I actually like the puzzles. The problem is, when I get done, there's no way to get them marked as complete or verify they're done correctly. If you don't sign in,which I have no easier or intention of doing, there's no completion. Rediculous

New to cool sudoku, like the range of games and levels,however having trouble with some of the features. When exit a game my progress isn't always saved; the 'updating possibilities' while playing I find erratic,seems to sometimes work sometimes not...I'm uncertain is this part of the difficulty level? I'd also like more practice games. This is a different sudoku app as seasoned reviewers have indicated. I look forward to the improvements on smoothing out your new design and functionality.

This used to be my favorite app, but they have truly destroyed it!! Cheapened it!!! The original app was so easy to use and responsive. For nearly six years I've done anywhere from 10-20 puzzles a day for speed. Now whenever I tap a number, there's a delay to its appearing in the cell, which makes it hard to work for speed. I hate it. I'm so sad that I have to say goodbye to the old version... Like losing an ol' friend! I will be finding a new killer sudoku app, FOR SURE!!!!

Despise the update! The new design is very difficult to see so I deleted it. Off to find a new one. :(

Could be a five star game but I can never finish a game before all the numbers erase.

Still my very favorite sudoku. Love the Killer Sudoku. Like having a new puzzle every day. Like having rankings for all 6 puzzles daily. Good job, people!

I've always been fairly happy with this app, but recently I've solved are coming up as incorrect. Particularly kakuros. I've screenshot them, run them by several people, I have a working solution that violates no rules. If it had only happened once I'd be OK with ignoring it, but it's happened to two puzzles this week alone.

I tried to solve a puzzle but it was hard to switch from pen to pencil and sometimes it didn't change. It would also refuse to clear a square when I decided I wanted to redo everything in it. I love sudoku but this just didn't cut it for me. I gave it 2 stars because it looks nicer than some of the others out there and the puzzles are adequately difficult.
