In order to make sure ARC-AGI-3 games were solvable by humans we tested over 450 people If a game was too hard we either revised it or tossed it completely For maximum transparency we just open sourced all the human replays for public games My favorite charts that come out of these are the Action Progression charts. It's much easier to get a feel for how efficient environment solves turn into scores
