If you're hosting a bridal shower, there are literally hundreds of games to choose from. Some are silly, some are serious, but all are about having some fun with the bride before she's married. Here's a sampling.
One fun game really puts the bride on the spot with regard to her knowledge of her husband-to-be's life. Prior to the party, have someone ask the groom a series of questions, such as where he was born, what his favorite food is, things like that. Then at the bridal shower, put the bride on the spot by asking her the answers to the questions. See how many she can get right (hopefully at least half!). If she does well, give the girl a prize; she deserves one.
