HZ 6-01 Cast Chain

Puzzle Ring – Purple

HZ 6-04 Cast Nutcase

There are two goals to the Cast Nutcase created by the Dutch puzzle inventor, Oskar: 1. Remove the small nut by disassembling the Cast Nutcase. 2. Cast puzzle enthusiasts (nutcase) can enjoy trying to change the wording on the bolt from ‘nut-case’ to case-nut’.

The key word is “interlocking”.
