About Chedoku
Chedoku mixes chess, sudoku and minesweeper into one logic puzzle. Some squares on the board show a number. Move the pieces on the board until the number of threats on each of these squares matches its number. You do not need to know chess openings. You can move each piece to any square.
The creator of Chedoku likes chess and logic puzzles. Chedoku started as a way to put the two together. We add new puzzles regularly. Chedoku has 20 difficulty levels and a new daily puzzle each day. All players get the same daily puzzle.
You can play Chedoku free in your web browser, or get the app for Android and iOS. To learn how to play, read the rules.
