Big Brain Academy is the most-played Wii game in our house. The puzzles are challenging, and get harder as you succeed, meaning that everyone from my kindergartner through his grandparents can have a fun challenge. The puzzles vary widely; some test memory, others listening skills, others visual acuity, yet others spatial acuity. Party mode allows the whole family to compete against in each other. This is a terrific game, and I highly recommend it. Note: As expensive as Wii games are, I like to rent them first to try them out before plunking down $50 for them. Know that your "brain size" will stay on your Wii, so if you do buy after renting, it's like picking up where you left off with the rental. Good stuff!
