Adversarial Nibbler is in its pilot phase and can accept submissions from now through the end of May 2023, however the interface may be intermittently down as we make necessary updates.

The full run of the challenge will launch June 1st and run through August 31st. Participation in the pilot round does not affect your eligibility for later rounds. Any future rounds will maintain separate leaderboards.
