Common questions

Do I need an account?

To play against the bots, no — the chess engine runs on your phone and works with no connection at all. Online play against people, your rating, the leaderboard and syncing between devices need an account: a guest account, Google sign-in, or Sign in with Apple on iPhone and iPad.

Will other players see my real name?

No. Your handle is the only name anyone sees. Even if you sign in with Google or with Apple, we never read or show the name, photo or email address that provider holds — including an Apple private relay address.

I lost my progress after changing phones

A guest account lives on one device only. If you signed in with Google or with Apple, sign in again on the new phone and your rating, history and cosmetics come back. Open Settings → Account and link Google or Apple to protect a guest account before you switch.

How do I change my handle?

From your profile. A handle can be changed once every 30 days, must be 3–16 characters (letters, digits and underscore) and must not already be taken.

My game disconnected

Reopen the Game — an unfinished online game is picked up where it left off, and your clock keeps running while you are away, so reconnect quickly. If both players go away, the game is closed automatically and nothing is rated.

How do I play a friend?

Create a room, share the 6-character code with your friend using your phone’s share sheet, and they join with that code. The room expires if nobody joins. Games between friends are never rated.

Are coins real money?

No. Coins are earned by playing and only buy cosmetic items. They cannot be purchased and have no cash value — see our Terms of Service.

How do I report cheating?

Email contact@cognitivesquad.comwith the date, the time control and your opponent’s handle. Our server already verifies every rated result and flags suspicious play.

How do I delete my account?

In the Game: Settings → Delete account. Full details, including how to ask by email, are on the Account Deletion page.
