You're invited to CS50x Puzzle Day 2016

CS50 and Facebook present... CS50x PUZZLE DAY 2016 2 DAYS OF PUZZLES AND PRIZES Open to CS50x students around the world (and friends). Team of size 2, 3, or 4 encouraged but not required. Register at http://cs50.edx.org/register. Invite friends. Visit http://cs50.edx.org/teammates if looking for teammates. HOW IT WORKS * On Friday, 12 February 2016 (in your own time zone), your team will download a packet of puzzles (written by our friends at Facebook)! We'll email you a link by 00:00 that morning! * Your team will then have until the end of Saturday, 13 February 2016 (in your own time zone), to solve as many puzzles as you can. You'll submit your answers online. * Your team is welcome to work on the puzzles online or in person (by yourselves or alongside other teams). * After Saturday, 13 February 2016, we'll post a walkthrough video in which we explain the (correct!) answers. * Prizes will be awarded pseudorandomly to (a few) teams who answer the most questions correctly. * All teams will be featured on a Big Board that announces how many puzzles each team got right (unless you opt out). * Puzzles will not require prior programming experience, just logic and smarts. All you'll need is a computer with Internet access, a pen or pencil, and scratch paper. WANT TO HOST?
