These pages are the pages you'll use to submit your entry to the Codebreaker Competition. Please read each step carefully to make sure that your entry is accepted.

Before you can submit your entry, you need to make sure you have everything you need. Please check that you have each of the following things:

  1. You need to have uploaded the Greenfoot file for your entry to the Greenfoot Gallery, and you must have made a note of the address for your Greenfoot Gallery entry.
  2. You need your submission token. Ask your teacher for this - they were sent it when they first registered your school or class for the competition, and they can find a copy of it on their teacher profile page. If your teacher doesn't have a submission token, they'll need to register here to get one.
  3. You need your video file. Make sure you know the name of the file, and which folder on your computer it's stored in. The maximum accepted file size is 50MBytes, and the video must not be more than 60 seconds long.
  4. You will need an email address we can contact you at. This address must be unique to you or your group, if you do not have an email address, please contact your teacher for help.
