The only moving panel on this box is the lid, which
is held shut by eight sliders, all neatly arranged in one row. These sliders can
be slid to one side or the other, but there are no halfway points: they're
either "on" or "off", as it were.
If all the sliders were locking the lid, it would be easy to open, just move them
all, and the lid would be released.
If just ONE slider was holding the lid, that would be easy, too, just try each
one in turn, until the lid slides off.
But there's only SOME of the sliders locking the lid, and you can't tell which
ones, or how many. To make it worse, there's a number showing on each side of
the box, and this number is actually the solution to opening the lid!
Size is 5" by 3" by 2-1/2", and is made from 1/8” wood and plywood.
puzzle kit has alignment pegs built into the parts to make assembly
easier and virtually every part in the kit is labeled.
