Casino games/Roulette

Roulette is a casino game found in many video games as a minigame used to gamble in-game currency. They will typically be identical to real-world examples, using either the European single-0 or the American double-0 games.

In roulette, the house advantage is explicitly shown by the presence of the green 0 (and 00 if present); odds for each bet are calculated assuming only the numbers 1-36 exist, and although players can bet on the house numbers, it is equivalent to treating different numbers as house numbers instead. As such, there is generally no strategy involved in roulette, as all bets return the same RTP. However, there are exceptions, especially if variant rules are in play.

Odds
Single-0 roulette wheels have 37 slots in which the ball can land; 1 to 36, plus 0; double-0 adds a 00 to total 38 slots.

Numbers 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, and 36 are red; numbers 2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 35 are black; numbers 0 (and 00 if present) are green. If the table uses la partage or en prison rules, always bet on 1-18, 19-36, odd, even, red, or black; otherwise, all bets are equal (aside from the basket in double-0 roulette, which should never be played).
