Manipulate the swinging, hinged pieces of Ivan's Hinge. What starts out as simple pleasure in flexing vivid pieces & sections- leads to head-scratching challenge when you attempt to match one of the brilliant pattern cards. Knit together a solution in your mind... then play it out by folding, looping, turning, and bending. All wrong? Untwist, unweave, unwind - and have a go again! Finally, you'll alight on a solution. Then, Aha! -another. A couple of successes, and you'll aim to wrap your mind around a solution for every pattern card included! Match your creation to the pattern pictures once, and you'll resolve to re-solve Ivan's hinge again & again!
