Steinbeck is often described by critics as a believer in a "non-teleological world." This is a world where chance plays a major role. It is chance, for instance, that Slim happens to be in the barn when Curley comes into the bunkhouse looking for his wife. It is also chance that George is absent from the barn when Lennie is burying his pup and Curley's wife comes in. Steinbeck tries to show that man cannot understand everything that happens, nor can he control the world around him. For this reason, events often appear to be random.
George's Solitaire game in the bunkhouse is exactly that. It symbolizes the random appearance of events just as cards are drawn out at random from the deck. All is a matter of chance in Solitaire, and the same is true of the events in the book that Steinbeck thought about titling "Something That Happened." The isolation of the ranch and the interplay of personalities in the bunkhouse also contribute to the idea of chance. The world is unpredictable, and in this setting, plans often "go awry."
