Quick fixes

Progress and offline play

Campaign progress, settings, personal-best times, and local replay data are saved on this device. Offline campaign play does not need an account. Private browsing, clearing site or app data, uninstalling, or changing devices can remove local progress. Online account creation does not back up settings, Hard Mode, or unverified local records. Accepted current-version bests can restore their corresponding completed levels and unlocks on another signed-in device.

Account sign-in

Leaderboards

You can browse published scores without an account. Signing in enables score sync: eligible current-version local bests already on this device and future clears upload their deterministic replay proofs for server verification. A result can be rejected if it is incomplete, altered, too large, from an older level or ruleset, or cannot be re-simulated. Your local result remains available even when an online submission fails.

When reporting a leaderboard problem, include the level number, displayed ruleset or game version, approximate time, public username, device/browser version, and the exact error message. Do not attach a password, authentication token, or sensitive device information.

Privacy and deletion

Read the privacy notice or use the account deletion page. Clearing local data and deleting an online account are separate actions.
