In Killer Sudoku, every puzzle features cages that tell you the sum of the numbers inside. This extra information leads to beautiful logic that you will master as you progress through our handmade puzzles. The puzzles in Killer Sudoku are created by Simon and Mark as well as a large number of guest creators. Fans of Cracking the Cryptic's YouTube channel will recognize many of these authors as some of the most talented creators working today! As with our other games (‘Classic Sudoku’, ‘Sandwich Sudoku’, ‘Chess Sudoku’, 'Thermo Sudoku' and 'Miracle Sudoku'), Simon Anthony and Mark Goodliffe (the hosts of Cracking The Cryptic) have written all the hints for the puzzles. So you know that every puzzle has been play-tested by a human being to ensure that each sudoku is interesting and fun to solve. In Cracking The Cryptic’s games, players start with zero stars and earn stars by solving puzzles. The more puzzles you solve, the more stars you earn and the more puzzles you get to play. Only the most dedicated (and cleverest) sudoku players will finish all the puzzles. Of course the difficulty is carefully calibrated to ensure lots of puzzles at every level (from easy through to extreme). Anyone familiar with their YouTube channel will know that Simon and Mark take pride in teaching viewers to be better solvers and, in these games, they always craft the puzzles with the mindset of trying to help solvers improve their skills. Mark and Simon have both represented the UK many times at the World Sudoku Championship and you can find more of their puzzles (and lots of others) on the internet’s biggest sudoku channel Cracking The Cryptic. Features: 100 beautiful puzzles 15 bonus beginner puzzles Hints crafted by Simon and Mark! ## Killer Sudoku CTC Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/08/88/5c/08885ca1-7f24-054a-b2d1-d2733256d4b4/cc067263-9a7c-4d17-91b2-cbf329b7222d_screen_1284x2778_2020-12-09_16-09-20.png/1284x2778.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource114/v4/1f/dc/1b/1fdc1b05-d867-9f30-a2a4-8d9c06c91344/bbf5b3fd-e3a7-420d-bb81-99163316a8b7_screen_1284x2778_2020-12-09_16-13-11.png/1284x2778.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource124/v4/0d/2c/a9/0d2ca9fd-9f62-2430-f415-54612a6df55c/bcee5542-e89c-4fda-a983-63040a7bb8da_screen_1284x2778_2020-12-09_16-11-11.png/1284x2778.png) ## Killer Sudoku CTC Rating Breakdown in United States - 5 stars: 61 (80%) - 4 stars: 5 (7%) - 3 stars: 5 (7%) - 2 stars: 1 (1%) - 1 stars: 4 (5%) ## Killer Sudoku CTC Reviews in United States ### *---- "Great games but…" It’s annoying having to replay the same puzzles every time I redownload the app. Sometimes I delete it if I’m spending too much time on it and then I lose all progress. Would much rather have access to all the puzzles at once. -- Joshadik307, 2024-11-09 ### ****- "Almost perfect" The puzzle clears itself the moment you finish it so there’s no time to screen shot the solution. -- tstambaugh92, 2024-08-07 ### ***** "Is it possible to reset the puzzles to play them again?" Love the app, but can’t find a way to reset it and start over again -- Mattimeo84, 2023-01-29 ### ***** "Beautiful! And a request..." All of CTC's Sudoku apps have beautiful puzzles and excellent tools. My only request for their Killer (and Sandwich) Sudoku is to include list exclusion (in the given lists of sums) in the undo stack. I will often run aground and need to undo myself back a bit, and I lose my thread of deduction when the lists I've grayed out don't revert. If this is a known challenge for UX (it might appear that nothing happened), I would suggest showing (and flashing?) the sums panel when undoing those exclusions. I give it 5 stars regardless, but knowing how thoughtful they are I thought I would offer this request for future updates! -- crag__, 2022-10-18 ### ***** "The perfect sudoku app!" 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. -- iestynne, 2022-09-15 ### ***-- "Great layout, but some of the puzzles are poorly rated." 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. -- Greenie213, 2022-07-20 ### *---- "Unusable after last update" Love the puzzles in this app, but after the last update, the app is unusable in landscape mode (iphone 13 pro max). Clues are automatically displayed and when they are, they're just a tall and skinny column that you can't even read. It's a small bug that completely destroys the app's usability. -- Moskowizzle, 2022-05-06 ### ****- "Like it!" 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? -- Egeriis, 2022-05-05 ### **--- "Beautiful app, not so good puzzles" 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. -- Alex-i, 2022-02-27 ### ***** "Great puzzles, Sometimes hints are not understandable" 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. -- Backgammon Master, 2021-11-17 [View all Killer Sudoku CTC reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Killer Sudoku CTC Discovered Keywords -
