Sudoku Free!

By Optime Software LLC

Take a journey to feudal Japan with Sudoku Free! With beautiful graphics and killer features, Sudoku Free! is the best Sudoku app available for iOS.


Two separate keypads, one for entries and one for notes, allow you to enter values quickly and easily. No more tedious switching between entry mode and note mode to complete your puzzle.


The optional auto-notes feature enters all of the notes into the puzzle for you and keeps them updated as you solve. If you don't want that much help, the optional smart notes feature automatically deletes values from notes you have entered manually when they are no longer valid.


The optional error checker tells you when you have entered an incorrect or illogical value, allowing you to catch errors early and preventing needless frustration.


Five difficulty levels, from easy to insane, ensure that you will be able to find a puzzle that matches your skill level. With 3,000 total puzzles, you won't run out of puzzles any time soon.

Customer Reviews

Sudoku, by far, one enjoyable, challenging games to play!!

I absolutely love this game and THIS version. I was hooked the first puzzle I ever played! It took awhile too get the hang of it but once I did, I couldn't stop! You have to be precise with every number you place in a box or else your whole game puzzle is thrown off!! So exciting! You can start off with easy games and progress to extremely difficult ones. Once you play 100 games you can easily purchase the next set of 100 for only .99 cents. What a deal. You've got to at least TRY this'll love it too!!! Enjoy.

My favorite game!!

I love this game. It starts you off on the easiest level then gradually builds in intensity all the way up to insane, 100 games in a pack. And it's only .99 to buy the next pack. I limit myself to one new game per day, but I look forward to playing it every day. What's great is that if I want I can go back and replay the games over and over again. Great entertainment!! Thank you so much for such an enjoyable game!!!

Numbers Up

A decent setup and fairly easy to play. I wish the autocheck feature would warn you to a bad number all the time and not just on doubles. And i extremely dislike that hint numbers don't autoerase when that number is used elsewhere.
All in all
It is okay. Not the best but far from the worse.
