The only sudoku game to reach the top of the app store charts. Has been ranked as the #1 app in the overall iPad chart in 10 countries including the United States. A top 10 game in 72 countries!

Its been called the "Best Sudoku Game on ANY platform". Sudoku Book is an essential game for every iPhone or iPad. Its been featured by Apple in Whats Hot, New and Noteworthy, Game Center Games, Game Starter Kit, and recently in Popular Puzzlers.

If you like Sudoku you have to try Big Bad Sudoku Book. Its our opinion that many other versions of the game sort of take the fun out of it. They wont let you enter in wrong numbers, and if you ask for a hint they straight up give you the answer to a cell. Why not just put up a puzzle and solve it for you? Ill tell you why, cause thats not fun! Our approach is a lot different. Our hints guide you to answers without flat out giving it away. We provide the tools you need to solve the puzzle with your brain, just like a real paper sudoku book but better!

*** "If Apple made a sudoku game I think it would look like this" - Dytavio ***

Change The Look!! Version 3 adds a fun twist on the classic game with new downloadable themes and challenging new puzzle book campaigns. But this is not a freemium app.. Sudoku Books core functionality is all included. It has unlimited free play in all levels and all the same features as the previous version plus more.

*** "The whole look is perfect... This is the best sudoku interface of the five sudoku apps I have downloaded. I suspect the rest will be removed from my iPad" - GrayerBeard ***

Puzzle scoring brings an arcade game feel to sudoku and provides a metric for challenges. Sudoku Book uses an exclusive method of scoring games based on the difficulty of each answer - not based on time. Now there are two parts to the puzzle, how to solve it and how to get a higher score.

We listen to our users and have added many features based on user requests. Tech support is available within the app as a direct email to the developer. And we respond. Already in version 3 weve been in contact with many users and are fixing things based on their input.

*** The "Best Sudoku got better. Still the most like pen and paper. I love the interface. New changes made the best better." - pluto6 ***

Sudoku Book 3 adds new puzzle types and a new difficulty level. All puzzles are guaranteed to have a single solution and be solvable without guessing. Harder puzzles do require some advanced solving techniques.

Also added are many new user requested features like auto removal of marks, number counts (how many of each number is on the board), and the ability to turn off manual highlighting and the mistake smudges.

Optimized for the iPhone5 screen!

Pros and cons of Big Bad Sudoku Book app for iPhone and iPad

Big Bad Sudoku Book app good for

I like this Suduku game best of all I have tried. I have played it regularly for more than a year. I only play Insane puzzles. They are just hard enough to give me the sort of challenge Im always looking for in any game. I like the new feature of automatic erase in the other cases when making a fixation of a digit. However if that fixation was wrong you have lost in wich other cases you had put that particular digit. I also think there should be a gap between the two tables of digits you are choosing from, too easy to make a mistake. It would also make more sense to have them presented as two rows, one below the other instead of the table format. I only play this game on IPad.

This is by far the best sudoku game available for the iPad. If you like sudoku this is the one to buy!

Super fun, love sudoku. Best think before bed so relaxing :)

Love this game,just got my first expert solved,although I am sticking with the hard level.My wife and I spend more time on this great App than anything else.

Very well though out game. It would almost be perfect if either I did not have such fat fingers or the grid for entering possibilities was a bit larger.

I have played so many insane games, my wife thinks that I am.

Some bad moments

I have a difficult time with the in-game advertising. Its intrusive, jarring, opportunistic, and structured to drive you to the AppStore accidentally. Too bad because I really enjoy it otherwise.

Maybe a good game, but the user interface is frustrating. I kept apparently hitting multiple numbers in the pencil setting when trying to pick one. Ive never been accused of having fat fingers before, but it seems I do for this game. That leaves me having to figure out what was pencilled in before. Frustrating. Not something I have experienced with other sudoku apps.

Nice, addictive game but the other books are not available to purchase. Any clues why?

I have had this sudoku game on my iPad for years and love it. That being said, just got a new Ipad and downloaded again and I really dislike the new "smaller" number version. Very disappointed and now I dont enjoy any longer. I do not have large fingers but really folks? This is ridiculous!

I had to temporarily delete & when I reinstalled all of a sudden I get these pop-up ads before each game. Very frustrating. Can I get rid of them?

The newest update has ruined this game for me. I cant seem to turn off the new defaults and it is horrible. Completely unplayable. Every blank square populates with ALL NUMBERS, including the ones that are impossible in that square. In addition the yellow highlight on rows and blocks is irritating and unnecessary. Please fix this. This is unplayable.
