Twistaplot is a series of children's gamebooks that were published by Scholastic from 1982 to 1985. Books #1, #4, #9, and #14 were written by R.L. Stine, who would go on to write the Fear Street series and the Goosebumps series, which in turn spawned the gamebook spin-off series Give Yourself Goosebumps. The remaining books were written by various authors including Louise Munro Foley. They were Scholastic's response to the Choose Your Own Adventure series. After the success of the Goosebumps series, the Twistaplot titles that were written by R. L. Stine were reissued with new covers in 1994 and 1995.
Twistaplot covers a wide variety of genres, including science fiction, fantasy, and horror. Similar to the Give Yourself Goosebumps series, they are novels with branching plots. The books are written from the second-person perspective, in present-tense form. The protagonist in each book is never referred to by name, and the protagonist's gender is usually ambiguous. Thus readers can easily imagine themselves as the protagonist of the story. Unlike the Give Yourself Goosebumps series, the books have interior illustrations.
After the success of Twistaplot, the series spawned a series of computer games for Scholastic's electronic magazine, Microzine. It also spawned another gamebook spin-off titled Pick-a-Path, which was intended for a younger audience.
