About KUSOGE TRICK, from BoardGameGeek:

KUSOGE TRICK is a Hearts-like trick-taking game where the rules for scoring change with each round. At the end of the round, you receive chips for negative points. There are two types of the negative point chips: 1 point and 5 points. The player with fewest negative chips wins. (Note :it is not the total value of the negative points.) This game was inspired by an episode of the old toilet situation in Hokkaido, Japan, told by a personality on the Japanese web radio program “GAYA Radio”.
