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'.

Easy level has now become difficult

With updates, the easy level became very difficult meaning when I'd like to play a quick game, used to take 3-4 min. (Nice while waiting in line somewhere), now takes up to 7 min - I thought it was me until two friends complained about the same thing w this same game. I'll be moving on to another one by a different company. (The 'resume' button isn't obvious either.)

Easy to use

I have used many SUDOKU apps for years. This one is very easy to use in terms of entering numbers and self-deleting notes in whose boxes the correct number has been entered. Great for me since I like to time my games.
