Very good. No visual gadgets, concentration on the play of the game, which is much appreciated. Very fast discards, so sometimes it's not sure which tile exactly can be called, but that's a matter of customisation. First time I played with more than three red fives, but even that's a matter of customisation. Highly recommendable for everyone knowing basic japanese mahjong.
