It was a work kit developed for our second annual "Karakuri Puzzle inHakone" in 2012.
It is a traditional five-move secret box.
We were going to make a four-move secret box at first, but we wanted more participants to understand the secret box.
Therefore we added the device called "the bolt" (bolt).
