If the orginal Hexa puzzle isn't difficult enough for you, this deluxe version includes an added layer of trouble. At the center of the conundrum is a brass Hex nugget. Wrapped around that is a hexagonal steel cage (through which the Hex must escape). On top of all that is a second steel cage that functions as a totally different kind of puzzle. The outer Hexxa cage arrives assembled. It is comprised of fourteen unique pieces which combine to create a cylinder. Be forewarned, disassembling the Hexxa cage is at least six thousand times easier than putting it back together again. So once you manage to remove the Hex from the inner cage and put it back, you'll still have a formidable task ahead of you. Measures approximately 2.75" x 3.25". Difficulty level 9 out of 10. Made in Czech Republic.
