Sudoku remains the purest, most elegant number strategy game. Most sudoku apps, however, are cluttered with unnecessary distractions. We designed Sudoku Sue for iPhone and iPad to put the focus back where it belongs: on game play. 

Sudoku Sue's first level contains 500 puzzles and is free! Levels 2-5, which contain an additional 2,000 puzzles, can be unlocked for just $0.99.
