- The site reports three reward hacks and fixes; its five-model ARC-AGI-2 rank correlation is presented as a direction, not proof.
Field notes
Players assemble bodies from parts such as flagella, chemical sensors, shells, and toxins, then wire a small neural brain before releasing organisms into the simulation. The site says matches use generated worlds and opponents that change their play, and describes three scoring exploits that led to rule changes. Its five-model comparison with ARC-AGI-2 is explicitly framed as suggestive rather than conclusive.
