3D Printed Puzzle Challenge

A monthly puzzle challenge at the Harold Washington Library Center that swaps out its 3D-printed brainteasers each session, so returning competitors get fresh problems. This iteration runs from 4:00 to 5:00 PM on Monday, August 24, and is open specifically to high school teens ages 13 to 19. The library provides puzzles at multiple difficulty levels; bring a friend or find one there.
