As Good as Mahjong Gets
To be honest, Mahjong isn't the most interesting game ever, but its a good, entertaining puzzle when you want to pass some time. This game in particular can keep you playing for ages with the loads of different levels there are to play.
However, maybe some nice, calm background music would really give it a peaceful atmosphere, but I have to say that background music isn't going to suit some people's taste and its always a difficult choice.
Sometimes the rules of where I could get rid of tiles and where I couldn't were a little confused, so that is something you could always clean up, but it was generally very good.
Long lifespan, great graphics (detailed, very pretty) and nice and relaxing. A great game.
