Gamemaster General Game Playing multipleknightthrough Description Multiplknightthrough is a game played on three 3x8 boards. White pieces on the bottom two rows of each board and black pieces on the top two rows of each board. Pieces move like chess knights, except that can only move forward. White wins if it advances a knight to the 8th row of the second board, and black wins if it advances a knight to the 1st row of the second board.
