Hexa is part puzzle, part geometric torture device. The goal is to remove the hexagonal nugget of brass from the hexagonal bars of the steel cage. Of course, the chunky brass Hex doesn't seem to fit through any of the six-sided holes. This sort of puzzle can be particularly maddening since it's clear from the beginning what needs to be done yet it seems that every element of the object has been specifically crafted to work against you. Trust the clever designers at Randemic Puzzles to reward your patience and hard work with a lovely solution that could only be possible with high-precision manufacturing. The sculptural quality and contrasting metal elements make Hexa a handsome display puzzle. Measures approximately 2" x 3". Difficulty level 9 out of 10. Made in Czech Republic.
