Clifford A Pickover · 2001
Abstract An interesting example of cultural contamination occurred in a secluded West African valley when Dr. Googol left behind a mathematical puzzle called IQ-Block (manufactured by Hercules, designated as Item No. P991A, UK Registered No. 2013287, and made in Hong Kong). The puzzle, schematically illustrated in Figure 20.1, consists of 10 brightly colored polygonal pieces of plastic. The 10 pieces fit together to form a square. Only 1 piece is shaped like a rectangle. The others are more complex. One is shaped like a Z The remainder are Y-shaped. To play IQ-Block, first choose a shape you like, place it in the upper left, and do not change its position as you try to place the other 9 blocks into the remaining space on the square playing board. The manufacturer boasts, “There are more than 60 different kinds of arrangements” of pieces that will fill in the square playing board. The company also states, “It is an incredible game. Join us in challenging your IQ.”
