We have three older kids and have had a party every year. The last 5 years they have been for kids ages 10-15 and we do have organized games. I've listed a few of our favorites over the years.
Most Monstrous Makeover: The players can be divided into groups of two, three or four players. A bag of assorted items such as false eyelashes, makeup boxes, lipstick, false noses, wigs, and so on should be given to each team. Each team will choose a member of their team to make up. Each team should be given about 5-10 minutes to turn the person they are making over into a monstrous looking creature.
Bobbing for Donuts - tie powder sugar donuts with a string and hang 3-4 on a broomstick. Hold the broomstick and donuts over the kids heads - with there hand behind their backs (they can be blindfolded too) they have a race to see who can eat the donut off the string the fastest.
Mummy Wrap -- it's an old time favorite even with the big kids. You can get creative and have them race to wrap their mummy inb toilet paper but you can also have them "design" the most fashionable and creepiest. I had some supplies like boas, sunglasses, hats, old costumes and such that they adorned their mummies with after they were wrapped.
Bone Hunt -- Have the kids search for skeleton bones using clues and have them race to see who can build their skeleton first. We took three plastic Blucky skeletons and spray painted them with different colored GLOW in the Dark spray paint - one color for each team. We painted them on a black sheet so we had the skelton outline for the hunt. Then we took apart the bones and wrote clues on each bone as to the next bones location.
Dance Games -- Monster Freeze Game - when the music stops freeze in your scariest pose.
Decorate pumpkins -- break out the paints, glitter, gems, toile, plastic spiders, and fabric - anything you can think of to decorate a pumpkin. They don't need to paint faces on them if they don't want to I just encouraged them to decorate the pumkin and they went all out.
Dreadful Doodles - a relay race of drawing Halloween themed words. Divide up in teams. The doodler for each team runs to get a word from a Halloween container and runs back a draws it for their team when the team guesses the next doodler runs to get a word - they continue the race until each person on the team has been the doodler and all of the words were guessed correctly.
Ghost stories -- Everyone sits in a circle and someone begins the ghost story each person than adds to the story (there are lots of twists that can be added to this game)
Play the Murder (wink game) --
Zombie Tag
One year we had a Fear Factor Theme - if you are interested I can give the games we played for that.
We've also done a murder mystery party.
This year we are having a scavenger hunt and fortune telling/tempt your fate activities. We are using the Martha Stewart fortune cookies and filling them with dares and rewards.
