About Chess Sudoku
Presented by Cracking The Cryptic, YouTube’s most popular Sudoku channel, comes a new game that connects two of the world’s biggest mind games: Chess and Sudoku!
How does Chess Sudoku work? Well we’ve taken the classic sudoku game everyone knows and loves and created puzzles with chess-related twists! There are three different types of puzzles in the game: Knight Sudoku; King Sudoku and Queen Sudoku (coming after launch as a free update!).
In Knight Sudoku, in addition to the normal rules of sudoku (no repeated digit in a row/column/3x3 box) a digit must not appear a chess knight’s move away from itself. This simple extra restriction introduces lots of clever additional logic that makes the puzzle even more interesting!
King Sudoku and Queen Sudoku work the same way: ie it’s always normal sudoku but, in King Sudoku a digit must not be a single diagonal move away from itself; and, in Queen Sudoku, every 9 in the grid acts like a chess Queen and must not be in the same row/column/3x3 box OR diagonal of any other 9!
As with their other games (‘Classic Sudoku’ and ‘Sandwich Sudoku’), Simon Anthony and Mark Goodliffe (the hosts of Cracking The Cryptic) have personally crafted the hints for the puzzles. So you know that every puzzle has been play-tested by a human being to ensure that the 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 to be better solvers and, with their 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 from the Knight and King variants

Saw this recommended on YouTube. I wish the YouTuber or developer would update the app with his recent ultra hard challenges. Or combine the modes for even more challenging arrangements. That being said this format has spoiled me playing soduko. I love the game modes and controls.
Great app, lots of good hand-crafted sudoku. Ignore all the people pointing out issues with queen sudoku, they've all just misunderstood the rules, despite the fact that they're clearly explained in the app itself.
Great app for variant sudoku
Hours and hours of unique and challenging puzzles worth the price and love the new queen soduko addition ⭐⭐⭐⭐⭐
Tricky but in a good way. Makes you see sudokus very differently
Well worth the price. Even after finishing every puzzle, I went back and tried and tried until I got times I was happy with. Got quite a bit of play time out of it.
