The Strategy Lab

Run the math.

Describe any staking system, hand it a bankroll, and watch it face double-zero roulette — the same odds, spin after spin, with nothing hidden.

This is a simulator for education — it proves no system beats the edge. Play for fun, never for rent money.

SEED — same seed → same run

Model: American double-zero roulette, even-money outside bets — win probability 18/38 (47.37%) per spin, house edge 5.26%. Table max is 100× your base bet. Bust means the system demands a bet your bankroll can’t cover. Seeded RNG (mulberry32), so every run is reproducible.

Run a simulation to draw the bankroll curve.
