Horsey Game

Horsey Game is a tiny 37 MB indie sim where the entire economy is horses. You collect them, breed them, race them, genetically modify them via a tongue-in-cheek "horse science" system that basically lets you turn your stable into a min-maxing optimization puzzle. The whole thing presents like a cheerful browser tycoon game, then turns out to have surprising depth in the breeding mechanics if you actually engage with it.

Captain Games released it in February 2026 with regular content patches since then; this download is build 22948587 with all current horse breeds, race tracks, and genetic-modifier unlocks. The "create a paradise OR get rich" framing is meant literally — the late game forks between a peaceful horse-sanctuary path and an optimize-the-bloodline-for-the-track empire path.

Released with CSF + Goldberg, fully offline-playable. 37 MB total install. Single-player only.
