This review is from: Sudoku Unbound #1 (Kindle Edition)
Enjoyed the challenge. Disappointed when all 100 puzzles are done, cannot delete all answers and start again. Can delete individually however, just takes time. With 100 puzzles, there is no way you are going to remember all correct solutions, so why not redo?
