History ArtificialStupidity / OtherGames

** In ''Yu-Gi-Oh Dungeon Dice Monsters'', any character not found in the anime will just summon around their Heart Points and will eventually use up all their summons. They will then be unable to do anything, allowing you to have as many rolls as you need to summon anything. The Exodia pieces can be summoned this way, and by summoning them all, you get an instant win, and the AI is powerless to stop you. You can beat ''anyone'' in the game with an equally inane strategy. There are summonable "items" in the game which take the form of chests. Only the summoner knows what's in the chest, and it activates when a monster passes over it. The AI will ''never'' run over your chests, in the expectation that it might be a trap (and, to be fair, it might). However, it is possible, by spamming cheap summons, to block your opponent so that the only path to your heart points is through the chest. At which point, the AI will helpfully sit around, waiting for you to kill them. Also, the AI will never attack your monsters unless it can one-shot-kill the monster, ''and usually not even then.'' The AI will never use its own items even if they're beneficial, so you can use their items to power up your monsters or even''revive your destroyed monsters.'' The AI will never use its monsters' special effects (the sole exception being Orgoth the Relentless) even if they have the crests to do so. You can be ''right next to the enemy's Die Master'' getting ready to secure the winning strike, and the AI ''still will not attack your monster'' or attempt to protect itself. Again- with rare exceptions. The AI will also head straight for your die master and get stuck in corners and dead-ends as a result. The AI will even select dice that make it physically impossible for the AI to summon a monster.

** Pestilence itself is a global enchantment that deals 1 damage to EVERYTHING ON THE FIELD (including BOTH players) for 1 black mana, repeated as long as you have black mana/creatures (Pestilence is destroyed if no creatures are on the field). Lord of the Pit is a creature with 7 power (deals 7 damage), 7 toughness (can take 7 damage), is flying (can only be blocked by other fliers or creatures with "Web"), and has FIRST STRIKE (His 7 damage can be spread however he likes first, and then any defenders still alive deal damage to him). This came at the drawback of needing to sacrifice a creature every round, if you didn't, he did 7 damage to his controller. Many a game was won by simply wiping the creatures away, or stalling until your opponent ran out.

* ''Website/{{Akinator}}'' can be surprisingly daft at times, since he doesn't really understand the questions he's asking (they're all user-contributed); as a result, he may keep asking you almost identical questions, or directly opposite ones ("Is your character real?" followed by "Is your character fictional (does not really exist)?") Of course, he'll ask if they have black hair and then ask if they have blond hair, plus the always entertaining "Asks if they're from one universe, is told yes, guesses a different universe". This is likely the only program to think ''Franchise/MassEffect'' and ''VideoGame/{{Halo}}'' are the same universe. And sometimes it will ask you if you've met/said hello to the character ''after'' you've confirmed it's a fictional character or dead historical figure. Apparently it believes you might be ''Literature/ThursdayNext'' or a time traveler.

* A few missions in "VideoGame/DestroyAllHumans" require the player to follow certain characters to specific places or hypnotize them to perform a certain task. One mission in particular has the player escort a character back to their saucer, and once they start running, they will not stop for ANYTHING. This includes a busy street, where [[https://youtu.be/qqGrLGEdWeg?t=2h29m25s this]] almost inevitably happens.

* If you've ever played a video game adaptation of a game show, you've probably encountered computer contestants that couldn't answer simple questions correctly. ''Series/PressYourLuck'' for the Wii is one of the {{egregious}} examples, with computer opponents answering questions such as "What animal do we get milk from?", "What is 36 divided by 6?", or "How many months are in a year?" wrong.

* ArtificialStupidity has been with us since the [[OlderThanTheNES days of]] Pac-Man. Because of the way the AI (highly advanced for the time) was programmed without any RNG whatsoever, patterns were discovered that guaranteed that the ghosts wouldn't eat you, even up to [[KillScreen level 255]]. One of the two big innovations on the Pac-Man formula that made Ms. Pac-Man so big was just randomizing the location to which each ghost went at the start, making such pattern play unreliable.

** But if you want to ''end'' the game rapidly, you can just type in "melon" and watch as a greatly offended Trip kicks you out of the apartment. The game's speech recognition system detects when players say a vulgar word and makes Trip and Grace react appropriately. However, the game also tries to incorporate various slang terms as well, which can catch a player off-guard when one of these words is typed in a perfectly innocent context sees you shoved out the door. It's not the only example of a seemingly innocuous word causing Trip to prudishly force you out of the apartment, but "melon" is by far the most famous example.

* The final boss of ''VideoGame/MagicTheGathering: Battlegrounds'' has the ability to cast any spell in the game, any time he likes. Theoretically this means he should be able to spam you with giant monsters while countering any spell that you try to cast. Instead, he just sort of hangs around not doing much, and can be trapped in a loop by summoning the same low-level Mook over and over again. This is, of course, intentional, as that level of power would by simply impossible to oppose if he used it in anything like a sensible fashion, but it's rather unsatisfying to beat a boss that could {{curb stomp|Battle}} you at will for no other reason than that he was too dumb to actually ''do'' it.

** Total Defence Shogun is particularly weak in the hands of the AI. It has 1550 ATK, 2500 DEF, and ''it can attack while in defence mode''. Whenever they play/use/control one however, they will always switch it to attack mode. So, basically, the AI weakens the monster by 950 points, AND opens themselves up to Life Point damage voluntarilly.

** In Yugioh: Dungeon Dice Monsters, any character not found in the anime will just summon around their Heart Points and will eventually use up all their summons. They will then be unable to do anything, allowing you to have as many rolls as you need to summon anything. The Exodia pieces can be summoned this way, and by summoning them all, you get an instant win, and the AI is powerless to stop you. You can beat ''anyone'' in the game with an equally inane strategy.

