Get into teams of 2-3 kids. Using toilet paper, wrap one of the team members as fast as you can! Then the "mummy" needs to run (or hop!) to the finish line to win.

Halloween Can Toss
This traditional carnival "knock 'em down" game is an oldie but goodie. If you want to make it a little more challenging, add a bit of weight to the cans, so the cans aren't so easy to knock down. I would also recommend using soft bean bags (instead of a hard ball) so you don't risk damaging the back wall. Better Homes & Gardens makes it easy to make this fun game with cute free downloadable printables here.
I'm using this one for our Halloween party. Use templates (MarthaStewart.com is a good source for templates) to cut out some creepy "ingredients" for a witch's brew: bat, fly, mouse, bones, etc. Place the shapes beside a bowl/cauldron. Using a straw as a "vacuum," each child tries to pick up a shape and place it in the bowl to create the Witch's Stew. You can either time the players to see who can get all the shapes in the bowl the fastest, or set a goal for a prize, "Put five in to get a prize." Photo source here.
Doughnuts on a String
Here's a great alternative to "bobbin' for apples." Have kids and adults race to finish eating a doughnut from a string without using their hands! Use frosted orange doughnuts that are often seen in stores around this time. For complete game directions, visit MarthaStewart.com here.
