The hint system does more than simply reveal an answer. It first shows you where to look, then explains the reasoning, and finally guides you to the answer. This helps you gradually understand how Sudoku puzzles can be solved.
Your completed puzzles are recorded in the Sudoku Journal. You can look back at the days you played and save a short note or memo for each date.
There is no time limit and no game over.
Take your time, think at your own pace, and enjoy a relaxing daily Sudoku routine.
