42454Are keychain puzzles allowed?
- Aug 1, 2009Just pondering, would a keychain Pyraminx, or for that matter, any
keychain puzzle, be allowed for use in a competition? Would the chain
attached to a corner of the puzzle count as a "modification that
enhances the basic concept of the puzzle?"
Not that a keychain puzzle is practical or recommended, just wondering
what the rule on this is.
