Hopscotch was published in 1963 and is the account of the life of Horacio Oliveira, an Argentinian man living in Paris in the 1950s. This novel is split into three groups of chapters. Chapters 1-36 are titled "From the Other Side", chapters 37-56 are called "From this Side", and the last 99 of the total 155 chapters are called the "Expendable chapters". 

 

The author includes a "Table of Instructions", but there are multiple endings for the reader to "arrive at by choosing how you’d like to read the novel." (Baron, 2021) The "Expendable chapters" are considered useful riddles and puzzles to help the reader figure out more details and clues about chapters 1-56.
