Sumo Dice is a 2-player tactical microgame that uses a couple of d6 to simulate a Sumo fight. Each player controls a die that represents a Sumo fighter. When the die moves, it changes its face-up side, and if you land your die adjacent to your opponent with a face-up number greater than his, you push it a certain number of spaces. To win the game you basically must throw the adversary out of the board. You also win if your opponent receives 3 damage, that is usually caused by terrain features like a pit.
