Best free Soduko App I've found

Four levels of difficulty, but only a limited number of puzzles.

Some nice feature options: choice of color schemes, correct/incorrect indicator, and 'notes' which puts small numbers (for possibilities) on a 3x3 grid in each box which are then erased as each possibility is eliminated.

Would like an 'automated entry' feature which would automatically enter the last remaining possibility in a box. What I mean is that 'notes', the possibilities you entered in each box, are reduced as they are eliminated by other boxes being solved, but when only one possibility remains you must manually enter it as your solution for that box. I want the option for the final possibility to enter itself, so that they would 'fly', reducing the tedium of the 'hunt and peck' of doing them one by one - after all you already went through that making the 'notes'.

Fun, But Add More Games

This is my favorite sudoku app. It’s fun and keeps track of your best time and average time. When you make a correct selection, it removes that number from any conflicting possible fields you have marked. There are literally NO ads, so it’s not a money maker for the developer, which may be why there seem to have been no new games added. Two games frequently pop up, which I now skip, because I realized I had memorized them through repetition. The last update was three years ago, so it looks like no new games will be added.

Great Game!

Have been able to do all 10 in each level... now working on setting best times... been awhile since playing, and set two best times today...

June 5, set a new best time today, would like to see deeper analytics as to time of day, when records were set, I believe I’m sharper in the mornings, than later in the day... thanks for all your efforts.

Still working to beat best times, and lower averages... hesitant to clear past games, as is interesting to see averages continue to drop...
