A Gambit Pileup involves two or more people with completely separate agendas each hatching complicated plans. The storyline is thrown into chaos and even the most savvy fans can't predict how it will all end. Be prepared to make a flow diagram to keep up with everyone's scheme.
Often overlaps with Flock of Wolves or Right Hand vs. Left Hand, and can often be the result of The Big Bad Shuffle. Xanatos Speed Chess is a defining trait. A Psychological Thriller is more likely to have one of these. Expect lots of I Know You Know I Know. Expect a lot of people to be Out-Gambitted, a lot of Unwitting Pawns, a lot of saying "All According to Plan!", and maybe someone to have the Last Plan Standing. Compare Gambit Roulette, where one person has an improbable plan that would only make sense if he/she is near omniscient. Also compare Multilayer Façade. Done well, it strongly affirms The Villain Makes The Plot. Particularly convoluted and fantastical versions of this trope can dip straight into Mind Screw.

- The Romance of the Three Kingdoms reinterpretation Ravages of Time outdoes just about every other example on this list, with the main characters coming up with incredibly complex, multilayered plans, that often predict each others steps with incredible accuracy, to the point where the characters seem literally psychic. Even the MINOR characters come up with what would normally be seen as competent strategies, but for the more important ones, it gets to the point where you swear that they have to be able to see into the future. You literally have whole arcs where it's completely a back and forth between plans, with one strategist predicting the other strategist predicting him predicting them etc.

- In Judaism, (as well as Christianity and Islam which inherited the moral and theological traditions of Judaism), the God Yahweh always comes out ahead in any Gambit Pileup every single time. Thats because rather than making a single absolute plan, He's got a single endgoal in mind that He's working toward. Of course no one is going to beat an omnipotent and omniscient opponent.

- In the world of The Magnus Archives, there exist fourteen Entities - incomprehensible eldritch gods that feed off of fear. Each of these Entities has a ritual that, if successfully completed, will manifest it physically into existence (effectively ending the world), and a group of devoted followers that are trying to bring about their patron's ritual at any cost. This means that there are fourteen individual gambits going on at any given time, and it's up to the protagonists to try and foil all of them. Or not. Because the Magnus Institute was created to serve the Beholding, one of the Entities, the protagonists are unwittingly helping bring about the Beholding's ritual by disrupting the other gods' rituals. This culminates in Jon being compelled to start the Watcher's Crown at the end of season 4.

- Fate/stay night features the gambits of Zouken Matou, Kirei Kotomine, the Einzbern family, Saber, Caster, Gilgamesh, Counter-Guardian EMIYA, and Avenger all being executed during the Fifth Grail War. Slight changes at the start of each route cause different gambits to take precedence in each route.
- Zero Escape is about the plots of various time-travelling psychics- none of which are the viewpoint characters- so things get complicated quickly. Throughout the series:
- Akane's goals are 1), to maintain the time paradox that keeps all versions of her with esper abilities alive, 2), to get revenge on the people who attempted to murder her as a child, 3), to protect the world from global threats such as Radical-6 and Free The Soul, 4), to keep 2 and 3 secret so she can more efficiently achieve them, and 5), to create at least one reality where she gets to live a peaceful, simple life with her loved ones.
- Delta's goals are 1) to stop the terrorist who will incite nuclear war, 2), to motivate a bunch of people who all hate and distrust him and each other to do 1 for him, and 3), to maintain the time paradox that ensures his birth in certain plot-relevant circumstances. Also, 1 being his real motivation is somewhat debatable as the other characters do not trust his claim of being good-intentioned at all.
- Sigma Sr's goals are 1), to help Akane and Phi achieve theirs, 2) to create his 'children', a sentient A.I and a clone, respectively, 3), to ensure his younger self manifests the esper powers that will be vital to achieving 1, and 4), to warn everyone about the approaching apocalypse.
- Basically everyone else is some degree of pawn- whether they know it or not- just trying to survive, protect their loved ones, and advance their own interests.
- In Danganronpa, especially in the second and third visual novels, trials can end up being much more complex than just following clues to figure out who committed the murder. There are several examples of characters who are not the killer who have their own reasons for manipulating the direction of conversation, so multiple characters' plans (including your own) can pile up, leading to several different twists in a single case.
