I simulated 98 roulette systems with 10,000 players each – here are the results

Hello everyone!

I've long been curious about whether the roulette systems you see on YouTube actually work, so I built a tool that plays each system bet-by-bet with 10,000 simulated players.

Some things that surprised me:

• No system beats the house edge – everyone loses money on average, even those who hit the target 95% of the time.

• The best were not the most advanced systems. Simple progressions like Martingale and "Double Up Dozens" came closest to the mathematical ceiling for how often you can reach a goal.

• Many "never lose" systems from YouTube lose their entire bankroll about every 10 sessions. They look good in a 15 minute video but not over thousands of sessions.

• Coverage is tricky: a 30-number system can be worse than one with 18, if the "wins" on half of the numbers are actually losses or break even.

I rank the systems by how close they come to the best possible result with the same bankroll, rather than just the chance of winning – otherwise the system with the largest bankroll always wins.

Full disclosure: it's my own site, it's free and without casino links or bonus codes. The ranking is here if anyone wants to check their favorite system:

What system do you play yourself? Let me know if there's anything missing and I'll test it.

That’s actually an interesting way to look at roulette systems, especially when you test them over thousands of simulated sessions instead of judging them from a few successful runs.

I also appreciate that you were transparent about the website being your own.

Just one small reminder for future posts: please avoid including links to your own websites or projects, even if the site itself is free and doesn’t contain casino or bonus links. We try to keep self-promotion and advertising off the forum.

You’re absolutely welcome to discuss the results, methodology and different roulette systems here, just without the external promotional links, so we don’t have to moderate the posts later.
