A great game is the 'Candy Bar Story Builder'. The host starts a story about the bride and groom, like 'Once upon a time, there was a bride who was like a KitKat, she had layers of wonderfulness.' Then each guest takes a turn adding to the story using another candy bar as a description. It's a really creative and interactive game.
The 'Candy Bar Character Game' could be fun. You make up a story about the bridal couple's journey, but instead of using their real names, you use the names of different candy bars as characters. For example, the groom could be a Twix and the bride a Milky Way. The guests have to remember the story and then later answer questions about what the different 'candy bar characters' did in the story. This is not only entertaining but also a good memory test for the guests.
There's the 'Candy Bar Prophecy Game'. In this game, you tell a story about the future of the bridal couple using candy bars. For example, 'The couple's life will be as rich as a Reese's Peanut Butter Cup because they will always have each other, just like the peanut butter and chocolate.' Then the guests have to come up with their own 'candy bar prophecies' for the couple. It's a positive and light - hearted game that gets everyone involved in thinking about the couple's future.
