As with the other puzzles, I would highly recommend you print them, cut out the images, trim up the board, and laminate them all, for more prolonged use! Before laminating it, you can put the puzzle board on a piece of colored construction paper or scrapbooking paper, and glue the answer key on the back so you don't lose it!
original Sudoku Puzzles I created for you on my computer, but these Halloween images were tailor made and are so fun (and so not scary! my girls don't draw scary - I even had to draw the skull! lol!)
If you print off the Level 3, you'll have to print off the 4th page (with the answer key) to have the remaining pieces for the game too.
