With DUEL5, all Duel Originals operate at zero house edge: Crash, Mines, Plinko, Dice, Blackjack (Duel's version), and Roulette (Duel's version). Third-party slots do not benefit from zero house edge.
