Round 2 of the 2020 Facebook Hacker Cup is less than 48 hours away!

The round will begin on August 29th, 2020 at 10am PDT and will last for 3 hours. The contest can be found here.

You're eligible to compete in Round 2 if you scored at least 25 points in Round 1.

Everyone who solves at least one problem will receive a Facebook Hacker Cup t-shirt, and shirts for the top 200 contestants will include a “Top 200” badge! We'll begin shipping out t-shirts by early 2021 or earlier, at which point the winners will receive emails with tracking information.

The top 200 contestants will also advance to Round 3, taking place on Sept. 12th. Please note that all submission judgments will only be revealed after the round end, and that time penalty will be used to break score ties. More details about rules and other information can be found in the FAQ.

We wish you the best of luck, and hope that you enjoy the contest!
