'''Basic Trope''': A situation where VideoGame designers ''deliberately'' include a way or ways to make the game {{Unwinnable}}.
* '''Straight''': [[AliceandBob Alice]] has to find the legendary gear of the [[RetiredBadass great hero]] Sir Bob. It's possible for her to miss collecting the [[PowerCrystal Pendant of Power]] or [[GlovedFistofDoom Gauntlets of Greatness]] before the areas where they are hidden are destroyed by [[BigBad Emperor Evulz]]. If this occurs, the game is rendered unwinnable.
* '''Exaggerated''':
** Alice is supposed to gather four other [[ChosenOne Chosen Ones]] and all of [[MacGuffin the legendary equipment]] in order to face Emperor Evulz. It is entirely possible to miss recruiting Princess Carol or Francis, or to destroy a LoadBearingBoss without realizing that one of the legendary treasures is still hidden deep inside the dungeon you just wiped out. The player can't continue from this.
** [[TrialAndErrorGameplay Virtually every action you take in the game can cause an unwinnable state if you do it incorrectly or in the wrong order.]]
* '''Downplayed''':
** Missing an item makes a whole side-quest unwinnable, but not the main plot.
** [[YouLoseAtZeroTrust Angering Francis into leaving]] locks you into the [[EarnYourBadEnding bad ending]] where [[SuddenDownerEnding Alice dies]] after defeating Emperor Evulz.
* '''Justified''':
** The game is one of [[WidgetSeries those weird ones]] where the point of the game is to deliberately avoid the unwinnable game state.
** [[SignatureStyle It's a Sierra game]]
* '''Inverted''': Winning the game is inevitable.
* '''Subverted''':
** When a plot item is destroyed, it appears somewhere else.
** You can miss the Ultimate {{Mon}}. They're the effect, not the cause.
* '''Double Subverted''':
** ...except for one.
** They're the cause of something else.
* '''Parodied''':
** Charlie is playing ''[[ShowWithinAShow Bob's Quest]]'', and his first mission is for Bob to deliver Alice's lunch. He has Bob ''eat'' her lunch instead, rendering the game Unwinnable.
** Alternately, the game has an "Impossible" difficulty setting...which is ExactlyWhatItSaysOnTheTin, as described in the main article.
* '''Zig Zagged''': Alice is told flat-out that she needs to recruit the other [[ChosenOne Chosen Ones]] and is warned that the legendary equipment is well-hidden and may be "[[PermanentlyMissableContent lost forrever to the sands of time]]" if she isn't careful. It's also impossible to miss recruiting Charlie or Belle, and several warnings are given whenever the player is about to potentially bypass a vital item. On the other hand, Carol is difficult to read and doesn't officially join until late-game, and [[BecauseYouWereNicetoMe only if treated well]], while Francis can be {{Killed Off for Real}} without the player realizing Alice can rescue and recruit him, and other equipment can be accidentally missed.
* '''Averted''': There is no way for the player to accidentally miss something important and make the game impossible for them to win.
* '''Enforced''': The designers want players to pay more attention to the world they've created, so they make it that a player who isn't paying attention will stumble into one of these traps and screw themselves over without realizing it.
* '''Lampshaded''': The game in a bit of niceness, causes the save points to refuse to save for you after a MacGuffin is destroyed, stating "You cannot win, assisting you now would be cruel."
* '''Invoked''': Emperor Evulz is deliberately hiding some of the legendary equipment in dungeons with {{Load Bearing Boss}}es so that Alice might accidentally make it impossible for him to retrieve, [[ScrewDestiny making the prophecy impossible to fulfill]].
* '''Exploited''': Bob torments Alice by forcing her to play the game, knowing she'll find it VERY frustrating.
* '''Defied''':
** The game has entered a known unwinnable state, but some [[GoodBadBugs glitch]] or [[SequenceBreaking trick]] is used to beat the game anyway.
** Alternatively, they made the player able to go back and get what they need.
* '''Discussed''': ???
* '''Conversed''': "It's from Creator/{{Sierra}}, half the fun is finding [[TheManyDeathsofYou new and improved ways to screw up.]]"
* '''Deconstructed''': The game gets panned by critics for its sadistic difficulty, and it suffers a reduction in sales because of it.
* '''Reconstructed''': The game designers are catering to a niche group of gamers that like this sort of thing. Anyone outside of that is a bonus.
* '''Played For Laughs''': You can get a [[NonstandardGameover Non-standard Game Over]] by [[IdiotBall throwing the key into the lava when you and your party are on the path to the Evulz's castle.]] Your party members berate you for being mind-numbingly stupid and leave you in a hilarious cut scene. [[CrowningMomentOfFunny This scene becomes a favorite amongst gamers.]]
* '''Played For Drama''': Making the game unwinnable requires [[MoralEventHorizon sacrificing Alice's little sister Beth to get a sword of invulnerability, otherwise known as]] [[DirtyCoward the Coward's Sword.]] The only thing left to do in the save file is to listen to everyone yell at you in disgust. [[EvenEvilHasStandards Even Evulz is appalled.]]
