Chedoku: A Chess Puzzle with Sudoku Logic

Chedoku is a free logic puzzle on a chess board. It mixes chess, sudoku and minesweeper into one puzzle.

How to play

Some squares on the board show a large number. This number tells how many pieces must threaten that square. Move the pieces on the board until each square has the correct number of threats. A white piece adds one threat. A black piece removes one threat. You do not have to obey the rules of chess when you move a piece.
