Each player has 6 pieces lined up on his side of a 5x5 grid, either the rectangular or the rounded pieces. Pieces are transparent, and inside them are magnetized metal disks, one side red, the other white. In this distant variation on Tic-Tac-Toe, your ultimate goal is to arrange that 4 disks of your color are in a row, regardless of the shapes of the pieces. Under the board are magnetic strips of unknown polarity. As you place a piece into a new space, it might stay as it is, but it could also happen that the disk flipped and the piece joined your opponent's side. Options during a turn are either to enter a piece, move a piece, or jump a piece.Later published as Magic 4 by Discovery Toys and in Germany under the original title by Parker, where it was nominated for Spiel des Jahres of 1979. - BoardGameGeek
