| Lock and Key Puzzle | comment |
One of the two fundamental Adventure Game puzzle types. This sort of puzzle is based on collecting an item or items from somewhere in the model world, and delivering them to some other place, where they can be of use. The archetype of this puzzle design is an actual physical lock. The player must retrieve the corresponding key from somewhere else in the world, and bring it to the door. Another very common form is a non-player character who performs a task which alters the state of the game world when he is given the proper payment. Another variant uses a combination lock or similar that requires a code, and the player has to determine the right answer from hints in in-game documents. In its simplest form, the player must do nothing more than bring the relevant object to the right place in order to solve the puzzle. Games with a more sophisticated user interface will require that the player use the "key" in some way specific to the nature of the puzzle, though in unskilled hands, this can lead to a Guess The Verb puzzle. The Lock and Key Puzzle is one of the oldest and most common puzzle types across adventure games, especially Interactive Fiction. Its advantages include a tighter coupling with the model world than the Set Piece Puzzle. The setup is also easy to couple with plot developments, using the "key" as a Plot Coupon. The major disadvantages of this puzzle type are, on one hand, the possibility of Combinatorial Explosion and, on the other hand, the possibility of This Looks Like a Job for Aquaman. See also Broken Bridge. If the "key" is something non-intuitive or ridiculous, you've got to Solve the Soup Cans. For examples that are literal locked doors that require a key, see the subtrope, Locked Door. |

Several puzzles in the later Wizardry games ultimately boiled down to this, though quite often the nature of the item you need is only hinted at, and said item is hidden half a world away. Also common in reverse: you find the strange or seemingly useless item first, then much, much later, find the place you need that odd item. | |

Almost all dungeon levels in the Dark Cloud series feature this. The dungeon item will invariably be dropped by one enemy on the floor upon defeat, which will be used to travel to the next floor. Occasionally, you'll find keys that will open up doors or bridges that block off parts of levels. | |

Featured all over the place in Prodigal, being a game that consists mostly of dungeons. In the post-game and New Game Plus you can progress a bit faster by purchasing Normal Keys, but these can only get you so far because some places have Crystal Keys, which you have to move from one place to another without taking any damage at all or it will break (thankfully it respawns so you can keep trying), and Daemon's Dive has Divine Keys, which can only be found within that particular dungeon to stop you from relying on Normal Keys that were acquired elsewhere. | |

Eternal Darkness has many of these puzzles. One notable example is the "Staff of Ra"-style puzzle where the character finds a rod and a lens, puts them together and places the staff on a pedestal. The sunlight (or whatever it is) coming from above focuses through the lens into a beam, which must be rotated to reveal reflective panels before finally unlocking the door. | |

Wolfenstein 3-D and the later Quake both have gold and silver keys (also keycards and runekeys in the latter, depending on the level aesthetic). Most of the mid-90's "Doom clones" like Duke Nukem 3D, Dark Forces, and Blood also copied this idea. Blood is noteworthy in that it features six different key types (dagger, eye, fire, moon, skull and spider), though levels rarely feature all of them at once. | |

raocow refers to these as "item babysitting" in Super Mario World ROM hacks: finding a key and bringing it back to a lock you passed, finding a springboard and bringing it back to a high jump you passed, etc. He's not particularly fond of these puzzles, but it's about all the complexity and nonlinearity one can manage in the Super Mario World engine. | |

Mario Party 7: The Bowser minigame Treasure Dome! has a solo player open five chests, one after another, and has only 30 seconds to do so. At the start of the minigame, the player grabs the key at the center and has to see which chest is opened with it, and that chest will have the key that opens one of the other four chests, then get the next key to see which of the remaining three chests opens up, and so on. The fifth chest opened guards the key that allows the player to open the exit door. | |

One of the stranger examples appears in Doom RPG, in which the 'lock' is a large database with a piece of vital information buried in it somewhere, and the 'key' is getting an NPC to loan you a Beginner's Guide to SQL so you can look up the right command. Regrettably, the limits of the game engine prevent players who already know the command they need from bypassing this. | |

Doom The closest thing there is to a puzzle in the classic games. There are three different keys (red, blue, and yellow, all three in "keycard" and "skull key" variants, but only one variant appearing per level), each of which opens matching-color doors within the same level. Which keys appear (if any) depends on the level, and the format depend. Later on, fans cooked up source ports that allow the game to distinguish between key formats as well, so in custom WADs, a man-made electronic keycard doesn't open. Doom³: Pops up in three different flavors. The most common is restricted-access doors that require a scan for your PDA clearance, and you have to find the PDA of one of the people authorized (which the door's interface panel helpfully provides a list of) to download the clearance and gain access; sometimes, you have to find an actual keycard* that plays the classic "item picked up" sound of the classic games; and finally, certain areas have to be unlocked by accessing a security terminal. DOOM (2016) varies things up a bit by occasionally making the "key" you have to find a severed hand from one of the mangled corpses lying around. Or an entire torso. |

In Girl Genius the fragmented AI of Castle Heterodyne tasks the prisoners trapped in it to work on repairs with tasks like this on occasion by locking them in a room or wing of the castle and not letting them out until that section is repaired. Due to the state of the castle, the fact that there is no way to get food to individuals trapped in this manner, and the fact that the castle just can't pass up the opportunity to murder its occupants in amusing ways this often leads to the deaths of all involved rather than any repairs and opened doors. | |

Chip's Challenge makes use of color-coded keys and doors in many ways for this purpose, with the player being required to collect a certain number of chips each level to get through the gate to the exit. Two examples in particular stand out: Level 135 (Trust Me) requires Chip to find one yellow key to open the yellow door blocking the exit. The problem is that, while there are multiple keys, many of them are either tied to deadly traps or simply inaccessible; as a result, he has to navigate through the whole level to figure out which is the right key to collect. There's a glitch in the Microsoft version that allows an earlier key to be grabbed without consequence to finish the level more quickly, though. Level 137 (Goldkey) features many yellow keys as well as many yellow doors. The catch here is that certain doors have to be opened in a particular order, as going through either a wrong path or a certain area too ahead of time will render the level Unwinnable by Design, forcing the player to restart it. |

Doom³: Pops up in three different flavors. The most common is restricted-access doors that require a scan for your PDA clearance, and you have to find the PDA of one of the people authorized (which the door's interface panel helpfully provides a list of) to download the clearance and gain access; sometimes, you have to find an actual keycard* that plays the classic "item picked up" sound of the classic games; and finally, certain areas have to be unlocked by accessing a security terminal. | |

A major mechanic in the Zaltec series of gamebooks. The puzzles don't have an explicit "if you have item X, you may proceed" condition but rather the items are parts of visual puzzles that can only be solved once you've actually seen the item, thus preventing cheating (and serving as an actual puzzle). | |
