WEATHER GAME
From the Celebration of Light in Vancouver to jazz festivals in Istanbul — each question takes you to a real destination with real weather. Discover festivals, landmarks, and hidden gems from around the world. You might just find your next trip.

KITCHEN GAME
Stuffed Quahogs, Argentinian Provoleta, British Yorkshire Pudding — discover dishes from around the world while you play. Over 200 global and regional recipes turn every round into a cooking adventure.
