The customizable Mastermind clone
About this app
MasterMindy is based on Mastermind, a turn-based code breaking game. The app will generate a secret code for you to deduce. You will only receive minimal hints. A black hint means you positioned a pawn perfectly... but which one? A white hint means one of your selected pawns is correct but in the wrong place. Play alone or with friends to try and solve this puzzle. You can easily change the difficulty on the settings page.
Game Features - Scaling orientation changes on the fly for phones and tables - Flexible amount of pawn fields - Flexible assortment of pawn colors to choose from - Difficulty change for allowing duplicate colors in the secret - Ability to show collision sensitive startup hints - Save-game ability so that you may continue another time - Various time and turn limiting capabilities - Drag & drop pawns on long-press - Option to disable screen sleeping while you think about your turn - Uniquely named pawns for color blind people - Translated into various languages: spanish, portuguese, german, french, polish and dutch - Bitcoin donation ability :)

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 eth.matteljay.mastermindy 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
No earlier build is on record for MasterMindy, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
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 MasterMindy, and a listing is removed when the evidence for it stops holding up.
