Saved games

Each board size saves its own game and best score. Undo takes back one move. New game replaces the selected board while keeping your best score. We cannot recover local progress remotely. Avoid clearing app storage or uninstalling while troubleshooting if you want to keep your saves.

Appearance and motion

Tap the current theme name on the home screen or open Settings during a game to select Forest, Ocean, Sunset or Midnight. Settings also controls haptic feedback. Animations follow your device's reduced-motion preference.

Audience and advertising

Eleventh Power is intended for ages 13 and older. The current app does not ask for or verify your age. It uses restrictive under-age-of-consent advertising treatment for everyone and requests non-personalized, general-audience ads. Gameplay works without a network connection. Advertising and privacy forms may require one. When applicable, use Settings > Ad privacy choices to review your choices. Missing ads or declining advertising consent does not remove game features.
