About Sudaku

Sudaku helps Sudoku players work through puzzles by expressing patterns as constraints, including all-different, one-of, and value elimination. It applies the obvious consequences so players can focus on the next deduction.

It includes 9×9 and 16×16 puzzles. The app is available through F-Droid and the project repository.
