"Puzzles bring out important qualities in each of us: concentration, curiosity, a sense of play, the eagerness to discover a solution," comments Erno Rubik in this thoughtful memoir, as he reflects on his lifelong obsession with puzzles, and tells the story of how the cube that he made for his own amusement back in 1974 became one of the bestselling toys of all time. Trained as an architect in his native Hungary, Rubik also makes a case for always being an amateur—something he has always considered himself to be—and stresses here that anyone can be a true creator.
