It's About the Numbers! Players in Math Fluxx use positive integers (whole numbers) in their quest to achieve a very mathematical Goal. But, it's not just putting 4 and 2 together to achieve the 42 Goal (for example); Math Fluxx also features the Plan B Meta Rule, which puts Special Victory Rules into play that give you a second way to win and require even more arithmetical acumen. With Math Fluxx, the fun is exponential!
