** In the second book, ''Fire on the Water'', you come across a fork in the road. [[MortonsFork Both paths]] result in an inescapable ambush by a Helghast[[note]]an undead monster that's invincible to mundane weapons[[/note]]. To get through this encounter, you need to have either chosen a specific ability at character creation[[note]]Animal Kinship[[/note]] or taken a particular path a while back to acquire a weapon that can harm it.

* ''Literature/FightingFantasy''
** ''Literature/HouseOfHell'', by the British Steve Jackson, is virtually impossible to complete without reverse-engineering the entire book, as the path to victory is so obscure and the book so unforgiving (taking one step off the correct path renders the whole thing UnwinnableByDesign).
** ''Literature/CreatureOfHavoc'' (also by the British Jackson) is well-known as being just about the hardest book to complete in the entire series:
*** The player character starts the game not in control of their own actions, with what they do determined by dice rolls, making it easy to miss vital information and items.
*** The character also starts off ''not understanding human speech'', thanks to an extremely clever mechanic where all in-game spoken and written English is in code.
*** The only true path through the game includes a section that [[spoiler:ends in your character's death. You then need to use an inventory item to TakeAThirdOption which is not given by the text, which some people might not think of even if they have the item in question.]]
** ''Literature/BlackVeinProphecy'', which has an instance where the player has to '''fail''' a stat check in order to get an item required to complete the book.
* The ''Literature/GrailQuest'' book ''Tomb of Nightmares'', due to its complex secret door system which makes it very hard to find the correct way through the labyrinth in the titular tomb.
* ''Literature/LoneWolf''
