Hopscotch is a stream-of-consciousness novel which can be read according to two different sequences of chapters. This novel is often referred to as a counter-novel, as it was by Cortázar himself.
An author’s note suggests that the book would best be read in one of two possible ways, either progressively from chapters 1 to 56 or by “hopscotching” through the entire set of 155 chapters according to a “Table of Instructions” designated by the author.
Cortázar also leaves the reader the option of choosing a unique path through the narrative.
