144 MahJongg tiles, 4 each of 36 different tiles (all of the seasons are considered the same tiles, all of the flowers are considered the same tile). Object To remove all the tiles in pairs. Layout and Play
• | 144 tiles in a 16x9 rectangle - remove matched pairs of identical tiles that can be connected by a line with no more than two right angle turns. The line may not pass over any other tiles (it must pass through empty space). You can also remove any two matching adjacent tiles.
• | In the above example, the pair of 4 bamboos can be removed as they can be connected by a line with only two right angle turns. There are also two pairs of 3 circles that can be removed. Note that the pair of 2 characters cannot be removed as a line would need to turn 3 times to connect them. Only after some other tiles have been removed (as in the image below) can they be paired.
• | To select a pair of tiles, click on the first tile, then click on the second tile to remove the pair. Right click on a tile to show any possible match for that tile. Right click in an empty area to show a possible match on the board.
• | Keyboard shortcuts - Control-H (Hint) will show a possible match. Enter (Accept) will remove the match.
• | When there are no move available groups to remove, you will have the option to Undo, Restart, or Shuffle.
Notes
• | This game differs from Four Rivers in that you can remove pairs of adjacent tiles even if they are not on an edge. This makes the game somewhat easier than Four Rivers.
• | There are always two pairs of each type of tile.
