🧪 Strategy Lab

Pick a coverage strategy, then simulate thousands of spins instantly. This is where we settle the bet: does covering more of the board actually beat the house?

Board coverage: 0%
Why no strategy can win (the actual math)
  • A winning straight-up pays 35:1, but a fair payout would be 36:1 (37 numbers on a EU wheel). That missing 1 is the house edge.
  • Every bet — straight, split, red/black, dozen — carries the same −2.70% expected value on a EU wheel. Spreading chips over 80% of the board just bundles a bunch of −2.70% bets together.
  • Covering more numbers lowers your variance (smoother ride) but never changes the average. You win small often and lose big occasionally — netting the same loss.
  • Past spins don't predict future ones. There is no pattern for AI to learn — the wheel has no memory.
  • The only real edge ever found came from physics (biased wheels, dealer signature, computer-timed ball speed) — not betting patterns. Modern wheels and electronic RNGs close those gaps.
