Sudoku is played on a 9 x 9 space grid. In the rows and columns are 9 "squares" (making 3 x 3 spaces). Each row, column, and square (each cell has 9 blanks) needs to be filled with numbers 1-9. And Shapes Sudoku is designed with many different levels for you to choose from.
Fill in each small square so that: each row, each column, and each square (3 x 3 small squares) contain the numbers 1 to 9
