Created by internationally recognized puzzle inventor Ivan Moscovich, a former prisoner in Auschwitz concentration camp, Ivan's Hinge is the hardest puzzle we sell. And yet, it remained one of our best sellers at 2012 homeschool conferences, purchased as often for brilliant spouses as it was for know-it-all teens. The design is ingenious, yet simple. Just choose a card, then fold, loop, bend, and twist Ivan's Hinge to match the pattern--that is, if you are able to. The cards can be solved, but they require some serious visual-spatial skills, while the articulating joints make Ivan's Hinge an irresistible combination of perplexing puzzle and soothing fidget toy. Ivan's Hinge includes not only the brightly-colored hinged manipulative, but also fifty-six colorful challenges printed on sturdy cards.
