Make a LEGO Mechanical Puzzle

Here’s a simple LEGO® challenge that is fun to build and play – build a three piece mechanical puzzle and figure out how to put it together!

We saw this idea on Instructables and decided to try it out. It works really well!

Build the three shapes below. Two of them are identical. Note that each section has three layers: a layer of regular bricks in the middle, a layer of smooth flat bricks on top, and a layer or regular flat bricks on the bottom.

Then, try to fit the three pieces together. It might take a few minutes to figure it out.

The finished puzzle should look like this:

If you can’t figure it out, head over to Instructables – there is a video that shows how it’s done!
