Two cards can be removed only if they can be connected with a maximum of three lines. Lines can be only horizontal or vertical. Lines may cross only the empty positions, positions with the overturned cards and can to go beyond a field. 3. Two cards of identical rank, but not necessarily identical suit, can be temporarily excluded from the game (overturned) if they can be connected with a maximum of three lines. At the second level of complexity the overturned cards have to be one color.4. If there no cards to remove, all cards turned before opens and starts the next round of the game.
