I used to love adventure game books (relics worth a lot on eBay now!), which had numbered paragraphs, where you moved from one to the other by throwing a dice, or by placing transparent cards on the book which would reveal which paragraph to go to next. There were some Famous Five ones, which were frustrating because if they ran out of provisions for their lunch boxes, the game was over, and you had to start again. This could happen if Dick tripped and broke his bottle of ginger beer, or if Anne fed some cucumber from her sandwiches to a tame rabbit. I loved programming in Basic, and I wrote programs of these. The computer I had didn't have enough memory for the complete text (which I would have typed out), so I wrote shorthand versions, and even did a few diagrams.
There was a brilliant one called "Suspects!" which was set on the "Olympic Express", clearly based on a famous train with a similar name, where you were the detective trying to find out which member of a film team had murdered the unpopular director; it would be a random murderer every time you played the game. That book needed some skill: you had to study a picture, then turn to a different page to answer a question on it. If you got it right, you got a clue to the murderer's identity. If you were wrong, the murderer would try to kill you. Some of the ways this could happen were vividly described, and were absurd. "The murderer had smeared oil on the cabin floor for you to slip on, and then pulled the emergency cord to make the train suddenly brake!"
My favourite part of all in that book was when you are watching one of the suspects snacking on a burger at a station stall, and the narrative comments "he seems to enjoy this burger much more than he did the top-class cuisine served on the train! Perhaps he's not used to being a big star yet, and yearns for the life he had before."
