One of the hardest and best-selling puzzles in the True Genius collection. The rules take five seconds; the solve can take weeks. Stacked rotating dials create thousands of possible alignments, and only the right combination makes every column total 42 — a challenge worthy of the Grecian astronomers who inspired it. The flat, medallion-like design looks like an artifact on a desk. Approx. 5.9\" x 5.9\" x 1.1\" Part of the True Genius collection of history-inspired brainteasers.\u003c\/p\u003e","brand":"Project Genius","offers":[{"title":"Default Title","offer_id":50293118271745,"sku":"TG406","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/2669\/0817\/files\/cc389debfcd1551050d9102f51466e0e224f30b8fcf705ec3812dab50bfec52e.jpg?v=1788819514","url":"https:\/\/joeleighcompany.com\/products\/true-genius-grecian-computer-wooden-math-puzzle","provider":"JoeLeigh Company","version":"1.0","type":"link"}
