Thirty-seven pockets and one green one
The wheel on FakeRainbet is the European single-zero wheel: pockets numbered 1 to 36, alternating red and black, plus a single green zero. Thirty-seven pockets in total, one ball, and a layout that has barely changed in two centuries. You place chips anywhere on the table, the ball is released, and it settles into exactly one pocket. Every bet that covers that pocket is paid, and every bet that does not is collected. There is nothing hidden and nothing to interpret.
What makes the roulette casino game endlessly written about is not its complexity, because it has almost none, but the sheer variety of ways it lets you express the same underlying wager. You can put everything on one number, or spread chips across half the table, or build an elaborate pattern of splits and corners that covers most of the board. All of these feel like different games. Mathematically, they are the same game wearing different costumes, and understanding why is the most useful thing this page can give you.
