Description

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.

DUAL KEYPAD ENTRY

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.

SMART NOTES

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help, the optional smart notes feature automatically deletes values from notes you have entered manually when they are no longer valid.

ERROR CHECKING

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.

MULTIPLE DIFFICULTY LEVELS

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

Oh! That's what's up there! ,

Used to be great

Great interface & really enjoyable to play on my old phone. But trying to play it on my new phone is impossible as it's been hijacked by some other war game app (with no way of closing this). Pity - if I can't get this to work again will have to delete.

Not hard enough but still fun

An enjoyable game with an interface that works very well, but it isn’t hard enough. Though they do take some time, I can get through an insane level without taking notes (that is, using the right side 9 numbers). Fair enough on an easy level, but insane should make me sweat.

Despite that I enjoy it. Mind you, I did pay to turn off the ads and get more levels. If I had to see ads I would hate it.

Good game ruined by latest ‘upgrade’

This was one of my favourite games — played daily. Recently (February 2024) they have introduced changes which are simply horrible. For example, selecting a square makes the whole row or column shaded out with poor contrast — a strain on the eyes and difficult to read. Differentiation has been reduced between left blocks of ‘final’ numbers and right blocks of ‘possible’ numbers — again making it visually less helpful.

Please, PLEASE, revert back to the previous excellent version. You don’t need to fix what ain’t broke.
