One activity for New Year's Eve is a game where guests anonymously write down resolutions on paper and mix them into a basket. Resolutions are read aloud, and guests write down the name of the person they believe wrote it. The guest with the most correct guesses wins a prize.
Another New Year's Eve activity idea is for each guests to tell the group two actual resolutions and one fake resolution. The other guests must guess which is the fake resolution. Another activity is to have guests write down the name of a celebrity or character on a Post-it note or slip of paper. Each guest has one of the names placed on his forehead by the person to his left without showing him the name. Guests may ask yes-or-no questions to figure out the name of the person.
One activity is to create a time capsule of any items or information from the last year into a container that is buried or hidden until some future New Year's Eve. Another idea is to create a scavenger hunt made up of party supplies, such as party hats, streamers, champagne glasses, balloons or noise makers. Alternately, a treasure hunt is another idea where clues are scattered around the party or using party supplies as markers that lead to a treasure.
