Save and return

Your island is saved on your device#

The initial game automatically saves reservation and policy changes and completed turn updates on your device. There are no accounts, cloud sync, device-transfer features, or online multiplayer. Resume using the saved island on the same device.

This official website provides information and the manual. Opening this page does not create an island or synchronize a game's save data with the site.

Returning and handling save errors#

When you return, wait for elapsed turns to finish processing, then read Journal and check held actions. A longer absence means more turns to process.

If an error appears, read the message, check matters such as available device storage, and use Retry. An update whose save failed is not treated as successfully saved. If the error repeats, keep a note of the message and what you were doing.

Actions that may remove your island#

• Uninstalling the app, clearing its OS-managed app data, or resetting the device can remove saved islands.
• In the development browser version, clearing site data or deleting the browser profile can remove the island.
• If multiple browser tabs produce a stale-state warning, reload the older tab and confirm the current state before making changes.
• Installing the app on another device does not automatically bring your earlier island with it.
