Jigsaw Sudoku ( also called Squiggly Sudoku or Odd Sudoku ) is just like a regular Sudoku puzzle , except that instead of the lines being perfect , they are different . A three-dimensional Sudoku puzzle was invented by Dion Church and published in the Daily Telegraph in May 2005 . There is a Sudoku version of the Rubik 's Cube named Sudoku Cube .
