Photograph Scavenger Hunt
You can host photograph scavenger hunt games for any holiday that uses outdoor decorations. Holidays where people in your neighborhood regularly decorate their homes are best, as it gives your guests an area close by to search for items on the list. Create a list of holiday decorations and assign points on a one to 20 scale based on how difficult you think they will be to find. Split your guests into teams of three to four each, and give each team a digital camera to use. Teams are given a time limit to photograph as many items on the list as possible and return before the deadline. The team that photographs the most points wins, ties are settled with the first team in the tie that finished being the winner.
Gift Bump
Choose a theme for the gifts that your guests should bring. For Christmas it might be a specific price range. For Independence Day it might be something using the colors red, white or blue or have a patriotic theme. Halloween could be candy. The gifts should be wrapped. Choose an order for your guests to play the game by picking numbers out of a hat. When it is a player's turn, he can either open a wrapped gift or steal one from someone that already opened one. If a guest has a gift stolen he can then steal as well or open an unwrapped gift. A round ends when an unwrapped gift is opened. You can set limits for the number of times a specific gift can be stolen or how many can be stolen before someone must open a wrapped gift.
Trivia Games
Holiday trivia lists can be created for many of your holiday parties. Holidays like Christmas, Halloween and Independence Day can include questions about the history of the celebration. You can also include questions about holiday specials or movies for each of the different holidays. Prizes can be given based on the the theme of the holiday. A Christmas trivia winner might get a small wrapped gift, while the winner of Halloween trivia might get a small bag of candy, for example.
Target Games
Create a target that is themed for the holiday you are celebrating and have your guests try to throw an object through the target. As an example, for Halloween you could use five pumpkins at different distances from a foul line where contestants throw candy corn. For Independence Day, targets in the shape of stars could be used. Each target will have a different point value based on how far it is from the foul line. Players get points for landing candy or a ball in each target, with the highest scoring player winning a holiday-themed prize.
