Challenging trick-taking game. Depending on the amount of players, each player needs to discard 2 or 3 hand cards to secretly bid how many tricks he would take. A successful bid gives him bonus points. Players can choose to do additional bids by showing their bid or even their complete hand in order to score even more bonus points. However, if they fail, the points go to their opponents.
Besides 36 cards in 4 suits, the game contains a butterfly, which causes confusion and surprise.
