Icosoku is a mathematical masterpiece! Position the tiles so that all of the dots encircling a yellow peg add up to that number. The puzzle can be solved every time, regardless of how the yellow pegs are arranged, so repeat play is endless. Crunching numbers has never been so much fun! Materials: Plastic. Dimensions: 7.5L x 5 W x 7.5 H; Weight: 0.5 lbs.
Yesterday I bought 3 pieces of Icosoku from Brookstone at price 28.99. It is useful and top product in this category of board games.
