This game is played in a similar fashion to Connect 4 where rounds may be won by scoring 4 tokens horizontally, vertically or diagonally. Additionally, a player may win a round by creating a diamond with his/her tokens -- that diamond must contain the opponent's token in its center. The game is played in multiple rounds. First player to win 9 rounds wins the series. Red and blue tokens come with pro baseball team stickers. From the back of the box: Horizontal? Vertical? Diagonal? Diamond? Let the Rivalry begin! Connect 4 Rivalry Edition adds fuel to the fire. Drop your team's checker into the field to make a line or diamond! Plan your moves, block your rival & show no mercy. Bring the rivalry home and settle the score with new rules & game play.
