tric-tac-toe v0.6.1, written by Sean McKean (Gamechild Software)

Description:
    The board resembles a Rubik's Cube surface; three players each
    take turns filling up the surface of the board. When no more points
    can be scored, a winner is declared according to the point totals of
    each player.

    The "tric"ky part is the connections on the board that score points.
