About Settlecoast
Settle the coast in a richly rendered 3D strategy board game. Gather wood, brick, wool, grain, and ore; trade what you have; and build roads, settlements, and cities as four settlers race to 10 victory points on Sunmere Island.
Play solo against three AI settlers, share a screen, or invite friends online. The live Settlecoast site requires a free confirmed Settlecoast account before any mode can be played; expansion islands and ranked play require Settlecoast Plus.
Creator Meng To says he built Settlecoast in four days entirely with GPT-6 Astra. His launch post does not identify the harness or a more specific Astra version.

A free confirmed Settlecoast account is required on the external site before play. Choose Play with AI, Play with friends, or Game lobby. Use pointer or touch controls for the board; on desktop, drag to orbit, scroll to zoom, and use WASD or Space plus drag to pan.
