3D Printed Puzzle Challenge

A monthly puzzle challenge at the Harold Washington Library Center, this one pits high school teens aged 13 to 19 against each other using the library’s collection of 3D-printed puzzles. New challenges arrive each month, and the difficulty range is broad enough to include both casual solvers and seasoned competitors. It runs on Monday, September 21, from 4 to 5 PM. Free, but contact the library at least two weeks ahead if you need sign language interpretation or other accessibility support.