The AI will even select dice that make it physically impossible for the AI to summon a monster.

** ''Videogame/YuGiOhReshefOfDestruction'' mainly averts this, due to having a much simpler ruleset that's harder to screw up, but the computer will always attack your cards if they are face down in defense mode unless their monsters have 0 Attack. This will happen even if you use a card to cover up previously seen monsters.
** An app called Yu-Gi-Oh! Duel Generation generally has [[ArtificialBrilliance incredible AI.]], but Pot of Duality seems to cause some hiccups. Instead of taking something useful like Mirror Force, they'll take Skelengel. They also take a Field Spell card when they already have ''the exact same card'' already on the field instead of a monster to defend their life points.
** Yu-Gi-Oh! Destiny Board Traveller has this when the Outer Space board is used. The AI will heavily prioritize summoning monsters, and generally ignore the special spaces, which is a very bad idea on this board, since if a player doesn't go to a special space for 5 turns, they will lose 1000 Life Points. It is very possible to win on this board with this being the only way your AI opponents take any damage at all.

* The final boss of ''MagicTheGathering: Battlegrounds'' has the ability to cast any spell in the game, any time he likes. Theoretically this means he should be able to spam you with giant monsters while countering any spell that you try to cast.

** Then you have Mokuba, for whom this trope is invoked ''intentionally''. [[WebVideo/YuGiOhTheAbridgedSeries What a digital dummy!]] To give you the idea of how dumb he is, his second strongest monster is [[PromotionalPowerlessPieceOfGarbage Kanan The Swordmistress]], a normal monster with 1400 ATK and 1400 DEF. He summons none of his monsters in defense mode, letting you just keep knocking them down. His entire strategy is to draw ''one'' monster, Cyber Stein, which has the ability to summon a fusion monster. This is the only way you can lose to him, because if he manage to do this, he'll summon ''Blue-Eyes Ultimate Dragon''. Which he will gleefully prompt to crash and burn into your obvious Mirror Force/Sakuretsu Armor/Maneater Bug/Penguin Soldier/etc. Or even worse, into your more obvious Magic Cylinder, which will cause him to ''kill himself'' without fail[[note]]Activating Cyber Stein costs 5000 life points. Magic Cylinder causes an attack by your opponent's monster to be cancelled and the ATK of the monster to be substracted from his life points. BEUD has 4500 ATK. A normal match has a player begin with 8000 life points[[/note]].

* This plagued computerised Go engines (especially when compared with computerised Chess engines) until a few years ago, with them being trounced by professional Go players even when given substantial advantages. However, the latest version of AlphaGo, an AI whose design represents a major breakthrough in computer Go, seems to be far stronger than any human player, going undefeated against top professionals. Part of the reason it took so much longer to build a professional-level Go program is that the search space is much larger compared to Chess — there are typically two or three hundred possible moves available to either player, and most games last over two hundred moves — so it's not feasible to analyze all possible sequences for more than a few moves ahead.

* This has plagued computerised Go engines (especially when compared with computerised Chess engines), with them being trounced by professional Go players even when given 25 stone advantages... The latest Go AI can win with a 9 stone advantage, and has been stated that it's up to good amateur levels. In Go the problem space is much larger. While both go and chess have a finite number of moves per turn, determining the possible moves in chess is a matter of thinking of each piece and seeing where they can land and if it's open, whereas in go it's not a matter of "which of these 32 pieces can move where?" so much as "which of these 300-odd spots ''should'' pieces go on?", which doesn't just make calculation slower and more memory intensive, but also makes the heuristics harder to work on, too.

** In ''Eternal Duelist Soul'', the AI doesn't know how to use Special Summons correctly. Mai has a card in her deck called Elegant Egotist, which allows her to Summon a Harpie Lady or a Harpie Lady Sisters from her hand or deck, as long as there is already a Harpie Lady on the field. Harpie Lady Sisters has 1950 ATK and 2100 DEF, and can ''only'' be summoned through Elegant Egotist's effect, while the regular Harpie Lady has 1300 ATK, 1400 DEF, and no effect or summoning conditions. Mai will ''always'' play Elegant Egotist and choose to bring out a second Harpie Lady, even if the player's Monsters have more than 1300 but less than 1950 ATK, and therefore makes one of her cards a total waste of space.

* Computer controlled helpers in ''VideoGame/KirbySuperStar'' have their uses, but don't expect them to live very long. Fortunately they're easy to replace. Also, your AI allies in ''VideoGame/KirbyAndTheAmazingMirror'' can be counted on for jack squat. They'll mill around in random areas, getting random abilities [[TheComputerIsACheatingBastard (including abilities not in their current area)]], and if you call them to your side...well, it's usually for one of three reasons: a boss fight, the fact that they bring health-restoring food with them, or one of them somehow snagged the [[VideoGame/SuperSmashBros Smash]] [[GameBreaker ability]] and you're just waiting for them to screw up so you can use it yourself.

** Macro Cosmos Decks turn most games against the AI into a comedy of errors. Macro Cosmos [[LostForever removes any card that would enter the Graveyard from play,]] meaning that many strategies centering around the Graveyard become fairly crippled. A human player would attempt to destroy Macro Cosmos as soon as possible, then initiate their normal strategies. Not the AI, which will completely ignore Macro Cosmos and continue to play as if it wasn't there. You haven't seen ArtificialStupidity until you've seen an AI use Foolish Burial to remove its ''own [[GameBreaker Treeborn Frog.]]''
