YADOKARICK is a trick-taking game in which 1-7 players try to find the right size shell for their hermit crab from beach detritus.
The game consists of two suits, and in addition to a suit and rank, each card has a "shell size". During the game, the lowest card played to a trick will be able to adjust the target shell size up or down. The highest card of each color played to a trick will take the cards of that color with the largest size and add to their hermit crab. The bodies have a maximum size and may have a "roof" card added.
At the end of a hand, positive points are earned for total shell sizes less than or equal to the target, and points are lost for shells that exceed the size or for players who added too many cards to their shell. The player with the most points wins.
