Presented by Cracking The Cryptic, the most popular Sudoku channel, comes a new game based on our most requested variant: Killer Sudoku. 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 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 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!}

Love the app, however, I recently upgraded to a Pixel 10 and started receiving word graphic glitches: blinking screen, flashing, black screen.

After starting to use it on my pixel 10 pro, I have started to encounter graphical errors. Most of which is flashing, blank screen which is partial or full screens.

Almost every puzzle I play I say to my self "this sudoku is so difficult" which is exactly what I wanted, 5/5! The system for writing notes in the puzzle and is the best of any sudoku app I've played

Love it. Hints are really helpful for some Puzzles, But some are Just wrong, e.g hint 2 of Puzzle #96 ist exatly opposite of how it ist written. Box 2 has 3/8 summing to 11 with sum of 12 being Impossible. found that Out after several tries with this Puzzle and trying to understand the hint for it

Great selection of puzzles, good UI, good configuration options. Overall very fun! I'm taking away one star because the pre-written hints are frequently wrong and/or confusing. Hint #1 of Puzzle #22 "45s" is a great example: the third part (about where 8 goes in r1) directly conflicts with the previous part of the hint, and the final part is downright impossible. Of course, this isn't a problem if you never need hints, but some of us do!

This is clearly the best application there is. The interface is so neat and intuitive. These puzzles make you feel really smart!

Great game, the interface and interaction with the cells is the best out of all sudoku apps, they should make one for kakuro. But I have my phone set to not rotate if it detected my face so that it stays oriented the way I want to. Every app stays portrait when I lay down and play. But all your games still rotate to landscape when I don't want them to

I really love this app but I am someone who needs hints and the hints don't always explain how to get from a to b so it often reads like it's telling you point a and then point d. Like one hint is the minimum value in 6 different digits is 21 so this cell must be 1 - but it doesn't actually explain why I care about the minimum value (why not maximum value???) And why that cell must be 1 and not literally any other number. (And that's starting from a blank grid). Just more explicit hints please

Completed it with some hints. Now i feel like i should try and complete them all without them. Best sudoku app I've seen so far!
