Abstract

Abstract A modified chess game which can be played by two, three or four players simultaneously. The game apparatus includes a chess board, four different colored sets of chess pieces and four strategy blinders. The chess board has 100 squares and is divided into four colored sections which match the colors of the chess sets. Each section includes 25 squares, 9 alternating black and white squares along its frontier borders and 16 alternating colored and white squares in its interior. At the corner of each section are four gold stars in four squares. Along the outer borders of the sections are colored numbers which match the color of the sections to which they adjoin. Each set of chess pieces includes 16 conventional chess pieces. They are positioned on the inner 16 squares of the corresponding colored sections by a player in accordance with the strategy agreed on beforehand. All of the chess pieces, except the pawns, are moved as in conventional chess. The pawns may be moved one square at a time, forward, backward or sideward. The pawns may be moved diagonally only to capture an opponent's piece. The object of the game is to checkmate the opponent's king.
