Evaluation
Chess Sudoku launched on March 2, 2020 with 40 puzzles across Knight and King variants. The store description at launch noted that Queen Sudoku puzzles were "coming after launch as a free update," and the features list promised "frequent updates adding new puzzles." Both commitments were fulfilled: Queen Sudoku puzzles were added as a free update, and additional King puzzles were added over time. On August 25, 2021, the developer published an update adding 15 new King Sudoku puzzles and announced that all 100 puzzles are now available — explicitly framing the post with "all 100 puzzles are out now!" and "thank you for playing." This language signals the completion of the planned puzzle content. There have been no developer communications since August 25, 2021, and no further content has been announced. The game appears to have launched with a defined content plan that has since been fully delivered.
Evidence

About this game
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.
