How fast can your eyes get a message to your hands? If the answer is, "like lightning," then you just might slay the competition in this speed stacking game. Each player gets a set of colored blocks, and each card has a different block pattern to replicate. The first person who builds the chosen pattern correctly, slaps the card, and screams "Bllox!" wins the round. It's a great way to exercise your brain, work on hand-eye coordination, and make noise for fun. Ages six and up. Made from FSC-certified wood in China.
