Sudoku is a number-placing puzzle based on a 9 x 9 grid with several given numbers.
The object is to place the numbers 1 to 9 in the empty squares so that each row, each column and each 3 x 3 box contains each number only once.
There are five Sudoku Puzzles one for each day of the week. Ask reps to sign and return their completed Sudokus. Reward everyone who completes each puzzle with a small prize and enter them in a grand prize drawing.
