***** APRIL UPDATE *****
40 new standard puzzles + 15 bonus beginner puzzles
Presented by Cracking The Cryptic, YouTube’s 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 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.

Ratings and Reviews
Another great entry with good app improvements
I’ve been a big fan of the Cracking the Cryptic apps, and this one is the best iteration so far. The author line up is great with Christopher Seeliger leading off the puzzles. The killer cages are easily visible, and the themes are a good mix of colors. Like the Sandwich Sudoku app, there is a column to show possible combinations in cages for those of us who struggle with mental math. There are 40 puzzles to start, which I think will keep most solvers busy for a bit. The only downside was I was hoping there would be some little killer puzzles, but it doesn’t look like there are any. That’s a bit of a nitpick since that was never really promised, but it would have been fun to see since combo killer-little killers are quite fun. In case case, this is well worth the money. Another great addition to the CtC app collection.
Not your average killer sudoku
Killer sudoku is my favorite sudoku variant, and when I heard Cracking the Cryptic was releasing their own app, I was thrilled. As with their other apps, every single puzzle is hand-crafted and tested, and the creators themselves have written a series of hints for each puzzle that not only help you find the next step if you’re stuck but actually teach you techniques to improve your skills.
Every puzzle in this app is absolutely extraordinary. They’ve been constructed by some of the world’s best setters. This is NOT your average killer sudoku. The logic involved is unique and exciting to find.
Plus, the app has every feature I could ask for in a sudoku app: double notation, your choice of error-checking options, the ability to highlight and color, undo and redo. And specific to killer, it will add up cage totals for you, and it gives a list of all possible combinations for a given cage, and has a calculator for you to test other combinations. It’s a magnificent app, and well worth the $5.
My only real complaint is the occasional typo in the hints, but it hardly mars the overall experience. Also, if there were a way to view the hint and the grid at the same time, that would be helpful.
I really appreciate all of Cracking the Cryptics sudoku apps, and this is one of my favorites. I enjoy that the puzzles in the beginning teach you the particular logic that you’ll need for more challenging puzzles (like how the first puzzle teaches you to use The Secret).
One aspect I really like is the app does a lot of accounting aspects for you, like giving you possible combinations for a given killer cage along with a calculator, plus automatically removing pencil marks that a placed digit interacts with. That is the developers respecting the intelligence of the solver; the challenge is deductions, not getting buried under your pencil marks or petty arithmetic.
Top notch app, hats off to the setters who contributed and the development team.
