Blueberry Puzzle

**Blueberry Puzzle** is a minimalist logic game that challenges you to think carefully and plan ahead. Place berries on a 9×9 grid so that: - each row contains exactly **three** berries - each column contains exactly **three** berries - each 3×3 block contains exactly **three** berries Some cells contain numbers. These numbers indicate how many berries are placed in the surrounding cells — including diagonals — similar to classic minesweeper-style clues. The challenge is to combine the number clues with the exact-count rules to deduce the correct placement. ### Features - Clean, distraction-free design - Multiple puzzle difficulties - Visual highlighting of rule violations - Undo / redo support - Fully offline play - No ads, no tracking, no data collection ### Inspiration This app is an independent implementation inspired by the **Blueberry Trio** logic puzzle originally published at: https://circle9puzzle.com/bbtrio/ ### Open Source The project is open source and available on GitHub: https://github.com/AndreyCorelli/blueberry-puzzle-app
