This portable strategy game is similar to chess or checkers, but with a twist — the magnetic stones with unmarked north and south poles can jump out of their position at any point during the game, giving players a whole new element of challenge. "Jishaku" is the Japanese term for "magnet." The game received a 2008 National Parenting Center Seal of Approval, an iParenting Media Award, a Major Fun Award and a Mr. Dad Seal of Approval. Launch date: June 3, 2008.
— Tutoring Toy in Salt Lake City sells about 20 per month of this game, Buyer Casey Sartain told TDmonthly in fall 2009.
