The crossword feature of a Crossoku puzzle provides an extra element of fun and help to doing a traditional Sudoku puzzle. Without altering the basic play of Sudoku, “fitting” the crossword answers into the Sudoku grid is a way to accelerate your completion of the puzzle. Instead of solving the Sudoku one number at a time you place several numbers together (the crossword answer). Number values are assigned to the letters in the answer. All Sudoku rules must be complied with when placing the crossword answers.
