Tidemark — The Bellweather Isles

A small island. Three rival houses. A coast to call your own.

Tidemark is a single-player settlement strategy game set among the Bellweather Isles. Found villages, connect them with roads, trade your surplus, and raise towns and coastal beacons. The first house to the chosen renown target wins.

Explore a miniature 3D island with carved shores, working landscapes, quiet waves and passing sailboats. Every new voyage draws a fresh chart; save a chart number to revisit the same island.

• Two computer rivals with different building and trading priorities.

• Choose your captain, house colour, landscape, starting supplies and voyage length.

• Automatic saves, a field guide, optional guidance, Normal/Fast presentation pace and reduced motion.

• Mouse and keyboard controls on desktop, with a separate touch layout for mobile.
