The best

I find myself working sudoku whenever I come across a puzzle. And this app lets me work an infinite number of puzzles whenever I want. The included puzzles come in quite a variety of difficulties. And the tutorials help me learn to solve more and harder ones.

I like that I can quickly add a puzzle with the Scan feature. No more abandoning a half-done puzzle when it's time for my appointment or the plane has landed. If someone else has started it, I can enter it by hand, too. (But then I don't get a time result.)

Some of my friends were concerned about the "pencil" notes. They said they had a system for entering them. In every case, it turned out that the system in Sudoku Joy was the same as the one they used.

I have been using the free version for over a year. The ad field across the top catches my eye, but doesn't ever interrupt play.


Play this all the time. Interface takes a little figuring out, but is very usable once you get used to it. Ads not too annoying. Can be depressing, though, as it tells you how much faster everyone else is.

Fantastic Sudoku game!!

This is the best Sudoku game I've found! It gives lessons, allows many different levels of play, and the entertainment value goes on and on and on!
Enough said...I'm in the middle of a puzzle! Buy it now and you too may hate to put it down!
