Are you looking for a puzzle that is tricky to solve at
first, but then can be used to store things after you solve it? Then the Treasure Chest
puzzle is for you. As the name would imply, quite a lot of useable space rests inside this
small puzzle. This space is in the form of a drawer, as to make storing things that much
easier.
As a puzzle, we rate it as Moderate. It's rather tricky the first
time, then easy.
A mechanical puzzle is a self-contained object, composed
of one or more parts, which involves a problem for one person to solve by manipulation
using logic, reasoning, insight, luck, and/or dexterity. - Jerry Slocum
