Killer Sudoku CTC App Reviews

Love the app, but can’t find a way to reset it and start over again

Killer sudoku are IMO the best variant, due tom the sheer variety of logical techniques the setter and solver can explore. These puzzles are really fantastic. Every one is thoughtfully crafted, each infused with a delightfully unique structure and narrative. The puzzle interface is simple but effective, with a sophisticated hint system designed to teach new solving techniques. All in all this app feels like a labor of love. Couldn't recommend it more highly.

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.

Best interface of any killer sudoku app on the market. Big problem, though. The puzzles authored by “Cracking the Cryptic” are much more difficult than puzzles rated similarly by other authors. Since this was developed by CTC, it would seem that they are not good judges of their own puzzles. It leads to random difficulty spikes that are frustrating for players like myself just learning the ropes.

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?

CTC sudoku apps are the only sudoku apps worth installing. High puzzles and apps, should be the first (and only) stop you make when looking for new puzzles to try

The app is beautiful, however I only got 40 puzzles. How do I get more?

The calculator is awesome and the list of choices that you can filter helps so much. I hope that more puzzles are added soon!

I love everything Cracking the Cryptic puts out. Not only are the puzzles fun to play over and over, but their “hints” are also great at teaching how to be better at the puzzles.

Love this app, really challenging but fun killer sudokus to play! Only criticism I have is adding new puzzles. Hoping for more puzzles to be added but love it regardless. Let’s get cracking!

The quality of each and every one of these hand crafted puzzles is superb. I look forward to the next update!

Wonderfully challenging games that will keep you binge playing for hours

The utilities in this app along with the beauty of the puzzles make it perfect for me to grow in my sudoku solving skills. I can practice more of the solving techniques seen in the CTC videos. It is a joy.

Fantastic app! Easy to use and lots of options to customize the gameplay. Puzzles are TOUGH, but each has a set of helpful hints that teach you tricks to learn from.
