Two farms, one road. You hide three herds in your field. The neighbor hides his across the road. Pick a square over there and your tractor drives up and throws a feed bucket on it. A moo is a cow.

Every third round the loose herds graze one square along their line, into ground you have not tested. Your buckets are fences. Pen them in. Tag one cow and that herd stops where it stands.

Two runs for the cattle dog a match. He goes down a row or a column, tells you how many loose cows he smelled, not where, and leaves one bucket on bare ground on his way through.

How to play

• Setting your herds: drag a herd to move it, tap it to turn it. SHUFFLE deals them out for you. TURN THEM OUT starts the match.
• Your turn: click or tap a square across the road.
• The dog: press SEND THE DOG (it cycles row, column, off), then tap any square to run that line.
• P pauses. Sound and pause are top right.

Plays in the browser, on a phone or a desk. Free, nothing to install, no account. A match runs a few minutes and the next one is one tap away. Leave mid-match and it is waiting on the title when you come back.

Two neighbors on the title. Easygoing figures cows stand still. Sharp tracks them and uses his dog. Start on Easygoing.

How AI was used. The code was written with Claude. The neighbor is a particle filter over herd placements: a few hundred guesses that die when a bucket contradicts them and walk when the herds do. The cows, buckets, tractors and dog are AI-generated (three overhead sheets, Gemini), chroma-keyed, then printed down to the game's sixteen inks by a script of our own. The field, road, fences, paper menus and copy are hand-made. Audio is synthesized in code. Built on the HABB engine (mdawg74.itch.io/habbengine).
