About Killer Sudoku

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.

Features:
  • 40 beautiful puzzles on launch
  • 100 puzzles in all with regular updates to reach this total in the first year post launch.
  • Hints crafted by Simon and Mark!

Killer Sudoku, developed and published by Studio Goya, is a meticulously designed logic puzzle experience that expands on traditional Sudoku by introducing a layer of arithmetic reasoning that significantly deepens the challenge. While it retains the familiar structure of filling a 9×9 grid without repeating numbers in rows, columns, and subgrids, it adds a defining twist through the use of “cages”—outlined groups of cells that must sum to a specific value. This single addition transforms the entire solving process, turning each puzzle into a balance between numerical combinations and spatial deduction. The inclusion of cages reshapes how players interact with the grid. Instead of focusing solely on where a number can or cannot go, players must also consider how groups of numbers combine to meet specific totals. This introduces a new layer of logic that operates alongside traditional Sudoku rules, requiring careful planning and constant evaluation of possibilities. Early puzzles ease players into this system by presenting smaller cages and straightforward sums, but as the game progresses, the complexity increases dramatically. Larger cages, overlapping constraints, and tighter mar…

This game is Killer'. I have tried actual Cage Sudoku (is what's really called) on from a paperback book over a decade ago and didn't get it. I needed a computer program to show me. Since i ama from the showme state. WIth no concept of reality without something like this to help me. However i would say that this is a good game. I want to give it a 10 out of 10. However I am still unsure after everything that i have been through with the previous titles along this line i have meticiouslyously reviewed. Perhapse i can easily give Killer Sukudo 9.5 Killers out of 10 Killers. No sound. Who cares when you are being killed by these killer sukduko puzzels! No cloud saves. It doesn't matter if something bad happens to you and or your PC. Who cares if your Laptop gets stolen while on vacation. Just start the freak over! From scratch! Pretend it is the same as not fast traveling in Morrowwind. Except on a critical issue. The cages are neat. It gives me something else to do in life. Which is fine. Most other games are depraved. However this game. Is interesting. Not much of a story/story line. But the plot is relatively good. I would spread this game. It is a good gam…
