Killer Sudoku by Sudoku.com

Obnoxious ads I used to like this game but I elect to no longer play it. The ads are cartoonish game ads that set set loudly and play too long.

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.

Great App They let you play and don't harass you with ads, and the killer sudoku puzzles are top-notch

Daily Challenges Not Killer or Challenging This app used to be great. It was my go to brain break throughout the day. With over 6000 expert puzzles and 2000 daily challenges solved, you could say I was a fan. For the last few months, the daily challenges have all been easy or medium and are a total snooze. I have used this app for years but this recent change has made me look for other ways to challenge myself throughout my day.

Almost great I loved the app until ads started filling every game. I’d be willing to pay a couple dollars for ad free… but 15? That’s crazy

ads ruined it Fun game, good way to kill time. There's one ad that actually just ruins it rn tho. every few seconds one of the banner ads goes full screen and it's basically unplayable

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.

Alex Great game. It develops logic well.

Sub-par compared to other sudoku apps Multiple issues. Can’t adjust the colors of the numbers, making it difficult to read. No option for auto entry of all pencil marks. And the ADSSSSS… Get a phone call? As to return. Accidentally closed to look at another app? Ads. I get there is a paywall, but when you can’t even pay the game long enough to try it out, why would I pay for more? Look for alternatives; there are a ton better apps out there.

JJ The sudoku is good with an added clue for squares. But there are way too many adds and the adds are too hard to get rid of, by the time you get back to the game, you’ve lost your train of thought. Very frustrating.
