How do choose your own adventure books work?

Choose your own adventure books work by ending each short section with a decision that sends you to a different page, so the story branches based on what you pick. Instead of reading straight through, you might finish a section and choose to open the door (turn to page 40) or walk away (turn to page 8), and the paths split from there. Some branches loop back together, some dead-end, and several lead to different endings. The writer maps this as a tree or web of numbered sections before writing a word, because the structure is the hard part. Digital versions replace page-flipping with clickable links, which makes longer, more tangled branch maps practical. If you want to build one, the Visual Builder lays the branches out as a node graph.
