How do I participate?

If you haven't already, sign up to participate in the Hour of Code this year.

After (or during) your Hour of Code, post and tag one of our celebrities on Twitter, Facebook, or Instagram, including their @profile and the hashtag #HourOfCode.

This challenge is open to classrooms, after-school clubs, and individual students, starting today until the end of the day Friday, December 15th.

You can submit and post as many times as you like - but tag only one celebrity per post.

How do I increase my chances of winning?

The celebrities will work with to pick a winner. Read about what each celebrity is looking for, then, increase your chances to win with photos or videos of yourself or your class. They'd also love to see the apps, games, or artwork your students created, so add a link to your students' work!

The posts that have the most cool stuff will have a great chance of being selected, so include a link to the coolest code creations you made on, an ANIGIF of the app you made, or a fun video explaining your Hour of Code activity. Get creative!

Posts with more likes, shares, and retweets will also have a higher likelihood of winning. Add an Hour of Code frame to your Facebook profile picture to really get into the spirit.

And since you can post as many entries as you want, across Facebook, Twitter, and Instagram, feel free to make multiple posts to increase your chances. The idea isn't to spam the internet and annoy your friends, it's to celebrate computer science. So please try to make the content you post worthwhile for all of us.

How do you get the project link to share?

When you're done with one of our Hour of Code activities, click "Finish" on the last level you'll receive a share link. You can also take a video of you or your students demo-ing their app and share that.

How will the chat work if we win?

We'll work with you to set up a time when the celebrity can call into your class for 10-15 minute video chat. Your students will be able to ask questions live.
