For this, you need to carve out a pumpkin with a larger and wider mouth, and place it on the ground. Cut a long, rectangular piece of cardboard to make a ramp, and tape it 2 feet from the ground at the mouth of the pumpkin.
Make sure that the cardboard is stable and well-balanced. Mark a starting point on the ramp, and ask the kids, one by one, to hit a golf ball inside the pumpkin. Give 3 chances each. The one who succeeds, gets a prize.
Arrange a darkened room with only one flashlight in the middle. Now make a circle, and sit around the flashlight. Ask one of the players to start, "Once there was a ...", and let the others continue by taking turns. Each player has to add some crazy, scary, and gross sentences in a flow, and make up their own ghost stories.
Hot Pumpkin Game
Ask the kids to stand in a circle, and pass the plastic pumpkin when the music is on. As soon as the music stops, the player holding the pumpkin has to make a Halloween sound which should be recognized by the other players. Fun preschool Halloween party game, isn't it?
Bobbing Apples or Donuts
Grab some apples/donuts, tie them with a string, and hang them from a tree branch or curtain rod. Ask your kids to snap a bite of these treats while their hands are tied behind with a rope.
Ask all the kids to stand randomly in the backyard. Choose one to take the den, while the rest should stand motionless and still, like expressionless zombies. The player who has taken the den must try to make the zombies laugh, smile, or giggle.
If he succeeds in doing so, he is joined by that person, and the game continues until only one zombie remains. This kid is declared the winner.
Ask the kids to stand in a circle, and give a ball of yarn to a player. He should take a piece of the yarn and throw it to someone else in the circle. This cycle continues until a spider web is created. This will have the kids in a tangled lot, giggling to glory.
Buy some tissue paper rolls. Separate the group of kids into teams consisting of 2 members each, and hand them a roll. One player needs to be a mummy while the other has to make him/her one. The team who finishes first, wins.
Now this Halloween party game is to be played in the backyard, and is very popular among teenagers. It can be played by younger kids as well. Make teams of 4-5, and give each team a capture flag with a ghost theme (pumpkin, spiders, ghosts, etc.).
Hide the capture flags partially in the others territory and ask the team members to find them. However, while doing so, the players shouldn't get caught by the other teams. The team who finds their flag first, wins.
