Rebuild The Civilization

A free colony simulator on a living hex world

Grow food, house families, face hard choices, and send expeditions beyond the mountains — in the browser.

Colony Simulator

Lead a settlement where every decision freezes time

The map is a hex-shaped valley — marsh, snow, forest, and a rock cordillera. Colonists age, work, fall ill, and can die. Far beyond the ridge waits an abandoned city; an expedition opens its district while your camp keeps running.

Sign in to keep up to three colonies in the cloud. Guest play is temporary — perfect for a first night in the valley.

The simulator is practice. The Knowledge Base is the manual for the real world — from soil and water to medicine and governance.
