I'm actually planning games for a chicken BBQ for next weekend. Here's a few ideas.
Pass the sand-take handfulls of sand from one side of the yard and race to the other side and fill a bucket that was premarked. First to fill to the mark, wins.
Presents- 2 people have one rt hand tied to the others lt hand. Then they try to wrap a present with a bow. 1st to finish, wins.
Feed a friend- standing back to back, one person has a pole with a string and on the string is a candy bar, that person tries to feed the other, with being back to back, and the other has hands tied.
Balloon on the ankle-tie a baloon to everyones lt leg. Try to pop the other people's ballon with your rt. Last balloon wins.
Kangaroo- ballon between the legs and race to the finish line.
Egg on a spoon- so many eggs to a bucket at other side of yard, balancing the egg on the spoon. If you drop it, back to the beginning.
Water balloon toss or egg toss.
Scavenger hunt-you can get many ideas for that on the internet.
These are just a few. I googled party games and found a ton. Most of mine are for outside and a range of ages. We are also having a 3 legged race, pie eating contest, leap frog (1 adult to 1 kid)And many more. Maybe some of these will help you make your own games and ideas. Good luck.
