Survivor Party Games, It's a Team Thing
Survivor is very popular for testing the bonds of a team. In these survivor party games, teams will work together to accomplish a task.
The first game has each team cooperating to keep a ball in the air and off the ground. Have each member of the team grab an edge of a towel or blanket. Place a beach ball in the middle. After "Ready, Set, Go!" Each team will bump their ball into the air by lifting the blanket quickly on their edge. The goal of the game is to get as many "bumps" as possible in the time given without letting the ball touch the ground. This means you really have to work together!
Another fun survivor party game that challenges the mind is called "Stranded on an Island .." Players sit in a circle with the party person going first. They will say "If I were stranded on an island, I would hope to have …." and then name something that begins with "A" that would be helpful to have on an island. (An ax, for example.) The next person in line repeats the full line, the word beginning with "A," and a new word beginning with "B." Play continues around the circle until someone can not remember one of the words. They are out of the circle and play continues, skipping them. The survivor of this game is the last one in the circle.
Stick with the Survivor party theme throughout the event. Hand out buffs for party favors. DVD of the show Survivor are great for game prizes.
