Many Word Ways readers are familiar with the game of Ghost. In the two-man version of this game, players build sequentially toward a word by alternately adding terminal letters; the one who completes a word loses the game. After a player has added a letter to the sequence, his opponent can challenge him to produce a word starting with that sequence; if he can do so, the challenger loses the game, but if he cannot, the player challenged loses the game. Both players must agree beforehand on a dictionary of admissible words; ordinarily, words must be three or more letters long in order to be counted.
