Betting systems debunked
Famous systems, same ending.
D'Alembert, Fibonacci, Labouchere, Paroli — each promises a way around the odds. Run 2,000 simulated sessions of any of them and watch the promise dissolve.
The idea
A system reshapes variance, not the sign.
Every spin carries the same house edge, and stacking spins only stacks that edge. A system can make most sessions end in a small profit — which is exactly the trap, because the rare bad run quietly takes all of it back, and more.
Put the system to the test
We simulate 2,000 roulette sessions. See how they end.
You raise one unit on a loss, lower one on a win. It promises slow, steady progress.
