From the publisher: The Game of Great Questions! Kids love to ask questions, and Secret Square encourages great questions. One player secretly hides a chip under a square, then the other players ask questions to remove squares . . . until the only square left is the secret square. Simple enough for a 4 year-old, challenging enough for parents and older children. Great developmental game for young children—it enhances deductive reasoning, set-building, and sequencing skills. 1997 Parent’s Choice Toy Approval Award Winner.
