The colour game: a ball from 0 to 9 is drawn, and every number has a colour. 1, 3, 7 and 9 are green, 2, 4, 6 and 8 are red, 5 is green and violet, 0 is red and violet. Bet on a colour, on a number, or on big (5 to 9) or small (0 to 4), and put chips on as many as you like for one draw.

Pick a chip under the board and tap the cells to place it; press and hold (or right-click) to take one off, Ctrl+Z to undo. A colour pays twice your bet (one and a half on its violet number), violet four and a half times, a number nine times, big or small twice. As in the colour-prediction apps, a 2% fee comes off every bet first. Auto repeats your bets draw after draw.

Draw instantly, or switch the stage to 30 s periods, as in the apps: each period counts down, your chips go on while it runs and are drawn when it reaches 0, and betting closes for its last 5 seconds. Every period has its number, and it's your own: the same payouts, nobody else at the table.

Every draw comes from your own provably fair seed pair the moment your bet is placed, never before. Check any draw on the Provably fair page.
