SEARious Burr 13 piece burr with secret lock
Edward Hordern Puzzle Exchange - Chicago, USA, August 2003
Another completely new design by Brian Young.
The puzzle is to take the SEARious burr apart. Modelled on Chicago's tallest building, the Sears Tower, Brian created this 13 piece interlocking burr. But it's so much more than just an interlocking burr; incorporating the use of tools supplied as part of the puzzle it's biggest challenge is to open the secret lock. It will take 13 moves to unlock the secret internal mechanism. (The elegant solutions does not involve force, or banging, or hitting against another surface).
Considering it has no gravity pins or magnets Brian considers it to be the hardest progressive move discovery puzzle he's designed so far.
Is 13 your lucky number?
