## Description

Chess Sudoku, presented by Cracking The Cryptic, pairs chess and Sudoku in three twists: Knight Sudoku, King Sudoku, and Queen Sudoku. Each variant uses standard Sudoku rules with additional chess-move constraints—Knight Sudoku forbids the same digit a knight’s move away, King Sudoku restricts diagonal movements, and Queen Sudoku prevents any 9 from sharing a row, column, box, or diagonal with another 9. Puzzles are crafted by Simon Anthony and Mark Goodliffe and play-tested to be engaging and solvable. Players start with zero stars and earn stars by solving puzzles, unlocking more content as they progress.

August update adds 15 new King puzzles, bringing the total to 100 puzzles across all variants. The game is designed to challenge logic and improve solving skills, offering a satisfying blend of mind games for fans of Cracking The Cryptic.

## Review summary

Chess Sudoku blends chess constraints with Sudoku to deliver fresh, puzzle-rich gameplay. Reviewers praise the three variants (queen, knight, king) for adding depth, the robust solving interface with color-coded notes and multiple-cell selection, and the overall design and value for money. The app is seen as high-quality and addictive, with a supportive community and helpful hints. However, recurring criticisms include inconsistencies in applying queen rules in some puzzles, small number buttons and a non-intuitive notation/entry system, and a fiddly UI for color highlighting.
