Restarting in that state also asks first instead of silently clearing the board.
The games:
* Tower Defence — four towers, three fixed maps plus a daily map, twenty waves and an endless mode
* Sudoku — four difficulties with a guaranteed unique solution, notes, hints and a daily challenge
* Minesweeper — no-guess generation, four sizes, chording and flags
* Dots and Boxes — two players on one phone, or three levels of AI
Around the games:
* A daily challenge that is identical on every device, with no server at all
* A weekly offline league with five tiers
* Over thirty awards
* Stats and a profile
* Persian, English and Simplified Chinese interface with light and dark themes
On privacy:
* The only permission the app declares is vibration. Not even internet access
* No ads, no in-app purchases, no analytics, no tracking
* Every asset ships inside the package. Even the sound is generated with WebAudio, so there is not a single audio file in the build
* Progress is stored on the device only, and Google auto-backup is turned off

If your phone is set to Chinese, the app now starts in Chinese.
In settings, the language and theme pickers no longer overflow their card on narrow screens.
Sharing a result now sends a picture of the finished board, not just a line of text.
The result panel has a close button, so you can look at the board you just finished.
Minesweeper: the board sits in a real frame with curved corners.
Tower defence: towers are built from a permanent bar instead of a popup.
Thirty-five other fixes across all four games.
