Try Everything

""It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth.""

- Sherlock Holmes, "The Beryl Coronet".

""What an interesting and not-at-all arbitrarily random idea!""

- Strong Bad, pouring physical enhancement powder down a hole in the ground

""111-1111. Lois? Damn. 111-1112. Lois? Damn. 111-1113...""

- Stewie, attempting to figure out his home phone number

Subtrope of Trial and Error Gameplay. The inevitable process where, lacking a guide or any hope of solution after they'd exhausted the saner, more rational responses, people will, out of frustration, resort to using every single item/trying every option with every other item/funnily shaped spot on wall/steampunk eggplant. As the reasoning goes, you've tried everything else, why not Try Everything? Has varying chances of success and limited efficiency, but sometimes it's the only option. In real life too (commonly referred to as "Brute Forcing"). Can lead to people shouting, "Guide Dang It!", because, really, if you're just trying everything rather than reasoning through it, it's just as brainless as consulting a guide—and it takes a lot longer.

Related to Solve the Soup Cans, where it's about situations that are impossible unless this is employed. Also related to Speak Friend and Enter, where the solution is so obvious that you Try Everything before you consider it.

See also Million-to-One Chance. Compare Combinatorial Explosion, where the developers have the headache of coping with lots of items and only one way to do it. If the game tends to say "Adventure Narrator Syndrome" or "You Can't Get Ye Flask", a player who is Trying Everything will get very sick of hearing it.

Comic Books

 * One Asterix story sees Getafix deranged by a bash on the noggin, so they repeatedly hand him cauldrons and potion ingredients in the hope that he'll mix up a potion to cure himself.

Literature

 * This might go back to "Ali Baba and the Forty Thieves", where Ali Baba's brother forgets the password "Open, sesame!" and tries naming almost every other variety of grain.
 * Referenced in the third Aladdin movie: "Open... Caraway!!"
 * Also happens in the the Looney Tunes cartoon "Ali Baba Bunny"; Bugs and Daffy tunnel into the cave of a wealthy sultan. Seeing this, the sultan’s guard Hassan tries to activate the password, only to realize he has forgotten it, so he rattles off several different S-words (“Uh...Open, sarsaparilla? Open, Saskatchewan? Open, septuagenarian? Open, saddle soap?”) before eventually getting it right.
 * In Harry Potter and the Goblet of Fire, Harry has to get into Dumbledore's office, but he doesn't know the password. He does know that the password is always some type of candy, so he rattles off the names of every popular brand he can think of, like "Bertie Bott's Every Flavour Beans" (then he remembers that Dumbledore doesn't like those, so that's clearly not right), "Chocolate Frog", and "Sugar Quill", before throwing up his arms in desperation and shouting, "Cockroach Cluster!". And that is the password, which causes the bemused Harry to say “Cockroach Cluster? I was only joking …”

Action Adventure

 * StarTropics: The robot in the submarine will at some point ask you to enter a frequency to continue. You cannot progress until you do. Have you lost the letter that came with the instruction manual and are instructed to put in water? Well, it's only a three digit code, you can just try them all one by one.

Adventure Game

 * Quite common in Text Adventures (and other Adventure Games as well), where players tend to pick up everything and, when confronted with a puzzle, immediately try to apply everything to it.
 * A variant is the "guess the verb/noun/adjective or pronoun on rare occasions" puzzles, where the player has no choice but to resort to trying every variation on "use the thing on the other thing" until they find the right combination of verbs and nouns. For example, in one real-life example, "use whip on lion" gives a failure message ("You're too afraid of the lion!") while "whip lion" works perfectly.
 * One tried and true method when getting stuck in adventure games is the brute force method—try to combine every item with every other item until you find something that works.
 * Being an Adventure Game, Telltale's Sam and Max games include some of this. Of note, though, is how the manual encourages the player to try and shoot everything and anyone with Sam's gun.
 * The first two Discworld games suffer from such ridiculous (albeit hilarious) logic that this is required more often than not.
 * In the fifth episode of Strong Bad's Cool Game for Attractive People, when Strong Bad calls Videlectrix and asks for a tip on how to complete a Videlectrix game, he is advised to try to use everything with everything.
 * Although A Vampyre Story mostly averts this trope, it has one puzzle that appears to be designed around it—you have to take an item from a stack of several, try to use it, return to the stack, notice that one of these things is not like the others, then take that and use it to solve the puzzle. The problem is that until you try using the incorrect item the game won't acknowledge that there's anything notable about the rest of the stack, nor will it give you any other hint that might suggest a need to return to something you've apparently exhausted. It looks as though the designers expect you to get desperate and start trying everything to eventually bring you back to the stack to find out that "hey, this one looks different, let's try it."
 * PHANTASMAGORIA! The game where sometimes clicking on rats makes things happen and sometimes they don't happen! There's no real way to progress other than to just do absolutely everything you can.

Arcade Game

 * In The Tower of Druaga, uncovering the Inexplicable Treasure Chests could require passing through a certain set of points, killing enemies in a specific order, entering a particular combination of controller presses, or any number of other things the game couldn't be bothered to hint at. Players without a guide could consider themselves lucky if they figure out how to get the treasure on a floor and exit before the timer ran out and not have it be a poison potion. Of course, even players who tried absolutely everything were doomed to fail on the couple of floors where the treasure was a Missing Secret.

