How it works. Each player faces four calls: Red or Black, Higher or Lower, Inside or Outside, then guess the Suit. Get one wrong and you drink — later calls cost more sips. Whoever drinks the most rides the bus at the end: solo, they face all four calls again — Red/Black, Higher/Lower, Inside/Outside, then the Suit — and must clear all four in a row to get off. In Classic, a miss drops you back one level; in Extreme, any miss sends you right back to Level 1. Aces are high. Equal counts as wrong.
