This is an old game which was created in China many centuries ago. It is a wonderful game for training attention and concentration.
It is better to start from the easy game as it can help to understand the rules of the game perfectly well.
The aim of the game is to clear away all the tiles from the playing field and to take the figure to pieces to do it you should look for two similar tiles which are not connected with the others tiles either on the left or on the right. If the tile is not blocked with the other ones, you should clock it with the left button of the mouse and then extract it. After that they will disappear and you should look for the next ones.
In the difficult level of the game the figures are not flat. They consist of 2,3 or 4 rows.
There is a hint in the game.
If you press the Question Mark button, the computer lights up the suitable pair of tiles. But the hint is useful only if there are no suitable pairs of the tiles.
There is also an opportunity to mix the tiles if you don’t like the computer’s choice. Or you can start playing at any time you like.
