About Sudoku by Logify
Play Classic Sudoku the most intuitive way: write in the numbers with your finger. Feels just like playing on paper, only better; number highlighting and other features will help you locate patterns without giving away the solution easily.
The game offers unlimited Sudokus in four difficulty levels from easy to expert. Each puzzle can be solved with logical reasoning; no guessing required. If you are new to Sudoku or want to try the next level up, use hints to learn new strategies. The advanced hint system will explain the logic behind each pattern and how to find it on your own. You will see that most of these strategies are not that difficult, even though it may be hard to find them on the board.
Summary of features:
• Number entry by drawing, no number pad
• Use your finger as eraser (left-right-left)
• Double tap to add/clear notes
• Number highlighting, including notes
• Completed numbers gray out (optional)
• Switch between levels anytime, last game saved for each level
• Unlimited puzzles, all solvable, no guessing required
• Advanced hint system designed to teach new strategies
• Auto notes (for hard and expert level)
• Auto complete button (optional)
• Daily Challenges
• Undo/Redo
• Statistics, top 10 times (tap on timer)
• Game Center leaderboard and achievements
• Font, board design, and backdrop options
Enjoy!

- Added Undo until solvable. Here is how it works: when a hint shows a error in the position, you can use this new button to go back to before the first error was made. As often the case, one error leads to another and by the time you notice it, it's easier to go back to a good state rather than trying to fix the position.
- It is now allowed to write over a number to replace it (except for the given numbers of course). The app is not going to warn you though if you accidentally change an already solved cell so look out for that.
- The ink color is now a little lighter to help make the given numbers stand out.
