If you already have a personal account, go login!

Otherwise, sign up for a personal account, and either create a new team or join an existing one.

Here's how you would register your team of 1 to 5 competitors:

  1. One member of your team creates a new team, choosing a Team Name and Passphrase.
  2. The team creator shares the Team Name and Passphrase with other members of the team.
  3. All other team members register and choose “Join an Existing Team,” providing the Team Name and Passphrase.

You can add new members to your team at any time, even after the competition starts.

If you receive an error on registration, please see below.

If you are having trouble registering, it is possible that your ad blocker or tracking blocker is hiding the Google "I am not a robot" checkbox from you.
This will result in an error message stating that "this field is required" even when all fields are filled out.

To fix this issue, please temporarily disable your content blocker or try registering using a different browser. Once registered, you can safely re-enable your blocker and/or use your old browser. If the error continues, please let us know here.
