Description
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: 100 beautiful puzzles from the Knight, King and Queen variants Hints crafted by Simon and Mark!

If you're not here for the hints, no worries, it's a great app. The hints often are completely incorrect. Hint #3 on puzzle 16 of chess sudoku says you can place a 7 in column 4, but there's 2 possibilities for 7 in the column, in the box, and in the row. I think this also skews the difficulty on puzzles with incorrect hints, usually making them far harder than their star rating as the puzzles WOULD be easy enough if they worked the way the hints suggest.

I love this app! I've always loved sudoku and particularly enjoyed the gradual increase in difficulty that meant I didn't feel like I would fail the "latest" puzzle because it was impossible based on my skill/logic. I'm eagerly awaiting the Queen sudoku puzzles and any more King or Knight puzzles if there are any - so far I think Knight is my favorite.

I downloaded this after watching many of their YouTube videos. I enjoy the knight and king Sudoku, but the queen puzzles are broken. The ones I have done so far ignore the rules for the digits other than 9.

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.

Crashes in launch after I updated to Android 10, so I've been unable to player for 6 months or so.

Don't forget you owe use 5 new puzzles over here as of today or tomorrow as well. I'm worried based on your track record you're going to continue this scam of 5 new puzzles a month at one app or the other. Prove me wrong.

I love the puzzle, and I even watch them on YouTube, they are really fun, but I finished them all ages ago and need more puzzles. Is there any coming soon?
