Capture the Flag
An outdoors game, Capture the Flag is perfect if your party space includes a big yard with plenty of trees and bushes to hide behind. To begin the game, divide the players into two equally numbered teams. Then, give each team their own side of the yard, which you can refer to as their base. Each team's base should house a flag. The purpose of each team is to steal the flag from the other team's base and make it back to their base with the flag in hand. The players all have to attempt to make it to the enemy base, and if a player is tagged by an enemy, he must wait at the enemy base until a teammate tags him, in which case, he's back in the game. The first team to capture the flag wins the game.
Egg and Spoon Race
If you have plenty of eggs about to expire, you can play this simple game perfect for any age group. Divide the players into at least two teams (with equal amounts of kids and grown-ups in each), and give each team one egg and one spoon. Then, line each team up behind a starting point. On the count of three, the first player in each line has to balance the egg on the spoon and race to a finish line ahead of her, and then circle back around to return to the starting point. She then must hand the spoon with egg intact to the next player in his team's line, who has to perform the same task. If a player drops his egg during the race, she must pick it up or get another egg, and start over from the starting point again. The first team to complete the race wins the game.
Family Lineup
For a family reunion, this game is perfect to play with both adults and kids. The party members all must divide themselves into at least two teams, with one person acting as the leader of the whole game. Once you've determined the teams, the leader must present all of the teams with a command. For instance, one command is to line up according to birth date, from youngest to oldest; another is to line up according to height. Each team must attempt to line up according to the command faster than the other teams. When a team believes they have lined up correctly, they shout out "In line!" The leader then goes through the line to make sure the team has lined up correctly; if so, they win a point. If not, they must try again to line up. After a few rounds of different commands, the team with the most points wins the game.
