Free roulette simulator — with a live edge meter
Every simulator lets you spin. This one also tells you the truth while you do it: a live meter tracks your realized house edge against the wheel's theoretical 2.70%, and a systems autopilot lets you run Martingale, Paroli, D'Alembert or Fibonacci hands-free — and watch what a million-session study looks like, one bankroll at a time. Three wheels, real la partage on French, no sign-up, nothing leaves your browser.⚙ computed
🤖 Systems autopilot — bets red automatically, you watch the math.
Why an "honest mode"?
Casinos show you a balance. We show you the price. Over a short session your realized edge swings wildly — that's variance, and it's exactly what makes systems feel like they work. Keep spinning (or hit 20× turbo on the autopilot) and watch the meter walk home to 2.70% like it always does. Then read what a million sessions look like.
To remove a bet: pick the − chip and tap it (or shift-click). Preferences stay in your browser only.

Frequently asked
Is this roulette simulator really free?
Completely — no sign-up, no deposit, no download. The balance is play money and everything runs in your browser.
Does the French wheel here actually apply la partage?
Yes — land on zero with an even-money bet and half your stake comes back, exactly as the 1.35% math requires. Most free simulators skip this; we consider it the whole point of the French game.
What is the edge meter showing?
Realized house edge = your net loss divided by everything you have wagered. Early on it swings with luck; over hundreds of spins it converges to the wheel’s theoretical number. Watching that happen teaches more than any article.
Can I test betting systems here?
Switch on the autopilot: it plays Martingale, Paroli, D’Alembert, Fibonacci or flat on red automatically at up to 20× speed, with the meter running. Every system page on this site links straight into it.
