Ghost in the Graveyard
"Ghost in the Graveyard" is bound to get the kids riled up, so play this one earlier in the night. Indoor play in a large space such as a basement is the best option. One child is picked to be the ghost and stands at a designated base. The ghost turns his back and counts from one o'clock up to twelve o'clock, while the other players run and hide. When the ghost spots a player, he runs after her and tries to tag her. If she reaches home base, she is safe. If she gets tagged, she becomes the next ghost.
Obstacle Course
Kids often bring along sleeping bags to slumber parties. Incorporate these into a game. Have the kids get together to make an obstacle course with objects in the room such as pillows, chairs and couch cushions. When the course is complete, each player takes turns hopping through the obstacles in her sleeping bag. Time each player to determine the winner. Play another round where the kids have to scoot through on the ground in sleeping bags.
Object Hunt
Get the lights out by having a glow-in-the dark object hunt. Throughout several rooms of the house, hide glow-in-the-dark objects such as stars or colored glow sticks. Give each player a bag and a flashlight and turn out the lights. Players then race around to try to gather as many of the objects as they can find. Let the winner choose several of the items to take home as a prize.
Name that Tune
A game of "Name that Tune" can be played while the kids are in bed. Beforehand, compile a list of songs on an mp3 player or group of CDs. Put some obvious ones in the list as well as hard ones. Play a part of each song and have the players guess the song. Award bonus points if the player also can name the artist.
