You are a whale. More accurately, you are a group of Baleen whales and you are hungry for Krill.
In Go For The Krill, 2 - 6 players control a group of whales made up of a hand of cards numbered 1 - 10, a squid card, and a penguin card. Your goal is to play a card each round to consume a school of Plankton (or the more valuable Krill) cards that correspond to the numbered whale card you played. If two or more players play the same number in a single round, the cards are moot and the players gets nothing!
Players place a single whale card in front of them face down. All whale cards are revealed simultaneously and scored. After 12 rounds, players total the number of Krill and Plankton cards and the player with the most points, wins.
