PRO-GRIDIRON is played by two opponents on a rectangular field (board) consisting of sixty-four rectangular, half light color and half dark color. Each opponent has a team consisting of sixteen pieces. All the pieces of this game have their own value and power relative to the HEAD COACH. With his authority and strategy, the HEAD COACH’S ultimate desire is to beat the opponent’s HEAD COACH. When a piece can force the HEAD COACH to move, this is called a Down. If he stops the HEAD COACH’S movement, this is a Touchdown. The first team to get a Touchdown, therefore, wins the game.
