About
Honest numbers for every roulette system
SystemAnalyzer tests roulette betting systems the same way, every time — so you can see what a system really does before you ever try it at a table.
What we do
Roulette systems are everywhere: on YouTube, in forums, in books. Most come with a story and a few lucky sessions. We take the rules exactly as they are presented, build every level on the table, and run them through the same Monte Carlo simulation: 10,000 players, each starting with the system's bankroll, playing until they reach the goal or go bust — at +$50, +$100 and +$200, on the European and the American wheel. An endurance test shows how the bankroll holds up over a fixed number of spins.
You get the win rate, the bust risk, the average number of spins and the average result — and you can see every level on the table, play the system spin by spin, or build your own. How we test explains every number.
What we don't do
- No real-money gambling. Nothing on this site takes a bet or a deposit. Play it uses simulated spins.
- No promises. No system beats the house edge — 2.7% on a European wheel, 5.26% on an American one. A high win rate at a small goal always comes with a rare but large loss.
- No paid rankings. Every system is tested with the same method. Nobody can pay to change a number.
- No casino links. We don't link to casinos, show casino ads or earn anything from casinos — ever.
Where the systems come from
Most systems come from videos and articles, credited on their page. Players can also build a system in our System Builder and submit it; we simulate it on both wheels before it is added to the catalog.
How the site is funded
Everything on the system pages, the 100 Club, The Lab, Free Roulette and Play is free. The site is paid for by Pro, which lets you test any system with your own bankroll, unit size, goal and stop rules. We have no casino partners and take no commission from any gambling operator, so nothing affects a simulation, a rating or the order of the systems. If you do play for real money, only do it where it is legal for you, and only if you are 18 or older — see Responsible gambling.
Who is behind it
