About Troggu, from BoardGameGeek:

Troggu, also known as Trogga or Tappä, is a form of Tarot played in a few villages in the German speaking part of canton Wallis in Switzerland (from pagat). It is a must-follow, must-trump trick taking that can be played by 3-8 players. The game is played using 68 cards, omitting 4 cards from each suit. Each card have point value associated with it. Fool, Trump 1, Trump 21, and King=5, Queen=4, Cavalier=3, Jack=2, all other card=1. You bid if you can take more than half the points(58 points out of 114) and became a Tapp. Then play the standard must-trump trick taking game. If there are 7 or more players, the Tapp can choose his partner as well.
