4 Sun 53 Step Puzzle Box (Self Assembly Kit)

This puzzle box works very similar to the traditional Japanese puzzle box, in that all the moves are controlled by only two sliders, one at each end.These sliders allow the end panels to move vertically, and they in turn allow the top and bottom panels to move horizontally. Eventually, the top panel will slide off sideways. That's what normally happens...However, just when you think the lid is about to come off, the box appears to lock up. Strangely, the only way to get the lid off, is to start closing the box again...This sounds just like "The Bridge" puzzle box, but just when you think the lid is ready to come off, the box locks again! Because you've taken the wrong path.This box is similar to "The Bridge", but there's extras moves and an extra path put in, and now takes 53 moves to open. This puzzle kit has alignment pegs built into the parts to make assembly easier and virtually every part in the kit is labeled. The inner box is comprised of 1/8" plywood with a 1/8" Walnut outer
