Happy Salmon is a simple, ultra-fast, very silly card game. There are no turns. Players call out the action shown on their cards as fast as they can. When two players have a match, they celebrate by performing the action. Actions include the classic "High 5", the unifying "Pound It", the frantic "Switcheroo", and the delightful and bizarre "Happy Salmon".
Each time a player celebrates a match, they quickly discard a card. The first person to get rid of all their cards wins.
