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help, the optional smart notes feature automatically deletes values from notes you have entered manually when they are no longer valid.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

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.

Restore purchases??

I have enjoyed this app. I finally bought a couple (Taison & Sakai). It stopped in middle of game. Now games I have not worked are marked as completed & reversed with those I have not completed?. It will not let me restore purchases. When I got new iPad it would not restore purchased games I previously had then either?There is a tab for this (restore purchases)but it Does not respond. Must be there for Looks! I would give it five stars if I could use what I had bought and these new ones just worked correctly! Not worth anything to buy added games. Just stick it basic set & replay them.

It's a good game, but has flaws

The game is fine, and easy to use. It took me just a couple games to get a hang of how to fill in the hints.
However, it comes with just 100 games before you need to buy an expansion pack. I flew through the first 100 games in under 3 days.

Also, in the most recent expansion pack of "insane" games, the whole game crashes, repeatedly. This wouldn't be a tragedy, except for the fact about half the progress is lost.
My games are also crashing 5, 7, 12 times before I can finish them.
I had a record of under 8:00, but with having to restart multiple times my average is now around 22:00.
It's very, very frustrating.
I am about to delete the whole silly thing. There have got to be other sudoku games that don't crash in every game.
