About this game

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

Ratings and reviews

I will go to a 5 when there are a few fixes. When you enter a number with the setting on the removes restricted notes, hitting undo does not replace the notes. If you accidentally enter a wrong number, important notes may diappear without you realizing it, leading to making more mistakes due to the now faulty notations. The other issue is that sometimes the game wont let you undo at all, perhaps after changing a game settings option.

Really tough puzzles. There's some really neat logic and it can be fun. But when I get stuck, the hints aren't always very helpful. Sometimes they can be rather cryptic (see what I did there?) and I have no idea how they came to the conclusion they did. They also tend to use run on sentences which can make it harder to understand, and I'm a native English speaker. With the puzzles being so difficult and hints not very helpful sometimes, -1 star. Still a good app.

I genuinely loved this app, and was in the middle of playing through the puzzles a second time (after enough time had passed that of mainly forgotten the details) and then the GUI changed and I find that I just can't get used to the changes. It also feels like every action takes a split-second longer to register (new animations? a pause? don't know). And in a game with a timer, that's a bad deal. I'm sad to say, I'm not sure I'll be playing this again. If you start fresh here, it will be fine.
