Chess Mates
(Published on 3. December 2025, 17:10 by Sudonym)
Cryptic sudoku based on chess moves. Quite hard I think but maybe not for the smart people on this site. Link to puzzle.

There is a video solution on youtube channel "sudoku spot" if you get stuck.
Normal sudoku rules apply. (1-9 in rows, columns and regions) This is a chess board with an extra queen. 1 and 9 are castles. 2 and 8 are knights. 3 and 7 are bishops (Bishops can be on black or white squares). 4 and 6 are queens. 5's are kings. Numbers in the corner of cages represents, moving one square at a time, the shortest number of moves it takes for the piece in that square to reach their nearest mate - another square with the same number (assuming they must move as they do in chess but one square at a time so for e.g. a bishop could change direction diagonally on its second or third move. A queen could move orthogonally then diagonally.) Numbers in the corners of the knights cages represent the shortest number of jumps to another square with the same number (assuming they must move as they do in chess)
Solution code: Column 9

Yes that is correct.

By "number of moves" you mean all pieces except knights move only 1 tile at a time

Super fun puzzle! Combined two of my favorite hobbies: Chess and Sudoku. Very approachable (In fact, I would give it a 2.5 on difficulty instead of 4). Smooth solve right till the end, thanks!
