Chess–sudoku hybrids are fairly common, though perhaps not often to this extent. The puzzle is not overly difficult and does not require deep chess knowledge, but a basic understanding of the game is necessary; how the pieces move, what checkmate is, and how a game is won.

For more experienced players, there is a particularly pleasing chess puzzle waiting after the grid is complete.

Rules:

Normal 8×8 sudoku rules apply. Each circled cell represents a chess piece on the corresponding square of a chessboard, with White moving up the board. Each piece type and colour is assigned a unique digit (for example, all white pawns share one digit and all black pawns another), and not all piece types must appear. All white pieces are lower digits than all black pieces, and within each colour the digit values follow standard chess hierarchy if they exist: Pawn < Knight < Bishop < Rook < Queen < King.

The chess position is legal, no piece is currently attacking any piece of the opposite colour regardless of if it is defended, and White and Black have identical material (the same number of each piece type). No pawn promotions have occurred. It is White to move, and White has a checkmate in one.

Digits separated by a white kropki dot are consecutive.
