The game rule is to reorganize the above items in such a way that at least three of the kind are placed in a row (vertically or horizontally, not diagonally). If they are set like that, they are removed from the board and the number of points is scored as well as some time available in the game is added (see - OPTIONS).
Particular parts are moved by clicking the item to be moved and then clicking the item we want to swap. The target item MUST be on the field which adheres to the item that was clicked first (up, down, on the right or on the left). The fields which remain vacant as a result of the operation will be filled with items generated at random.
