1. The “mistakes” display on the board has been upgraded to a “lives” heart system. 2. Added an “Auto-Check” toggle, which can be switched anytime in Settings or during gameplay. When enabled, it keeps the original instant error-checking logic; when disabled, you can fill in numbers more freely—mistakes won’t be flagged immediately or cause a failure, and correct numbers can still be modified. 3. Further improvements to the board experience: when Auto-Check is enabled, correctly filled numbers will automatically clear corresponding notes in the same row, column, and 3×3 box. Clearer hints and Sudoku rules have also been added. 4. Daily Challenge experience upgraded: regular users can view records from the most recent 1 day, while Pro users can unlock up to 6 days. In history, completed challenges can still be reviewed, and unfinished challenges can now be continued.
