Roulette, proven.
Roulette has a fixed price: 2.70% of everything you wager on a European wheel, 5.26% on American, 1.35% on French even-money bets. No system changes that number — we ran 1,000,000 Martingale sessions to check, and the wheel kept exactly its 2.70%. What systems do change is how you lose. This site shows you all of it, with the receipts.⚙ computed

Frequently asked
Can any betting system beat roulette?
No. We simulated fourteen systems over 200,000–1,000,000 sessions each: every one paid the house its exact edge (2.69–2.78% realized on a 2.70% wheel). Systems change the distribution of outcomes — bust rates ranged from 0% to 94% — but never the price.
Which roulette game has the best odds?
French roulette with la partage: even-money bets cost 1.35% instead of 2.70% (European) or 5.26% (American). If you play, that is the whole strategy in one sentence.
