Killer Sudoku by Sudoku.com

2nd Best game ever (Minecraft is 1) I love this game, sudoku alone doesn’t give me enough information and this fixes that. It keeps my brain active. I’ve gotten so good at expert that I’ll play drunk to make it more difficult. My fastest time solving an expert puzzle is 2:46. Might be a world record. I actually hit that PR in the gym. Shoutout to my mom for getting rid of the ads for me.

Great but glitchy Great app, love the game , nice and simple layout, but i have had the same issue for over a year now on 2 different IOS versions. To my understanding the game keeps running ads on the background wich causes my phone to get hot. I have tried with and without other apps opened and still the same issue. I wish they would run some update or bug fix from time to time.

Scoring I've played thousands of times without ever understanding how to score the game. If you make a mistake it's an error in logic or basic math. Sounds easy but it's very challenging. It's a bit crazy how many times I've played. "Expert" is the only challenging level to play.

Two thumbs up! This is a great game. I have worked my way up to expert and I enjoy it every day. I would change two things. First, I would like three hints instead of one. Second, I would like a more thorough explanation of how the scoring is done. It does not seem to matter how many mistakes I make, and I think that should affect the scoring.

Bad app design Too many ads this is ridiculous

No option to increase the fonts Too hard to see the numbers

Sudoku Fun

Great brain exercise I play this every morning to get my 75 year old brain active. I enjoy using a variety of strategies when solving the hardest ones.

Interesting complexity Great Game! Adds a chess like layer of strategy to Sudoku!

Side contests You had me until you forced the expert games in all of your side contests. There should be a separate contest for expert puzzles. Deleted the game when I found out I couldn’t bypass them.
