Nutcase Cast Puzzle (Level 6)

The «nuts and bolts» appearance may lull you into believing this to be a straightforward cast metal brainteaser puzzle, but it is a total brain drain. Inventor Oskar van Deventer presents two challenges: 1) remove the small nuts by disassembling the nutcase, and 2) change the order of the wording on the bolts from «nut-case» to «case-nut.»
