Back when I was (much) younger and my friends were getting married, we'd usually have a game of Bridal Bingo.
Another game, for various occasions, was "What's in The Bag?" You put assorted objects into a paper bag and pass it around. Each person has a certain amount of time, to feel the objects (without looking). AFTER the bag is passed, the person starts making his/her list of what was in the bag. Some of the objects should be easy to identify and at least a few should be hard to identify. Examples - bobby pin, rubber band, spoon, bottle cap, piece of plastic, piece of fabric, twist-tie, cotton ball, piece of yarn, straw, etc. The winner is whomever remembers and identifies the most items, correctly. The more items you include, the better.
