The last weeks of ARC Prize.

Teams on Kaggle are building agents for ARC-AGI-3, little games with no instructions, and solvers for ARC-AGI-2's grid puzzles. Both boards close on the same night.

We save the public leaderboard every half hour and keep score: see the ARC-AGI-3 leaderboard, the ARC-AGI-2 leaderboard, all ARC leaderboards and the ARC Daily Digest, with its wire of short stories on both boards.

Also here: how we got here, our harness notes and practice games, plus official game guides (spoilers) and the resource hub.
