This is a sushi-themed mahjong-like card game for two. At the start of the game each player is dealt eleven cards. Five of these are put face down as your "prep", and then you each take turns discarding cards. To win you have to make a hand of either two sets of three-of-a-kind or three pairs by combining your prep and your opponent's discard. There's a catch, though - like in mahjong, you can't win with a discard that you've already discarded yourself. The points for winning hands also depend on what sushi you use in the sets, so will you try for big points or go for a lower-scoring hand your opponent is more likely to discard? —user summary
