Math Jams
Math Jams are free online discussions hosted by Art of Problem Solving for a variety of purposes, including:
- Informational sessions about Art of Problem Solving classes.
- Review of the AMC and AIME competitions.
- Introductions to new topics in math and other areas of study.
- Special events, such as our annual discussions with admissions officers and professors from outstanding universities such as MIT, Carnegie Mellon, Stanford, and Duke.
To attend a Math Jam, simply sign in to Art of Problem Solving just before the Math Jam begins, and click on the Classroom bar that will appear on the screen. The Math Jam classroom will open 10 minutes before the Math Jam begins. (See Classroom System Requirements)
Our Math Jams are held in the same online classroom as our online courses. Click here to read more about how our online classroom works.
Participants in Math Jams must be signed in as Art of Problem Solving Community members to access the Math Jams. Click here to or set up a new account. The Math Jams and Community membership are free.

A Sudoku For Mathematicians
Instructor: Dave PatrickDifficulty Level: 5* (Intermediate math)
7:30 pm ET
This sudoku puzzle was distributed at the 2025 Joint Mathematics Meetings earlier this year. It was designed to challenge some of the best mathematicians in the world. It's no ordinary sudoku: it has lots of special rules, some of which involve number theory!
Try it for yourself, and then come to this Math Jam, where we'll work through the full solution and explain all the problem-solving tactics used along the way.
