If They're Planning a Sleepover, Try These Ideas to Keep Them Entertained All Night Long
1) Create a Scavenger Hunt

Scavenger hunts are endlessly versatile, and you can tailor them to the age, interests, and competitiveness of the crowd you're hosting. Kids can work together in a cooperative challenge, or race to see who can complete their hunt first to win a prize.
4) Play Lawn Games

We're living in a Golden Age of lawn games, and the choices have never been more vast. Whether they're looking for a classic came like croquet or kubb, or something newer like Kan Jam or Flickin' Chicken, lawn games will get them outside, active, and tired out (so they might actually sleep).
7) Test a New Board Game

There are board games out there for every age, from simple, cooperative games that encourage teamwork to casual party games that inspire a lot of laughs to sophisticated games with complicated rules that tests their sense of strategy. They can open a new game — or even a few! — and learn the rules together.
25) Pillow Fight!

Set some ground rules first — no hitting in the face! — then let them go crazy. Maybe hide your best pillows, too.
28) Or Play Spin the Bottle — of Nail Polish

To add an element of chance into a manicure night, gather the kids in a circle and grab a bunch of nail polish colors. Select a polish bottle, spin it in the middle, and whoever it points to has to paint one nail that color. Continue until all the nails are painted.
29) Or Skip the Nails and Do a Face Mask

Because no photo is more hilarious than a bunch of young ones with beauty cream all over their faces.
30) Play 'Murder in the Dark'

Pull cards out of the deck so that there is enough to give one to each player; they all should be numbered cards, except for one ace and one face card. Deal them out: The ace becomes the detective — the only person who reveals their card — the face card is the killer, and everyone else is a potential victim. The killer then proceeds to take victims by winking at them when no one is looking, and it's up to the detective to guess who the killer is before everyone has succumbed.
33) Play 'Celebrity'

It's Charades with a twist: Everyone writes down the name of a celebrity (real, fictional, or historical) and puts it in a bowl. In the first round, players can say anything but the celebrity's name to get their teammates to guess who's on the paper. For the second round, the same names go back in the bowl, but this time players can only use one word before the team guesses. The last round, the same names go in again, and no words are allowed — players have to act it out like charades. The better kids get at it, the more names you can put in the bowl.
36) Dance Contest!

Or, if you balk at the competitiveness of an individual dance contest, you can have them split into two teams and work together to choreograph a group routine. Send a video of their hard work home with them.
37) Go Watch the Sunrise

Cross your fingers that the kids got at least a little bit of sleep beforehand. But, if you hear giggling in the early-morning hours, you can herd everyone to a good sunrise spot.
38) Pancake Brunch

Everyone can talk about all the fun they had the night before while whipping up a batch of super-easy pancakes. Whipped cream and fruit toppings are optional.
