Installing in three steps

1. Download the APK from your invite. Chrome may warn that APKs can be harmful. That warning appears for every app installed outside a store, including this one.
2. Allow the install. Android will ask you to allow installs from your browser, one time only. Settings, then "Install unknown apps", then allow.
3. Open the game. Create your account and begin your record. Updates are announced in the app and can be installed over the top, nothing is lost.

Playing on iPhone?

iOS is coming. Leave your email and you will be the first to know, nothing else will ever be sent to it.

Honest answers

Why is this not on Google Play yet?

The game is in open beta and moving fast. Distributing the APK ourselves lets updates ship the day they are ready. The store release will use the same account system, so nothing you earn now is lost.

Is it safe?

Every release is signed with the same developer key, and its SHA-256 checksum ships with each build. When the public download opens, the checksum will be published on this page so you can verify what you installed.

How do updates work?

The game tells you when a new version is out and links you back here. Install the new APK over the old one. Your progress lives on the server either way.

What does it cost?

Nothing. The beta is free and there is no pay-to-win.
