How do I play?

Take turns placing dots on the grid. Link your dots into walls, and close a wall around your rival's dots to capture them. The player with the most points wins.

Report a game issue

  • Your device model, operating-system version and game version, if available.
  • The game mode, what you expected, and the steps that caused the problem.
  • A screenshot if useful. Remove notifications and other personal information first.

Where is my notebook saved?

Your coins, covers, pens and saved games are stored on your device. To keep a copy for a reinstall or a new phone, sign in to Google Play Games from Settings → Cloud save. We can't see or restore your saved games ourselves.

Why do I see ads?

Ads keep the game free. Rewarded videos are always your choice. There are no in-app purchases.
