One game, built deliberately outside our usual domain.

Diagnostic tools exercise a narrow slice of Android: read some state, present it clearly, stay out of the way. They never touch animation, real-time networking, state restoration across rotation and process death, or monetisation that has to work without in-app purchases.

Building something that needs all of those is a reliable way to find out what you have been getting away with elsewhere. It is also why the game exists at all — the alternative was to keep writing the same kind of software and slowly narrow.

The result is a small game with a genuine twist rather than another identical three-in-a-row: each player has three marks, and once they are placed you move them instead of adding more, so the board never fills and a draw is impossible. Everything in it is earned by playing; nothing is sold.
