Roulette Simulator

Complete Roulette Simulator Suite

Test all major betting systems in one comprehensive simulator. Run Monte Carlo simulations to understand why no betting system can overcome the mathematical house edge in roulette.

🎯 All Systems Included

Test all 6 major betting systems: Martingale, Fibonacci, D'Alembert, Labouchere, Oscar's Grind, and Paroli in detailed simulations.

📊 Monte Carlo Analysis

Run up to 1 million sessions to get statistically significant results showing long-term performance of each system.

🧮 Educational Purpose

Understand why all betting systems fail mathematically while learning about probability, statistics, and risk management.

Martingale Simulator

Dedicated Page

Martingale Monte Carlo Simulation

Martingale Progression Example:

Loss 1: $5Loss 2: $10Loss 3: $20Loss 4: $40Loss 5: $80Loss 6: $160Loss 7: $320Loss 8: $640Loss 9: $1280Loss 10: $2560

Total at risk after 10 losses: $5115

Fibonacci Simulator

Dedicated Page

Fibonacci Monte Carlo Simulation

Fibonacci Sequence Example:

11235813213455

Move forward 1 position on loss, back 2 positions on win

Roulette Type

D'Alembert Simulator

Dedicated Page

D'Alembert Monte Carlo Simulation

D'Alembert Strategy:

Increase your bet by one unit after a loss, decrease by one unit after a win. This system aims to balance wins and losses over time.

Labouchere Simulator

Dedicated Page

Labouchere Monte Carlo Simulation

Labouchere Strategy:

Start with sequence: [1, 2, 3, 4, 5]. Bet sum of first and last numbers. Win: remove those numbers. Loss: add bet amount to end. Target: $75 per sequence.

Current sequence profit target: $75

Roulette Type

Oscar's Grind Simulator

Dedicated Page

Oscar's Grind Monte Carlo Simulation

Oscar's Grind Strategy:

Keep same bet after each loss, increase bet by one unit after wins (until target reached). Complete a cycle when you reach $20 profit, then reset to base bet. Conservative progression system.

Roulette Type

Paroli Simulator

Dedicated Page

Paroli Monte Carlo Simulation

Paroli Strategy:

Double your bet after each win for 3 consecutive wins, then reset to base bet. This positive progression system aims to capitalize on winning streaks.

Cycle: Win 1: $5Win 2: $10Win 3: $20

The Mathematical Reality

Why All Systems Fail:

  • • European roulette has 2.7% house edge on every spin
  • • American roulette has 5.26% house edge on every spin
  • • No betting pattern can change these mathematical facts
  • • House edge ensures long-term losses regardless of system

What These Simulators Teach:

  • • Short-term variance can create illusion of effectiveness
  • • Progressive systems increase risk without increasing returns
  • • Table limits and bankroll constraints prevent "sure" systems
  • • Education and understanding beat false hope
