Here is some games that i have came across.. thought they could be helpful.
Pass The Box
This is really fun, Take a small gift or toy that all kids would enjoy, then gift wrap it, but keep wrapping it with different layers of giftwrap. Play some music while passing the present around, when the music stops, the guest left holding it unwraps the first layer of wrapping paper, then the music starts again and the box is passed, then every time the music stops, another layer is removed until someone finally unwraps the very last layer,,,,, and that is the winner. It is kind of like Hot Potato, but this is an item that everyone wants to hold on to!
Bubble Gum Game
This game can be played as a relay race or be based on individual times. Split your guests into teams of 3-5 people. Get some paper plates, bubble gum, and whipped cream (in a can). Put a piece of bubble gum on the plate and swirl the whipped cream over it until the bubble gum is completely covered. Then have your guests dig through the whipped cream and find the bubble gum. Here's the catch, players must keep their hands behind their backs and dig through the whipped cream with their faces! Once they find it, they must chew it and blow a fairly good sized bubble. Go through until every one has had a turn. The person who blows the bubble first is the winner. You can also do several rounds until you have one winner. *Depending on what your guests wear, you may want to have a towel or garbage bag to use as a bib.
Sleepover Game - Stuffed Animal Find
Have all the people that are coming to the sleep over bring a stuffed animal. Once they arrive, take their stuffed animal and place it in a pile, you could also use a large box, with the other stuffed animals. Then during the party, gather your guests and blindfold one and have them search through the pile to find their stuffed animal using only their hands. Everyone that finds their's gets a small prize.
or even do simple stuff like BINGO and just have a few cheap prizes for the person who gets bingo.
maybe a scavenger hunt would be fun.
you can do a few cool games maybe before everything starts take your daughter the movie rental place to pick out a movie for them to watch after all the excitement is over so they can get relaxed for bed.. i know if i was 9 again i would have a blast with these games... good luck and hope this helps you ....
