Handcrafted Chess Sudoku puzzles by YouTube's most popular Sudoku channel!

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.

Victoria Eshelby

So now having completed the chess Sudoku series, I would say this was worth the buy. Not only is each puzzle ~ 14 minutes long (as the average player) to solve there's approximately 85 puzzles. I found the knights and kings version the most enjoyable to solve but definitely felt more accomplished after the queen's because I employed tactics that have been shown in CtC YouTube channel. Great job Goya Team, I do agree with the battery life depleting like crazy though. Can you work on optimizing?

4*, love it. One star is missing only because the game doesn't ask you if you're sure, when you misclick "New game", after spending a week (some hours) with a sudoku and are really close to getting it. This goes to all your sudoku apps. Please put a confirmation to the "new game" if you already have a game started. It's very frustrating when your fat finger touches wrong places.

No new puzzles in over three months, despite the promise of five new puzzles a month. Really disappointing. Update: after over 5 months, 15 puzzles have been added.

★★

Real fun, but drains my battery in mere minutes. Would not recommend because of it.

I was really enjoying the app but for some reason, since my last security patch, it just crashes immediately when I try to launch it. I rebooted and completely uninstalled and reinstalled the app but that didn't help. As is, I can only give this 1 star since it won't even run. Will update if issue gets fixed.
