TriTrap is played on a triangular board with the extreme triangles removed. Players have three pieces that move one, two, or three empty triangles per turn. Motion is across the sides of triangles (not the vertices) and a piece cannot end a move adjacent to a friendly piece. You win by surrounding an opponent piece on all sides with your own pieces.
 
An opponent piece in an edge triangle can be trapped by surrounding it on the two adjacent triangles. Stalemate is a loss for the player who cannot move. Repetition is also treated as a loss in this implementation.
