They were of the style commonly referred to as "Choose Your Own Adventure," written in the second person and with branching narratives, with each page ending with two or more options with instructions to advise the reader as to which page to go to depending on their choice. For example: "To go right, go to page 56. To go left, go to page 77."
Decide Your Destiny follows a number of Doctor Who-related gamebooks in this genre dating back to the mid-1980s.
Originally featuring the Tenth Doctor, the books continued into 2010 with the release of editions featuring the Eleventh Doctor. Unlike previous Decide your Destiny titles, all four 2010 books appear to feature the return of a monster or alien that had previously appeared in the television series, the Macra, Sycorax, Judoon and "Werewolves" respectively. They also featured links to exclusive online content.
