Killer Sudoku CTC for Android

Great sudoku app with many well thought out puzzles. One knock is how battery draining the app seems to be. Maybe chosing to build something this simple on Unity was not the right choice?

The app is beautiful, however I don’t like the puzzles so much. Most of them require brute force solving. By that I mean you have to take a guess and keep going until you hit a contradiction, then you guess again.

I enjoy Cracking The Cryptic variations on Sudoku puzzles and spend more time than I’d like to admit playing them. Sometimes when playing the more difficult puzzles, I look to the hints to get insight as to how to solve them. Many times, the hints are vague and do not help to understand the step. I get that it may be text length limited but if it doesn’t help, why bother. Keep making these puzzles while trying to help with better hints for solutions.

The puzzles are well designed and extremely challenging! Unfortunately, if you’re not as smart as the Cracking The Cryptic crew, the in-game hints often seem to be focused on conserving space over explaining their logic, which often leads to hints asserting facts not in obvious evidence, which doesn’t help the user understand what they’re doing wrong.

I’ve really been enjoying this app. It is well made and the puzzles range from easy to very difficult. I’d mostly recommend this. My biggest “complaint” is the hint system. Smart hints are nice, but often will tell me things I already know. “Regular” hints… well they use a lot of jargon and state things that are not obvious and give free explanations. Some puzzles are better than others, but as the difficulty ramps up I’m finding the hints harder to follow. The hint may say these four cells need to be a 6/7/8/9 quadruple or that these two cells must add up to 4, but I have no idea how they got to those limitations. As such, I’m not learning any new strategies. (And sometimes the hints are leave me completely confused.) I did get this app a second time on my android tablet so I could play on a larger screen. Currently the syncing function will sync or merge progress, but it does set your completion times to 999:59 for all your puzzles. (Or at least it did for me.)
