Definition: con·gru·ence: agreement or harmony; compatibility.
Congruence is best described as "Tron light bikes meets the ancient Chinese game of Go". It is a turn-based battle for territorial dominance. Send your puck flying through the randomly generated game board and pick a completed polygon to score.
Collect and use power-ups to lock, unlock, grow, and explode your captured region. You must balance your effort to collect powerups and score the most advantageous region.
