Teens enjoy sleepovers as much as younger kids, but most slumber party games require a more mature twist. Teen girls like games that involve social interactions, whereas teen boys typically enjoy active play. However, a variety of games are suitable for both genders. The goal is to encourage a fun, friendly atmosphere and a way for teens to bond with their friends. Reward the winning team with a prize, such as a bottle of fingernail polish for each girl, an inexpensive pair of ear buds for each boy or gift certificates for downloadable music for either gender.
Truth or Dare Balloons
Add a twist to the classic kids' game "Truth or Dare." Write a question-and-dare set on a small card, and place the cards in individual balloons. Each person pops a balloon when its her turn and decides whether she wants to answer the question or perform the dare. This version of the game allows you control over the topics for discussion -- and the dares -- so teens don't ruin their reputations or get in harm's way. For example, you might write on one of the balloon cards, "Truth: What movie star would you most like to date? Dare: Mix liquid ingredients from the refrigerator, and take a sip of the concoction."
Pajama Soft-Foam Ball Wars
Organize a game of soft-foam-ball wars to play in a large basement, living room or backyard -- as long as your neighbors don't mind the noise -- once everyone changes into their pajamas. Use soft-foam firing toy weapons or select a variety of foam balls that slumber party attendees can throw. Divide the participants into two teams so they can create a team strategy -- the goal is to hit every player on the other team with a foam ball before they hit your players.
If you don't have access to foam balls, play the game in the dark with flashlights -- the goal is to aim your flashlight directly at an opponent to count it as a hit.
Capture the Flag
Add a competitive edge to outdoor, nighttime fun for older teens, such as playing a classic game of Capture the Flag in pajamas. Divide your backyard in half or use your house as the dividing line between your front and back yards. Assign each team their own yard space -- known as their zone -- to hide their flag. You can use any two items that are similar in size, such as stuffed animals, if you don't have flags. Give each player a flashlight. The goal is to find the other team's flag and take it to your area before they find and capture your flag. To avoid kids tackling one another to protect their flag, add a rule that players must return to their zone for 20 seconds if they're tagged by an opposing player in the opponent's zone. No tackling, tripping, pushing or pulling allowed. Make sure your yard is free of furniture, lawn sprinklers, stakes, recreational equipment and other things so slumber party guests don't trip and fall in the dark.
Create a scavenger hunt that revolves around teen-related items, such as personal hygiene and beauty products, kitchen utensils, sports equipment, collectibles -- just the nonbreakable ones -- earbuds and other digital accessories. Start the game once everyone is in their pajamas, and restrict the game to your property. Divide the group into pairs or small groups to encourage teamwork. Prevent your own teen from having an unfair advantage by hiding items in places that she won't think to look. For example, you might hide a roll of toilet paper in an empty, kitchen canister.
Scary movies are a staple at many sleepovers, so with that thought in mind, offer a spine-chilling game. Have one sleepover participant hide in the house, garage, outdoor shed or backyard. Ensure the one hiding has a cell phone with the host's home phone number on it. Turn off all the lights. Every two minutes, the hider must call the house line and give a clue as to where she's hiding. The phone must be on "speaker phone" so all the players can hear the clue. If all of the participants have cell phones, the hider could send a group text message rather than calling the home phone. This works well if other family members are sleeping, and a ringing phone is too noisy. Have the teens take turns hiding.
