How we test

Every system on this site goes through the same process before a single number appears on a card.

🎲

Monte Carlo simulation

We simulate 10,000 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.

🎯

Three goal levels

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.

🌍

Both wheel types

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.

📹

Videos vs. our simulations

Most strategy videos are recorded on a European wheel (single zero). Our simulations match the wheel type the system is designed for — European or American — so the numbers reflect how the strategy actually plays on that table.

For systems that do not include 0 or 00 in their bets (such as pure color, dozen or street systems), the only practical difference between the two wheels is the extra losing pocket in American roulette, which raises the house edge from 2.7% to 5.26%.

📊

What the numbers mean

Win rate is the percentage of the 10,000 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 10,000 players — winners and losers combined.

✅

Our playability rating

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.

⏱

Endurance test

Beyond the Monte Carlo results, we run a separate endurance test: 1,000 players play for a fixed number of spins — 50, 100, and 200 — without a profit target. We track who still has money at the end (survival rate) and what their bankroll looks like (median bankroll). This tells you how a system holds up over a longer session, not just whether it can hit a short-term goal.

⚠️

Roulette is a game of chance

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.
