About ChessDoku

There is a su doku chess variant out there which involves numbers 1-8 and a chess piece. That is not what Chess Doku is! Chess Doku is purely su doku but with chess pieces instead of numbers.

We have three different sized grids (4x4, 6x6 & 9x9) and hundreds of puzzles for you to solve. New puzzles are constantly being created and uploaded.

Successfully complete a puzzle in the fastest time to reach the top of its leader board. Top the most leader boards at the end of a calendar month to win prizes*.

To solve a puzzle each row vertically and horizontally and each box must contain one of each piece.

Click start for the puzzle to begin and the clock to start.

Click a piece on the left side to select it then click on the square you think it should go to place it. If you wish to remove a piece just click it and it will disappear. If you're stuck and need help click the hint button and a random horizontal or vertical line will be filled in for you (one hint per puzzle).

Once you’ve filled all the squares click ‘finished‘. If you have successfully solved the puzzle the timer will stop. In the V.I.P section if you have solved the puzzle in one of the fastest times your name will be added to the leader board.
