Amongst my last hoard of puzzles (a term I have taken to using to describe the suitcases of my friends who went to the IPP) from Puzzle Master, I received a wire and string puzzle called Keyhole. I got this one because I had decided that it might be a good idea to try my hand at some of the more complex wire puzzles to give myself a bit of a challenge. This one is indeed at the top of their scale at 10 out of 10 (Mind Boggling). Plus with the apparent simplicity of it, I thought it would be a pleasant solve process. Made of wire, sturdy string and painted wooden baubles it measures 12 x 4.9 x 2.5 cm and is a nice tactile puzzle to hold and play with. No solution is included but one can be downloaded from here.
