Weekly Problems
Every Friday, you'll get one problem in your inbox, attached as a PDF.
The problems come from Mind Club sessions in Kitchener-Waterloo, Canada, where a small group puts their phones away and spends an hour on pen and paper exercises.
Solutions are in the session PDF bundles at mindclub.ca/shop.
On hiatus. Mind Club Weekly is paused while sessions are on a break, so signups are closed for now. To hear when it starts back up, subscribe to the Mind Club calendar.
