From Hasbro Games. It's grid-spinning, game-changing fun in this strategic game of weights and balances! Players choose where to put their disc into the grid, and then spin the column to line them up. They need to get 4 in a row-horizontally, vertically, or diagonally-to win. But they also need to keep an eye out for their opponent's disc placement before spinning or they might throw them a victory. Each set of discs includes a weighted disc that can change the game in an instant.
