The box cover invites you to "Turn your Mind to the Challenge". A four-in-a-row variant where the board is made of concentric rings that can be rotated. Players place one peg at a time into empty spots and then use that peg to rotate the ring. The game comes with "standard" and "advanced" rules; the advanced rules allow players to capture pairs of opponent's pegs. In either set of rules, the first to get four of their pegs in a radial row wins.
