寝返りふれんず (Negaeri Friends)

Negaeri Friends is a trick-taking game where the suits are visible on the rear of the cards and the trump is randomly changed each trick. When a player follows suit, they can choose to play face up or face down - but a person playing off suit must play face up. The winner of a trick only collects the face up cards, with face down cards moving to a face down pile in front of the person who played it. At the end of the hand, all cards won in tricks are worth 1 point. Face down cards are revealed and the person with the highest sum of ranks in each suit earns 2 points. The person with the most points after a series of rounds wins.
