Simulates many independent bettors making many sequential bets under a chosen sizing rule. The ensemble average and the median (typical single path) visibly diverge — the average is not what any one bettor actually experiences.
What the sliders and boxes above do: "Win probability" sets how often you believe the bet wins — right now it's 55 out of every 100 tries. "Bets per bettor" is how many times in a row someone keeps betting (like a whole season), and "Simulated bettors" is how many imaginary people the app tests this on at once, to see the range of what could happen. Change any of these and the chart and bars below redraw immediately.
Every faint line is one simulated person's money over time, betting the sizing rule you picked above. Clicking a different rule (Full Kelly / ½ Kelly / Flat / 2× Kelly) re-runs the whole simulation and redraws this chart for that rule.
Ruin = bankroll ever dropping to ≤1% of starting bankroll during the simulation.
