In the November 1978 Word Ways, Mary J. Hazard introduced a word game by Dave Silverman in which two players alternately assign letters to the vertices of a cube with the objective of forming four-letter words on the vertices of each face. Specifically, a player loses the game if he is unable to form words on all faces on which his letter fills in the last open vertex. If this never occurs, then the player who fills in the last open vertex on the cube wins the game.
