Monte Carlo Simulation
Simulate 3,600 tickets across 3,000 trials to see realistic outcomes.
Visualizing the Odds
Each dot = 1 ticket out of 10,000. The highlighted dot(s) represent winning.(Actual odds are 1 in 20,000,000 — even harder than shown!)
Can you find the single red dot? That is your chance of winning.
