Run thousands of spins. Watch your bankroll curve. Find out why progressions break.
For the maths behind these numbers, work through house edge math, why progressions fail, and bankroll and variance in the Mayfair Casino School. The simulator is where you watch the theory play itself out.
Two modes. Autopilot configures a betting system, a base unit, a bankroll, and a number of spins, then runs that session thousands of times and shows the distribution of outcomes. Manual play hands you chips and a felt and lets you place bets one spin at a time. Same underlying engine; very different feel.
The Monte Carlo runs use a xoshiro256** pseudo-random number generator seeded from crypto.getRandomValues. Period is around 2¹⁹⁸, which is comfortably more than you need. Everything is computed in your browser. Nothing leaves the device.
It will not produce a roulette system that profits in the long run. None exists. Roulette has a fixed negative expected value on every wager. 2.70% on European single-zero, 5.26% on American double-zero. 1.35% on French even-money under la partage. No bet sequencing changes those numbers. The progressions only redistribute outcomes: lower median, fatter tails. The autopilot's Compare all four systems button puts them next to each other so you can see this for yourself.
