Stuck in
a corner?

Where can I get Cornered?

Cornered is in development for iPhone with iOS 27 or later. There is no public App Store listing linked here yet. If you’re testing a build, use the installation instructions from the person who invited you.

My placement won’t fit

Check the whole shape, not just the square you’re aiming at. Your first piece covers your start. Later pieces need a same-color corner, no same-color edges, no overlap, and every square on the board. See the full rules.

A friend’s move hasn’t appeared

Open the game again to refresh. While viewing a lobby or game in the foreground, the app refreshes periodically. Saved asynchronous games don’t require everyone to stay online. There are no configured push notifications or background live updates.

I have an invitation

Open the link on the iPhone where Cornered is installed, then choose “Open Cornered.” If that doesn’t open the app, copy the invitation code and enter it in the app. A full or already-started game can’t accept a new player; existing players can return to their game.

I changed devices or lost my guest identity

A guest token is device-bound. Without an Apple-linked identity, we can’t promise recovery after device loss or reinstallation. Don’t delete the app to fix a connection problem. If an Apple identity already belongs to another account, sign out and sign in with Apple to open that account; it does not merge the guest games.

Contact and feedback

A public support inbox has not been announced yet. If you’re part of a private test, report problems through the same channel that supplied your build. Don’t include your access token or private invitation links in public bug reports.
