Sudoku Free HD

By Optime Software LLC

This app is only available on the App Store for iOS devices.


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


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help, the optional smart notes feature automatically deletes values from notes you have entered manually when they are no longer valid.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.

Download Sudoku Free HD for free today and start playing Sudoku the way it was meant to be played!

Great game!

I've been playing this game for quite a while now, and it's one of the best values in the App Store. You get some puzzles free with the app (I don't remember how many) and additional puzzle packs are 99 cents for 100 puzzles. That's a penny a puzzle. They take me between 10 and 20 minutes for me to solve usually, depending on whether I mess up and have to start over. A penny for ten minutes of entertainment is unbeatable. And the design is excellent, both in terms of appearance and ease of use. Unlike paper, you can easily remove choices and manage "possibles."

If you like brain puzzles or Sudoku specifically, get this app.

Update. I still love this game. Just had to come back and say that.

Good - could add a few features

Overall, I think this is a very nice edition of a Sudoku puzzle game. I would like to see 2 specific things added - one, something to show you when all of the number has been used in all nine squares and I would like to see them remove the penalty for mistakes. Most of mine are silly and I don't think it should matter. Or offer an option that elects to highlight mistakes with a penalty or NOT show a mistake and NO penalty..

WARNING: Coin purchase overrides Apple's cash restrictions!

Love the game, but today when I purchased puzzles with 100 coins, Apple charged me cash! My purchase restrictions were on, I hadn't purchased anything so the 15 minute rule didn't apply, the game said I was using 100 coins, I was not asked for my password, and Apple didn't ask for purchase confirmation. That means there's a major bug that can override all of Apple's purchase restrictions. Beware! (Apple is refunding, but it could be a major problem for users.)
