A recent update has made “easy” the only games that can be solved. I wish I could go back. I used to get through medium games in about 10 minutes. I rarely did hard puzzles and I rarely did easy puzzles. No easy is the only puzzle that can be solved and I’m losing interest in a game I probably played for more than 10 years

I have been playing and enjoying this Sudoku game far more than any other version I’ve ever tried. It is a great way to kill time in a waiting room, and I always strive to complete a game in the shortest possible time, which up to now is 4:38.

However the latest 2.1 version changed the difficulty algorithm and now I am finding that some the “easy” difficulty games impossible to solve without guessing and using the guess if correct.

They need to reexamine the new difficulty algorithm and revert back to the previous version since it appears version 2.1 generates some “easy” games that can’t be solved without guessing.

(As a rule, even the most difficult game should have a unique solution that is discoverable by the constraints without guessing, where accepting a hint should reveal the overlooked constraint that forced that choice, and the only difference between easy and hard games being how obvious the constraints are.)

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'.
