Get out 11 makeup items and two dice. Label the makeup from 2-12 get the 1st player to roll the two dice. Whatever number the dice adds up to (eg. 5) you'd put on the makeup labeled 5.

Well since its a pre-teen sleepover you can play maybe a few wii or xbox games, maybe truth or dare, a few board games like monopoly,twister,sorry,and any other board games you can think of,you can also do makeovers. If there's gonna be all girls you can make bracelets or something. If there will be boys and girls than you can play spin the bottle. You can also make a video,take pics,watch movies,pull pranks, gossip,play would you rather,listen to music, or anything else you and your friends can think of if you guys get bored...

Blind makeovers....

Thanks

Play Library make sure that you have some books or a home library and just have one person be the librarian and everybody else be the kids who come to check out the books.

Play a game where 1 person is "dead' and 1 person tells the other all about their 'pretend' life! Its a blast!

Well i think you can play truth or dare.
If its just wit girls u can play call the crush

Wink murder and murder in the dark are the best games to play at a sleep over

Personally,
Considering the fact I am a pre-teen, Makeup and hair is always fun, and sometimes maybe a spa theme with nail polish and mint julep masks.

Write names on a piece of paper and draw a name then write hair nails and make up on a piece of paper(u may need to repeat) then draw for that. You do what u got on ur 2nd piece of paper to the person who's name you drew 1st.

Light as a feather stiff as a board .

Bus station. Have 1 area be the bus station and have 1 "sane" person sit there. Have another person come to the bus station, they're the "insane" one. Have the sane person react to whatever the insane person does (for example the insane person starts to scream randomly the sane person would say something like 'will you stop!' or 'just be QUIET please'). Its a very very funny game.

Sleep!

Well for a sleepover with pre-teens i think you would play truth or dare, because truth or dare is always fun. I always play it at partys and sleepovers. Usually theres people who makeout but thats always fun because you are girlfriends of each other (:

Panic word would be a good game or blindfold makeovers or this game were u have two bowls one with cotton balls and one with nothing u put a blind fold on a person give them a big spoon then they have to get as many cottonballs into the empety bowl in 1 minuet with the blind fold on
