CS50x Puzzle Day is an opportunity to collaborate on teams of 2, 3, and 4 to solve a packet of puzzles (i.e., logic problems). Among the event’s goals is to send a message that computer science is more about problem-solving than it is about, say, programming.

Puzzles are not programming challenges. No prior CS or programming experience needed, just logic and smarts! No team? No problem! We will help teams form at the event. Tickets on sale until 4pm on November 4, 2026.
