What Makes Sudoku by Logify Stand Out
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)

• Font, board design, and backdrop options
Enjoy!
This Board game offers engaging gameplay and regular updates for mobile players.

Community Insight:
Drawing numbers with your finger is a pain in this version. We give it 0, bring back number selection.
Handwriting recognition is a nice feature, but it frequently confused 8 for 9, and occasionally mixed up 6 with 9.
This is fun and more like how youd play with pen and paper but you lose time rewriting a number over and over as it tries to interpret what youve written. Even at the very end when theres only one choice for a number it will waste a bunch of your time saying youve written for example a nine instead of a five.
The finger writing feature makes it much like playing on paper. The hint is excellent to help us learn the tricks. After a few weeks playing, we are at medium level now.
This is the best Sudoku game on the market… By far! We like that we can write our numbers directly on the screen.
So far our favorite sudoko app, we love that we can write in the numbers, its refreshing from all the other apps where u have to select the box then select a number. Erasing is easy with a double circle. Our only issue is the notes. You give us only the numbers that CAN be notes, which is a border line cheat. For notes ALL numbers should pop up and we choose the note. Other than that great app. Please consider the note fix in your next upgrade. Coming back for an update still our go to sudoku app, this app could be the number #1 app in the puzzle category but they dont even care we believe. Its absolutely fun being able to write the numbers.
Wish we could erase a number after playing one after mistake.
Would be nice if this feature truly did not allow any errors not just 'invalid entry' inputs…minus for us.
We actually like the game. Only thing we dont like is the notes. We want to enter our own. We dont like that it shows us all the unplayed numbers and then we have to get rid of the ones we dont want to show. We dont enter notes until Im pretty sure its down to just two possibles.
We love to write the numbers directly into the cells. Great feature.
This is a really great app that lets you write the numbers instead of tapping or typing them, and the interface is slick. Since we can already write the numbers would it be possible to add coloring so that we can make our own notes in different colors for Medusa and other strategies? That would be awesome.
The last version was better. At least you had something to earn in the number of hints you could bank. Now there is no incentive.
Great app, however it will allow errors even though its set to not allow. Somewhat confusing.
Excellent and addictive! Love this game.
If you fill the board with ones, it says you win. Also removed typing and ability to leave notes… This was much better before the updates.
This is a fun game. We like being able to right the number with our finger.
This is a good, fun, time killing app. However, the motion control for trying to erase a wrong number, keeps thinking that you are writing another number. So what should take you one shot, takes multiple times of erasing the same number until it realizes you want to get rid of it. Maybe there should be an added button or even to be able to circle the number and have it delete? Otherwise, its a great app.
Good features to get better at sudoku (ourselves a newbie). We can see it being fun for experts too. Handwriting feature is nice – but probably even better on an iPad.
