In this game there are two game modes: normal and infinite. In normal mode there are 28 levels. To complete a level player must contruct a loop from a random pieces which connects all control points. When loop is constructed it disappears and this brings points to a player. For every 2.500 points player gets an extra 'credit'. Every time when player doesn't place a piece on a board he lost a credit. When there is no credits left the game is over. When playing infinite mode there are 4 extra piece types, no levels and controls points. The game is over when there is no credits left.
