Kyodai Mahjongg Rivers 1.1 for Windows Mobile Pocket PC

The layout is replaced by a large wall full of tiles. This time, you can select any tile you want. The goal is the same : remove all the tiles from the board, by matching them by pairs. There is only one rule to connect two identical tiles : if you try to draw an horizontal and vertical line through the free space between them, there must not be more than two corners in the line, i.e. if you have to turn more than twice to arrive in front of the other tile, you can't select it. Of course, if two tiles are side to side, you can remove them immediately. If you don't understand the rules, try the game for some minutes (and press "Hint" a few times), I'm sure you'll finally understand ! This game variation is absolutely great. There are two difficulty levels : Easy mode features only one floor of tiles, and Hard mode features two floors. It is even more than twice harder because you may mistake the floors between themselves, and still, you must finish the floors independently.
