If unfamiliar, 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). (Your team members don't need to have taken CS50x itself.)

See www.eventbrite.com/e/cs50x-puzz... for all details, including tickets. (Please forgive that space is limited!) Tickets available until 4pm on October 8, 2025. If ticket price would prevent you from attending, email [email protected].

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). 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.

Taught over 12 weeks, this course teaches you how to solve problems, both with and without code, with an emphasis on correctness, design, and style. Topics include computational thinking, abstraction, algorithms, data structures, and computer science more generally.
