The object of the puzzle is to remove all the tiles from the board. Tiles are removed by finding matching pairs and touching each one.
Tiles are matched if their face is the same and they can be connected by three or less lines.
Lines can only be horizontal or vertical and cannot pass over another tile not in the matching pair.
Lines may extend beyond the grid.
Touching "Any Matches?" button will tell you if there are still matches (moves) without revealing any more information.
Touching the "Hint" button will tell you how many pairs are currently able to be matched and will highlight one tile of a matching pair. Note: Choosing tiles suggested by the hint will not necessarily lead to a successful solution as prior moves may have made this impossible.
Touching the "Solve" button will solve the rest of the puzzle (if the program can). Failure to solve does not necessarily mean the puzzle cannot be solved from that point but the computer is not able to do so quickly. However, all puzzles are solvable - you may need to undo steps and try alternate sequences of moves.
There are three different sets of tiles to choose from, two classic Mahjong ones and one Wingdings. They are selectable from the splash screen by tapping on the tile image.
There are also three different number of tiles to choose from - 144, 216 and 288. Please note that for the phone version, the
only option for number of tiles is 76. This is due to space limitations on phones.
