This very professionally designed version of Mahjong has twenty-one levels. It doesn't use the normal Chinese characters, but has cartoons of cats on the tiles! The first level includes a brief tutorial, just to explain what to do. Each level is always the same, so the more you play, the more you get to learn the tricks of each level. If you don't believe that some levels CAN be solved, there is a built-in walkthrough available, just to show how it should be done! In practice, it is a much better game than you would expect from the rather bizarre name. Even for those who don't like cats, this is definitely recommended!
