Keep your collection across visits

Guest and account collections are separate

Guest play keeps progress on the current device. On the hosted website this uses browser storage, so clearing the site’s data can remove a guest collection. Signing in selects a separate collection associated with that account.

Sign in before starting a collection you want to use across devices. Guest progress and account progress remain separate.

Give private sync time to finish

Changes to your signed-in collection sync automatically after a short pause. Check the account page or the saved-status indicator before leaving. If a save needs attention, follow the on-screen instructions.

A new device restores the account’s saved collection after sign-in. Internet access is needed for authentication and cloud sync. Card artwork is separate from the private collection snapshot.

Resolve a conflict deliberately

If two devices change the same account before syncing, a revision check prevents an older snapshot from silently replacing newer cloud progress. The account page asks which collection to retain. Read that choice before restoring; unsynced local progress may differ from the cloud copy.
