The game is simple— create lines of adjacent circles, the number of which is determined by the selected variant. You may only draw one line for each circle you play, so choose wisely. In the T (touching) variants, lines can intersect and join at the ends, but cannot overlap; in D (disjointed) variants, lines may not join at the ends. The object of the game is to achieve the highest score possible before running out of moves.
