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 45 minutes on pen and paper exercises.

Each one covers math and logic, language, science, or reasoning. Some have a fixed answer. Others are more open-ended.

There is no grade. The point is to use your mind, deliberately, for a few minutes each week.

Solutions are in the session PDF bundles at mindclub.ca/shop.
