Contact
Bug reports, requests and anything else are welcome by email. Every message is read, but we are not able to reply individually. Reports are answered by acting on them rather than by writing back.
For a bug report, telling us which iPhone and iOS version you are on and what you were doing when it happened makes the cause far easier to find.
Reporting an inappropriate display name
You can report a name from inside the app. Open Leaderboard from the lobby and tap the flag icon at the right edge of the row. After a confirmation, the display name is sent to us. Nothing is shown to the reported player.
Email works too. Write to the address above with the name and where you saw it (which leaderboard period, for example).
Either way, we review every report and will change the name or suspend the account.
Display names are stored separately from accounts, so a name can be replaced without erasing anyone’s match record.
Frequently asked
Do I need to create an account?
No. One is created for you the first time you launch the app. There is no password and no email address to set.
Can I play without signing in to Game Center?
Yes. Without a Game Center sign-in you play as a guest. Note that guest results are not recorded — they do not appear on the leaderboard, in your history, or in a season. To keep a record, sign in to Game Center from the iPhone Settings app.
I lost signal during a match.
The board lives entirely on the server, so reconnecting puts you back in the same position. If your rival never returns, or the clock runs out, the match is settled automatically from where it stood.
No one is matching with me.
After thirty seconds you will be offered a CPU match. Matchmaking keeps running while you play it and pulls you across the moment a person is found. CPU results do not count toward the leaderboard.
How do I change my display name?
From the account screen. Names already taken by someone else are not available, and names cannot be changed repeatedly in quick succession.
How do I delete my data?
The account screen has a delete option. It removes your match record and display name. Deletion cannot be undone.
