Hanayama Brain Teaser Puzzle Level 6

Elk

'At the end of the 19th century, Britain experienced a huge puzzle craze. I managed to pick up a number of the puzzles famous from that period in flea markets, despite their rarity. Based on these original puzzles from Britain’s famous puzzle period, this is one that we have successfully revived in its new form. The key word here is 'antlers.' Can you free the antlers… and then put them back together again?'

-Nob Yoshigahara, 1986

Hanayama Brain Teaser Puzzle Level 6 - Chain

'There’s a whole of wisdom wrapped up in this Oskar Deventer masterpiece. The three pieces can be separated and then joined again in their original form. What’s special about this puzzle is that it can be solved three different ways, depending on which of the three pieces is chosen as the middle piece. Solving this puzzle requires an especially subtle kind of working of the pieces, the kind that often leaves the victim struggling in frustration. Keeping in mind its chainlike behavior and using your feeling to your advantage is the best way to attack this. The key word is 'chain.'

    Hard, but easy puzzle.
    This puzzle took me about 20 minutes to figure out but it was fun the whole time. At first it was really hard, but when I figured it out, it was super easy and was so surprised at how simple it really was. Don't overthink and you'll be able to solve it!
