There’s generally two types: The ones where’s the only one true solution (as in you have to make almost every choice given to you correctly) and ones where there’s multiple solutions (generally you have to get a certain amount of something to win and there’s numerous ways of getting it). In a more meta sense some books are harder to cheat because the dickhead author puts a number on the McGuffin that you have to write down and then turn to the corresponding chapter when you need to use it. Rather than “If you have the crystal of not dying turn to 167, if you don’t turn to 5”.
All of them have “Oh you turned left, that means you die to a werebadger then” style choices in them, though.
