When three links form a triangle, the player keeps his turn and makes another move. Each player has his own color. If a player's move results in forming a triangle, it gets painted with that player's color. If more than one triangle can be formed in one move, they all get painted. Your objective is to paint as much of the field's area as possible with your color.
Game is over when the entire field is painted.
The higher skill level you select, the more sophisticated strategy computer uses against you. Field dimensions are always displayed on the toolbar. You can set colors for both your opponent and yourself. There are 12 colors to choose from. The more of the game field is covered with triangles of your color, the higher your score is.
