And you can play with up to 4 human or computer players.
Each player is given a certain amount of triangles which make up his or her hand. Each point on a triangle has a number on it. Match the numbers on one of your triangles with numbers on the triangles already on the board to score points.
A well-chosen play may earn you additional bonus points for a "special play," but you may need to rotate a triangle to one of six orientations in order to play it. The first player to play all of their triangles wins the round, and the player with the most points after all rounds have been played is the winner.
