Puzzle Day was a challenging but rewarding experience in the CS50x course. The puzzles were designed to be solved within a short time frame, which added to the excitement and pressure.
The puzzles were carefully crafted to test our problem-solving skills, and we were given a set of hints to help us along the way. We were also encouraged to collaborate with our peers to find creative solutions.
One of the most important lessons I learned from Puzzle Day was the value of persistence. I remember one puzzle in particular that took me hours to solve, but with each attempt, I gained a deeper understanding of the problem.
Collaboration was also key to success on Puzzle Day. Working with others allowed us to share ideas and insights, and we were able to come up with innovative solutions that we might not have thought of on our own.

Organizing and Hosting
Hosting a CS50x Puzzle Day can be a fun and rewarding experience. In-person events can be condensed into a single day, which is a great way to keep things engaging and focused.
A sample timeline for a Puzzle Day on campus shows that a single day can be enough to keep participants engaged. You can use this as a rough guide to plan your own event.
To make the most of your Puzzle Day, consider hosting it over a few days, just like CS50x Puzzle Day. This allows participants to take their time and enjoy the puzzles at their own pace.
How It Works
To host a puzzle-solving event, you'll need to understand how it works. Your team will download a packet of puzzles as a PDF from cs50.ly/puzzles, anytime after midnight on Friday, April 1, 2022, in your own time zone.
You'll have until the end of Monday, April 4, 2022, to solve as many puzzles as you can. This gives you a good amount of time to work on the puzzles, but not so much that you lose momentum.
To submit your answers, you'll need to fill out a Google Form at cs50.ly/submit. Take photos or screenshots of your team working on the puzzles, as these will be shared online if you'd like.
On Tuesday, April 5, 2022, at 1:00 PM EDT, you'll have the option to attend a live Zoom-based walkthrough of the puzzles' answers. If you can't make it live, you can also watch on demand afterward.
To keep track of progress and see how your team stacks up, CS50 certificates will be awarded to the teams that answer the most questions correctly.
Here's a quick rundown of the timeline:
- Friday, April 1, 2022 (midnight): Puzzles become available
- Monday, April 4, 2022 (end of day): Submission deadline
- Tuesday, April 5, 2022 (1:00 PM EDT): Live walkthrough of answers
Setting the Tone
Encourage a mindset where problem-solving and creative thinking are the main goals, not just winning. This will help participants have fun and enjoy the process.
Having fun should be the most important thing, and prizes should be kept in perspective. If you do decide to give out prizes, consider setting up raffle prizes to make it more inclusive.
Be mindful of how you communicate the prize aspect to avoid discouraging people from attending.
Hosting Your Own
Hosting Your Own can be a fun and rewarding experience. You can host a Puzzle Day like CS50x, which can be held over a few days, but in-person, a single day is sufficient.
A sample timeline for hosting a Puzzle Day on campus is available, but you can adapt it to fit your specific needs.
