Blue Circles app for iPhone and iPad
Blue Circles is a game where you get points by making lines of twelve.
The game starts off with three pieces each with the numbers one to five, plus one extra three. These pieces are randomly divided between the top player (you) and the bottom player (the program).
Players take turns dragging one of their unused pieces to an empty circle on the board. Each time a player makes a vertical or horizontal line of exactly twelve, the player scores a point. The player with the most points wins.
