It's a circle... not a square

Slaughterhouse-five may be said to be written in a circular pattern because Billy keeps jumping around and never stopping. Billy keeps going back to past events and repeating them, like a loop or a circle. "(Billy) fell asleep, and he travveled in time to 1967 again-to the night he was kidnapped by a flying saucer from Tralfamadore"(Vonnegut 90). It states in the quote that Billy traveled back in time. This shows the loop of the story, and the loop of Billy's life. It even states on the next page, when the new chapter starts, "Billy Pilgrim could not sleep on his daughter's wedding night. He was forty-four"(Vonnegut 91). The dates and ages that Vonnegut adds shows exactly where Billy is jumping to. His life is going in circles and we as the audience are just following him.
