Free roulette calculator, rebuilt Racetrack and call bets Place Voisins du Zero, Tiers, Orphelins and Jeu Zero in one tap, with the exact chip layout each call bet actually uses. A neighbours control covers any number plus the pockets either side of it on the wheel, and every button shows what the placement costs before you commit. A felt that works like a real mat Tap between four numbers for a corner, on a line for a split, anywhere on the mat for the bet that spot really is. Chips are drawn where you placed them, at the value you placed. See the whole spread The outcome chart shows how often every result lands for the bets on your table, next to your coverage and expected value. Plan your stakes before you sit down The progression calculator covers Martingale, D'Alembert and Fibonacci, six calculated presets, or your own sequence. It shows what each step stakes, what the sequence puts at risk, and when a step can no longer cover what came before. A thousand sessions, not one lucky one The simulator plays your bets a thousand times and shows where the sessions landed: the middle one, the best and worst tenth, and how often the bankroll ran out. A single session is still there underneath. Sign in with your email Email sign in now works, and your board is saved and offered back when you return.
