• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE.

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 "I Can't Use These Things Together" or "You Can't Get Ye Flask", a player who is Trying Everything will get very sick of hearing it.

This is an interactive version of How Do I Shot Web?. May result from Enter Solution Here.

Examples of Try Everything include:

  • 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.
  • 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?
  • The codec frequency for Meryl 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.
  • 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.
  • 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!!"
  • 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.
  • 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. Which will screw you over in 1-4, since it's the only item that gets the old guy to respond. In the following case, if you show your badge to Gumshoe, he will still say you're "always flashing it around", despite you never having shown it to him before.
    • 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.
  • 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 Bads 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.
  • 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.
  • 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."
  • Theresia 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.
  • 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.
  • Scribblenauts actually encourages you to do this.
  • 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.
  • 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 only way to solve the mining laser puzzle on Therum in Mass Effect is to keep trying until you get it right.
  • The barrel puzzles in the Fade in Dragon Age 2 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.
  • 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.
  • 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. The answer is 747.
  • 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.
  • 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.
  • 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.

Real Life

  • 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.[1] 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).
  1. This is because good encryption methods use a "trapdoor function": basically, even if you know the encryption key, you can't directly reverse the process without a different key, or a brute-force effort that dwarfs the rainbow-table approach.
