To complete the puzzle and impress King Roo with your numerical skills, fill in all the blank squares on the gameboard with the correct numbers. Choose the number that should go in each square by moving your mouse over the square and clicking when you see the number you want to place.

There are three important things to keep in mind when playing Roodoku.

• First, every row of numbers must include the digits 1 through 9.
• Second, every column must contain the numbers 1 through 9.
• Finally, every 3 x 3 square within the larger Roodoku board must also include the digits 1 through 9
