Braggart is a light card game by Kyle Daniel, published by Spiral Galaxy Games.
It looks like a story-telling party game, but it’s not. You try to collect and meld the parts of a ridiculous story; the most outrageous story wins. You can play Lie cards on each other to swap out big boasts for little one, to reduce a story’s total value.
I said it’s not a story-telling game, but it looks like you’d have a hard time not laughing and getting into the theme as you play each ridiculous story down on the table.
