Monte Carlo · 1,000 players · American & European roulette
Every strategy analyzed, simulated, and compared. No gambling — pure math.
Ranked by win rate at each target level across all 1,000-player simulations.
Every system on this site goes through the same process before a single number appears on a card.
We simulate 1,000 independent players for each system, each starting with the system's recommended bankroll. Every player spins until they either reach the session goal or lose their entire bankroll. No player influences another — each run is fully independent.
Each system is tested at three profit targets: +$50, +$100 and +$200. A lower target means fewer spins and less exposure to losing streaks. We show all three so you can choose the risk level that fits your session.
Where data is available, we test on both European roulette (single zero, 37 pockets) and American roulette (double zero, 38 pockets). The extra zero in American roulette raises the house edge from 2.7% to 5.26% — a meaningful difference over a long session.
Most strategy videos are recorded on a European wheel (single zero). We always run our simulations on both wheel types regardless — because the math applies to both, and many players have access to American tables only.
For systems that do not include 0 or 00 in their bets (such as pure color, dozen or street systems), the only difference between European and American is the extra losing pocket. If 0 and 00 are not part of the system, our American simulation gives you an honest picture of what the extra zero costs you in practice.
Win rate is the percentage of the 1,000 simulated players who reached the profit goal before going bust. Avg spins is how long a typical session lasted. Avg net is the average dollar outcome across all 1,000 players — winners and losers combined.
Each system receives an editorial assessment based on three factors: win rate at +$50 goal, required bankroll relative to base bet size, and simplicity of the rules at the table. A system rated playable clears a 70%+ win rate at +$50 and has clear, followable rules. This is our opinion — not a guarantee.
No strategy eliminates the house edge. Every number on every spin is an independent random event — the wheel has no memory. A system that wins 85% of the time in simulation will still fail 15% of the time, and those failures can wipe out many previous wins in a single session. Never bet money you cannot afford to lose.
