Four clans churn the Ocean of Milk in a race to 10 Glory.
Asymmetric strategy set in the Hindu myth of the Churning of the Ocean. Move your beings across a hex board through Day and Night phases, harvest divine resources, and chase Glory through Tribute, Valour, or the climactic Great Churning. Playable in the browser — online multiplayer with room codes, local hotseat, or vs AI. Built on a deterministic TypeScript engine with an authoritative WebSocket server and an AlphaZero-style bot training stack. A print-ready physical edition is headed for SPIEL Essen 2026.

Asymmetric lineages, shifting environment cards across three eras, and a promoter-key chain that rewards planning. Balanced over ~100,000 simulated games with reinforcement-learning agents; a complete print-and-play kit and digital playtest table exist today.
