This incredible dodecahedral “Petaminx” twisty puzzle was all hand-cast, hand-assembled, and hand-colored (okay, “hand-stickered,” but still…).

    This should be titled “And you thought an 8 sided puzzle with 72 colored squares was hard to solve.”

    On a side note I have a feeling the person who designed this would be an expert at torture.

    Zof, I want to know where you buy puzzles, I recall a fun 6 sided puzzle… with 54 colored squares… but the almighty eight sided puzzle has eluded me all these years..

    Thank the heavens for you Disjunto! My life dream suddenly becomes a reality

    I suggest you leave the corners and center of each side black to make it harder to solve.

    This has so many practical uses, like a butt-plug, a medium-light throwing missile, a paperweight, a dog’s toy, a fake eye for giant squid and even as an effective stroke inducing ‘stubborn nerd’ killer. Alas, it will most likely remain forever a humble impossibly difficult puzzle for one man and a talking point for the millions who stumbled upon this like myself. how boring.
