In more detail, a Buffalo bet combines a hardway bet (which means the dice will land on doubles, like two 3s for a 6) and a bet that a 7 will be rolled. It covers every possible outcome for the dice that results in either a hardway number or a 7. Players who make this bet are wagering that these specific outcomes will occur before a 7 appears (for hardway numbers) or simply betting on 7 directly.
Buffalo Example
For example, if a player places a Buffalo bet, they might win if a hard 6 (two 3s) or 7 is rolled, but lose if any other combination appears.
