The point of this game consists in memorization of 500 mostly used Chinese characters. The player removes characters from the board by clicking on them. The player wins when all characters are removed. The payer loses when he tries to remove a character that differs from the one previously removed, of course in case it is possible to do otherwise.

Thus, if you removed 'A', then you are trying to remove 'B' though there are still characters 'A' present on the board, you will lose.

The game does not imply memorization of pinyin or character meaning. The idea is to force the player to memorize characters as they are, their graphical appearance.
