The roulette

Roulette is a game at the Mauville Game Corner in Pokémon Ruby, Sapphire, and Emerald. It is based on the game roulette, which can be found at many real-world casinos.

## Play

The roulette wheel

The roulette wheel has twelve spaces. Each space has one of three colors and one of four Pokémon: yellow, green, and purple; Makuhita, Azurill, Skitty, and Wynaut). By betting where a ball will land, players can win Coins.

Bets can be placed in three different ways: by single space, by color, or by Pokémon. Winning a bet by space returns twelve times as much as was originally bet, by Pokémon yields four times the amount bet, and winning by color gives three times as much. Each ball remains on the wheel until the wheel is reset, once six balls have been put into play. This changes the odds for future bets, as only one ball can fit into each space.

A bet on a Pokémon or color increases its payout when some of the possibilities are taken off the board. The multiplier of the payout is always equal to 12 divided by the number of empty spaces in the bet type. For example, if a bet has already landed on a Wynaut, that row will have a ×6 multiplier instead of the usual ×4 multiplier.

There are two roulette wheels, with one having a wager of 1 coin, and the other having a wager of 3 coins. On the Game Corner's Service Day, the 3-coin table has a special rate of a 6 coin wager instead.

Sometimes the ball may get stuck between two balls which have already settled. When this happens, either a Shroomish will drop down, causing the ball to fly up into the air and land in another spot, or a Taillow will pick it up and, after hovering with it for a bit, drop it into another spot.

### Strategy and probabilities

Because the payouts are calculated based on an empty board, the odds favor the player as the more balls fill the roulette wheel. For example, on an empty board, the payout of a single space (×12) matches its probability (1/12). After five spins, the payout remains the same, but the probability of a win increases to 1/7, giving the player a 71% edge on the final spin. This advantage (30.64% on average) in odds favors the player in the long run, but the small bet amounts inhibit winning fortunes quickly.
