When the rain is drumming against the windows and outdoor plans are cancelled, the atmosphere can quickly turn from cozy to cabin-feverish. A rainy day doesn’t have to mean mindless screen time, though. It’s the perfect opportunity to gather friends or family for a structured, engaging, and mentally stimulating challenge.
