User summary オトーリバース (OTOOREVERSE) is a card game with a theme of drinking race. In a drinking party in Japan, 'reverse' means "to reverse what you have ingested". It is a mild expression of 'vomit'. At the beginning of the game, you are assigned a character, who has their own alcohol capacity and beverage preferences. Their favorite beverage's alcohol counts zero, and hated one counts double toward their capacity. Each turn, you may choose to quaff a beverage (draw a card), and if the total amount of alcohol exceeds your character's capacity, the character 'reverses' and you are out of the round with no victory points. You should stop drinking before your character 'reverses'. When any character would quaff a beverage (after drawing a card but before resolving it), you may make an 'alhara' (alcohol harassment) to force any character (including yours) to quaff that beverage. You have limited times of 'alhara' attempts. At the end of round, each non-'reversed' player gains victory points according to beverages their character has quaffed. After several rounds, the highest scorer wins the game.
