Excellent Game

I really enjoy this version of Killer Sudoku. I’ve played hundreds of games and not seen any that were “badly formed.” Some were truly devilish to solve, and I often think that the expert level could be divided into 2 levels because of the differences in difficulty among those puzzles. Like another reviewer, I also noticed that I got more expert puzzles as dailies as I went along. I assumed that the game learned the players skill level and tuned the game to present appropriate puzzles. If it does not do that then let me suggest it. One comment for improvement is on the Ads. I like the way they are handled and how I can FF through many of them, and I like that they have the Adsense triangle on most of them to allow reporting bad ads. This is especially helpful because there are a set of ads that never exit and don’t provide an X or close button. Those also don’t seem to render properly. On those ads the only thing that works is clicking through to their website or returning to the ad. On them I have to kill the Killer Sudoku app and restart it to move on. Yet other ads lock up my iPad almost completely. I remember groaning over and over when the killer ad came up. It was for drinkable makeup or something like that. I have iPad 4 FWIW.

Hi, thanks for your feedback. Yes, you are right, the Daily Challenges are generated randomly and the difficulty level may vary from one game to another, but they take into account the difficulty level of usual games you play. Would you please give us the screenshots of these unskippable Ads? Please provide this information using the “Help” section inside the app, or at support[at] We will do everything to reveal the advertiser and appeal a complaint if necessary

Yes a bit harder

If you are a regular player of sudoku and have never played this version before, start out with medium.. then work up to hard. That one is challenging but keeps your brain active. Using a combination of regular sudoku rationalizations, and the new ones you learn in this version you can solve all of the hard. The boards are well done, easy access to hard choices and for notes. I love how it eliminates numbers that are completed, and highlights choices. The software also keeps track of your records, losses and wins, how long it takes, scores, and such. The background of the game is simple…the developers could add a color back ground, art, to add more value. If you want to move to expert level, be sure you Google this type of Sudoku and learn how to use the 45 methods. That’s challenging! Great job.
