A chess game with randomized moves
About this app
Open Chaos Chess is a variation of chess where you can pick the piece that moves, but the moves are random. As such, you no longer win by checkmates. Instead, you win by eliminating your opponent's pieces. The game functions completely without any internet connection, but Bluetooth is required to play the multiplayer mode. Achievement data and colour settings are saved locally.
ACCESS_FINE_LOCATION permission is only used as a mandatory prerequisite for Bluetooth functionality. No location data is stored or sent anywhere by this application.
READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions are only used for import/export of color preferences and achievements.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be dev.corruptedark.openchaoschess is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.9.8 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Open Chaos Chess first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Open Chaos Chess, and a listing is removed when the evidence for it stops holding up.
