LEGO® Reverse-Engineering Challenge: Days 6-17

Posted by Admin
We are a little behind with sharing Ryan Howerter's REC puzzles with you (been too busy organising our own building contest!) so here is a bumper crop to give you a challenging LEGO® challenge to fill your days. Want more? They appear on Ryan's Instagram at 11am Mountain Time every day (and we also try to publish them on New Elementary's Twitter at the same time).

Welcome back to the Reverse-Engineering Challenge, or REC for short. Simply look at these small LEGO builds, and try to figure out how they are built. Always assume the hidden side is identical. The colours are irrelevant. No rubber bands and no flex tubing allowed! It's not a contest, there are no prizes – think of it more like a daily crossword puzzle. Solve as many as you like, at your own pace. Solutions are posted every Sunday at https://linktr.ee/rhowerter.
