I like the idea of that game! Awesome.
I am definitely in the same boat, I'm hosting my 13 year old sister's Halloween party this year and need some good ideas as well. Our house isn't too big, so there are only going to be about 6 girls there. I'm trying to avoid the electronic games and go for something old-school
Here are some things I've come up with so far:
One idea I found that would be cool is getting a large bowl of cold cooked spaghetti noodles, adding stuff that makes the noodles extra slimy and gross, like a bit of oil. Even fake bugs or fingers and toes. Add plastic eyeballs with a number written on the back. The kids have to put their hand/arm in there and search for an eyeball, and the number on the back indicates which prize they get. (Such as a little basket of goodies, a movie or a giftcard of sorts)
The Wrap The Mummy is always fun. Prize for winning team with the best mummy.
One year a friend of mine did a party game where she dangled donuts off a piece of string in her kitchen, and the idea was to get everyone on their hands and knees and eat their donut first without utilizing their hands or dropping their donut! Messy, but we had a blast! This game is totally on my list. A prize for the one who is able to complete the challenge. I guess if you want to be healthy (as hard as THAT is on Halloween) you could use apples or another fruit/veggie.
Skeleton Scavenger Hunt - A plastic skeleton would probably work best, take him apart and hide the parts in separate sections of your house or the outdoors. Divide the guests into teams and have a race as to which team can find all of the parts and put them back together again. Prize for the winning team.
Pin the Face on the Pumpkin - self-explanatory. You could use an actual pumpkin with black construction paper cut-outs for the face. And of course, a blindfold is needed
It's a good game for girls who like to giggle and laugh at themselves. Prize for the best pumpkin face I assume, haha. To make it even more interesting, you could have all the guests go at the same time, and have to actually glue the cutouts onto the pumpkin, as compared to having tape stuck to the back, and all they have to do is just position and place it on the pumpkin. It's easier to judge who's is the best when they are all lined up. Add in a time limit perhaps?
I'm doing pizza and veggie/fruit trays for food in between games. Maybe add some finger food like chips and skittles (as was suggested before
And I guess to make it all come together, little gift bags at the end of the party filled with whatever. Candies, pencils, jewelry etc.
Hope my entire party plan helps!
