The Bet Tab
The Bet tab is the roulette table. Click any bet option — a number, 0, 00, or one of the outside bets along the rail — and a dialog explains the true odds of that option, reports how often it has actually occurred on this wheel so far, and asks how many chips to stake. Placed chips appear as gold badges on the felt. Press Spin (or Enter) to set the wheel in motion.
Quick bets: scroll the mouse wheel over any bet option to adjust it without the dialog — scroll up to add a chip, down to remove one. You can spread chips across as many options as you like; each is settled independently.
Spin(s) per press controls batch size. At 1, every press of Spin is a single spin. Raise it to run a simulation: your placed bets settle against the first spin of the batch, and the remaining spins run bet-free to build the wheel's statistics. Press Esc or Stop to end a long run early.
Current Result shows the winning number and every category it belongs to — its color, even or odd, high or low, dozen, and column. Previous Bets logs each settled bet and what it won or lost. You start with 20 chips; if you go bust, Player Stats offers a buy-back.
The Stats Tab
Every spin — manual, batch, or strategy race — updates statistics for all 50 bet options on one shared wheel. For each option you see its Occurrences (spins that matched it), Percentage Wins, and the Highest Consecutive Wins and Losses ever recorded — the streaks that make and break betting systems.
The Outside tab covers the even-money and 2-to-1 options; Inside covers 0, 00, and the thirty-six numbers. View Real-Time repaints the table as a batch runs; Faster waits until the batch finishes and delivers the highest spins per second. Reset clears the wheel's entire history.
Run enough spins and watch each number converge toward 1 in 38 — about 2.63% — no matter what the last hundred spins looked like. That convergence is the whole lesson of this app.
The Strategy Tab
Strategies are automated players. Add them to the roster, set the spin count and each entrant's starting chips, and press Race. Every racer bets against the identical sequence of spins — one shared wheel — so when two bankroll curves diverge, the cause is pure strategy, never luck. The same losing streak that ruins one system is survived, or exploited, by another, and you watch it happen on the chart.
The chart draws one line per strategy against the dashed starting-bankroll line. The leaderboard ranks racers by final chips — survivors above the busted — and reports each one's Peak, Max Drawdown (the deepest fall from a peak), and the spin its bankroll hit zero. A racer that can't cover its intended bet goes all-in with what remains; at zero chips it is out of the race.
Ten classic systems are built in — Martingale, Grand Martingale, Paroli (the reverse Martingale), D'Alembert, Fibonacci, Labouchère, Oscar's Grind, the James Bond spread, Andrucci, and Flat Bet, the honest baseline every system must beat. Each one describes itself in the Add Strategy dialog. To invent your own, Custom Progression is a rule builder: pick any bet option, a base bet, and what happens to the bet after each win or loss — enough to express most systems ever devised.
Custom Code is for programmers: write a JavaScript function body that runs
before every spin and returns the bets to place as [[betOptionIndex, chips], ...].
It receives ctx = { chips, spin, lastWon, lastNet, lastResult } — only what a real
bettor could know. Bet option indexes: 0–36 the numbers, 37 = 00,
38 Red, 39 Black, 40 Even, 41 Odd,
42 = 1 to 18, 43 = 19 to 36, 44–46 the dozens,
47–49 the columns.
Shortcuts
Enter spins. Esc stops a running simulation or closes any dialog. The mouse wheel over a bet option adds or removes chips. Everything else is a click.
The Odds
On a double-zero wheel every bet option carries the same house edge: payoffs are set as if the wheel had 36 pockets, but it has 38, so the expected loss is 2/38 — about 5.26% of every chip wagered. No progression, streak, or system changes that expectation; it only reshapes the ride. Don't take this page's word for it: simulate a million spins on the Stats tab, race the strategies against each other, and watch the math assert itself.
