Where do I get help with a specific game?
Each game has its own help pages: Bill's Sudoku support and Kingside Chess (open More inside the game). You can also email us any time.
Are the games free?
Both games are free for 30 days. After that, a single one-time purchase unlocks the full game for good: no subscription and no ads. Payments are handled by the App Store or Google Play.
Which devices are supported?
Bill's Sudoku is on the App Store for iPhone, iPad and Mac, with Android coming soon. Kingside Chess plays in any modern browser and can be installed from it on iPhone, iPad, Mac and Android; store versions are on the way.
How do I restore a purchase or get a refund?
Use Restore purchase inside the game while signed in to the same Apple Account or Google account. Refunds are handled by Apple at reportaproblem.apple.com, or by Google through Google Play.
My progress disappeared. What happened?
Games save progress on your device. Clearing your browser data, using a private window or deleting the app can reset it. For Kingside online play, your account key brings your profile back on any device.
How do I delete my Kingside online account?
In the iPhone, iPad and Mac app, go to Settings → Online account → Delete account. On Android or the web, email [email protected] with your username and we'll remove it within 30 days.
Can I suggest a new game or feature?
Absolutely, we'd love that. Send your ideas to [email protected].
