Mingling Games
Tape an index card to each person's forehead with the name of a famous personality written on it, facing outward. The person wearing the card should not know whose name is written on his forehead. Have each person walk around asking yes or no questions about who is written on the card until she figures out who she is meant to be. Questions like "Am I female?" and "Am I a movie star?" are appropriate questions. Alternatively, hand participants the wrong name tags as they arrive. Individuals must then introduce themselves to each other in order to find the correct owners of the tags as well as their own name tags.
52 Card Shuffle
If you have a large group, play the 52 card shuffle game. Hand out a playing card to each person; if there are more than 52 people, hand out cards from an additional deck. Ask everyone to get together in certain arrangements. Arrangement examples include the same suit, those with the same number or face card, and full house or straight arrangements. Have the groups talk and introduce themselves for a given amount of time before moving on to the next arrangement.
Spoons
Have everyone sit in a circle and set enough spoons in the center that there's one less than the amount of people playing. Deal four cards to each player and have the dealer pick up a card from the deck, look at it and pass it to the person on his right or left. The dealer keeps picking up cards from the deck and passing them in the same direction as the first card. The object of the game is to be the first player with four-of-a-kind. Once you have four-of-a-kind, pick up a spoon. Once you see someone grab a spoon, pick one up because if you don't grab one, you're out of the game. Take out a spoon from the center each time a person is out of the game, so there is one less spoon at the beginning of each round. This will make people get to know each other rather quickly.
Asking Questions
Write several questions along the surface of a large beach ball. Use silly and fun questions like "Was there life on Mars?" or "What do you think a cat conversation would sound like?" Have everyone sit in a circle and toss the beach ball into the air. Every time a person catches it, she must answer the question under her left thumb. Alternatively, write out a series of similar questions onto strips of paper and place them into a paper bag. Have everyone take turns pulling out a strip of paper and answering the question that's on it.
Get-To-Know-You Games
Play games that will help everyone get to know each other a little bit. Pass around a roll of toilet paper and ask each person to tear off some. Then go around the circle again and have each person tell one fact about themselves for every square of toilet paper they have ripped off. Alternatively, ask every person to share two truthful things about themselves and one lie. Direct the group to identify which piece of information is the lie.
