Description

Find pairs of symbols. When you select pairs, they are removed. Challenge CODESYS and try to remove more tiles than CODESYS. CODESYS plays a very simple strategy, but is hard to beat.

At the beginning, the game is started with a field of 144 tiles with 36 different symbols. A tile is considered to be open when it can be moved either to the left or to the right without touching other tiles. The goal is to match open pairs of identical tiles and remove them from the board so that the tiles underneath are exposed. The game is finished when all pairs of tiles have been removed from the board or when there are no exposed pairs remaining.
