Trama (1990)

A strategy game that can be played by two or three players. It consists of a triangular board and three sets of seven pieces in black, white and gray. The pieces are placed on the starting triangles opposite the corner (home triangle) with the same color. The object of the game is to place one of your pieces in the corresponding corner. The two-player game has an interesting twist in that the gray stones are neutral and can be moved by either player, but they can be used to capture opposing stones. A stone is eliminated if it is surrounded by two of your stones (in the three-player variant) or by two of your stones, two neutral stones, or by one of your stones and one neutral stone (in the two-player variant). In addition, no more than four checkers of the same color can be aligned next to each other.