Platform Game

 * La-Mulana punishes players who resort to this:
 * One method is lightning bolts. It even warns you about this in the manual. It even shows you a picture of exactly what will happen to you. These usually are used when the developers don't want you to just whip everything in the room to try and solve a puzzle. Sometimes this behavior makes sense, because Lemeza is nominally an archaeologist; sometimes it just seems cruel.
 * The lightning bolts are particularly evil because the game has optional collectibles, some of which can only be found by randomly whipping every wall looking for secret areas. Then again, they are mostly optional.
 * Other times, this type of behavior is discouraged by only giving you one chance to solve a puzzle.

Puzzle Game

 * In Professor Layton and the Curious Village, solving many puzzles simply requires inputting a letter or single-digit number. Players who are stumped can Try Everything by going through the entire alphabet or number line until they hit the right answer.
 * Some puzzles, however, have no brute-force method. And others have multiple digits or use entire words; in those puzzles, trying the brute-force method would take ages.
 * Scribblenauts actually encourages you to do this.
 * And they really do mean everything.

Roguelike

 * In many, many Roguelikes, drinking your unidentified potions or eating the stuff you picked off that mysterious herb bush is not an option for the sane. When you're down to single-digit HP and attacked by an entire pack of jackals, it may be your only option: "What's this one? No... What's this one? Maybe this one?" *is devoured whilst blind, sick and invisible*
 * When things get really bad, there's also the unidentified scrolls game, which has a wider, riskier range of consequences. Resurrection? Destroy Armour? Summon Greater Demon? Teleport? or Dig?
 * How about wands? "I wonder what this does?" *Killer Elephant is turned into a newt* "How about this one?" *The Death Ray hits the monster! The Death Ray bounces! The Death Ray hits you! ...Do you want your possessions identifed?*
 * This is more or less the only way to collect all the voice clips in Baroque if you don't already know how to get each one. Punch every NPC, hit every NPC with a sword, shoot every NPC with your BFG, give every item to every NPC; repeat every time something plot-significant happens. Add to this the fact that there are over 300 items in the game, some NPCs only show up on certain floors of the Neuro Tower, and every floor is randomly generated... yeah. It gets pretty ridiculous. And yes, some of these are Lost Forever.

Role-Playing Game

 * The barrel puzzles in the Fade in Dragon Age II avert this. If you don't solve them within a certain number of moves, they vanish and a bunch of demons show up to attack you.

Stealth Based Game

 * The codec frequency for in Metal Gear Solid was actually given on the back of the game box, leaving the people who didn't work this out to resort to calling every frequency, because you couldn't progress without it.
 * The Colonel does say that it's on "the back of the CD case", but Snake was given a CD in-game not long before that you can't examine, whence stems much confusion, especially if you're not familiar with Metal Gear's trademark fourth-wall-breakery.
 * This was also a detriment to people who didn't have access to the CD case for either borrowing or renting the game, and thus had no way of finding out what it was even if they did know what the Colonel was talking about. Luckily, the needed frequency in question happens to be very close to the logical starting point of 140.00.
 * There was a similar experience in the original NES Metal Gear, made even worse by the fact that he would only answer your calls if you called him from certain rooms.

Third-Person Shooter

 * The only way to solve the mining laser puzzle on Therum in Mass Effect is to keep trying until you get it right.

Visual Novel

 * During the courtroom segments of Phoenix Wright: Ace Attorney, players who are stumped as to which piece of evidence to present often resort to Save Scumming and simply try presenting every piece of evidence until they get it right.
 * Doing this out of court has a running gag of Wright showing off his Attorney's Badge, something nearly every NPC responds to. Main characters (such as Maya and Gumshoe) will note he has shown them before.
 * If you're Genre Savvy, you never even bother with your attorney's badge, just to save time.
 * And in Ace Attorney 3, this will screw you over, in that the response for the correctly used item is the exact same as the usage for everything else. Well, for about 3 panels in, but if you're trying everything, that's all you're going to look before you reset.
 * Some of the games will actually punish players for trying to brute force their way in the trials by making it where the penalties are so high that sometimes you literally just have one shot to get it right. Of course, this will induce more Save Scumming.
 * Apollo Justice takes most of the fun out of Trying Everything outside court rooms by replacing the usually unique dialogue to a certain clue by replacing most of the dialogue with "I don't know" dialogue usually unless it's the key item.
 * Theresia: Dear Emile does its best to avert this by way of Booby Traps. Clicking on everything tends to result in getting peppered with arrows or stabbed by a flying knife.

Web Comics

 * The players in DM of the Rings respond to the entrance of the Moria mine in this way. They are on their way to chop down some trees to construct a battering ram when the DM ends up screaming the answer to them in frustration.

Western Animation
In the Looney Tunes cartoon "Ali Baba Bunny", Bugs Bunny and Daffy Duck tunnel into the cave of a wealthy sultan. Seeing this, the sultan’s guard Hassan tries to activate the password (which is, “Open Sesame”, naturally) only to realize he has forgotten it, so he rattles off several unusual S-words (“Uh...Open, sarsaparilla? Open, Saskatchewan? Open, septuagenarian? Open, saddle soap?”) before eventually getting it right.

Real Life

 * The old computer axiom PLOKTA (Press Lots Of Keys To Abort). Ritually performed by spreading both hands wide and mashing the keyboard in an effort to make your computer respond.
 * Security experts refer to something that tries to guess passwords by trying all of them as a "dictionary attack" (i.e., try every word in the dictionary), or a more thorough "brute force attack" (try every possible combination of letters/digits/symbols/etc.). A similar method, called "rainbow table", consists of getting one's hands on an encrypted password and comparing it with a huge table of possible passwords and their encrypted equivalents. The exception to this is the one-time-pad cipher; if you try brute forcing a one-time-pad encryption, you end up with literally thousands to millions of interpretations, and no way to know which was the correct one (that is what the key is for).
