To win, spin the wheel and hit any one of the 5 winning patterns shown above while avoiding black. Hitting black at any time results in a loss.

A game consists of at most 5 spins of the wheel. The wheel consists of 5 colored slices (blue, red, yellow, green, and purple) and 1 black slice. Black is not considered a color.

Before a game begins, the player decides on a bet amount. The game begins when the player presses the "New game" button and the wheel is drawn. The bet amount is charged to the player as the cost of the game and is non-refundable.

The sizes of the wheel's colored slices change for every game but remains constant *during* a game. The purple slice is fixed at 1% of the wheel. The black slice size is fixed at 16% of the wheel at all times. Each of the other slices (blue, red, yellow, and green) is never less than 15% of the wheel.

Hitting black at any time ends the current game and results in a loss with no payout.

Hitting any of the winning patterns immediately ends to game with a payout. The winning patterns are:

**King slice:** Hit the purple slice.
**4 colors in 4 spins:** Hit each of the four colors in succession (that is, over a total of 4 spins).
**3 in a row:** Hit the same color in 3 consecutive spins.
**3 out of 5:** Hit the same color in any 3 of the previous 5 spins. Note that this winning pattern can only be achieved after the wheel has been spun at least 5 times.
**5 spins, any color:** Spin the wheel 5 times without hitting black.

In case a spin results in more than one winning pattern being hit, the one with the highest payout will be awarded.

The maximum bet is 1 BTC. The minimum bet is 0.0001 BTC.
