The number seven, as a source of luck.

A Subtrope of RuleOfSeven. See also NumerologicalMotif, MagicalSeventhSon, and MagnificentSeven.


[[folder: Advertising ]]

* When Lucky the Leprechaun added marshmallow Rainbows to his Lucky Charms, bringing the number up to eight, a few older leprechauns objected, saying seven was luckier, and he cereal couldn't have eight. [[IDoNotLikeGreenEggsAndHam They changed their minds after tasting it.]]


[[folder: Anime And Manga ]]

* The seventh volume of the ''Manga/LuckyStar'' manga has a tiny "Lucky" beside the volume number.
* Lampshaded by TOM when it was revealed that both ''Anime/SamuraiSeven'' and ''Anime/EurekaSeven'' would be new additions on the revived Creator/{{Toonami}}.
* In ''Anime/YuGiOhZEXAL'', a duelist named Charlie [=McCoy=] uses a monster called "Number 7: Lucky Straight" which gives him supernatural luck.
* Subverted in ''Manga/FairyTail'' -- July 7th, x777 was when the dragons disappeared and Lucy's mother died. Played straight with the English release of manga volume 7, released on July 7th in 2009.
* Seven [[OnePiece Shichibukai]]. There were also seven Straw Hat Pirates for a considerable length of time (then they gained more crewmembers).
* In ''Anime/JewelpetSunshine'', the Wise Ones, who are destined to save the world in its DarkestHour, are seven people.
* ''Manga/GunslingerGirl''. Triela's {{handler}} Victor Hilshire keeps giving her teddy bears as gifts, being MaternallyChallenged and figuring that GirlsLoveStuffedAnimals. Eventually their relationship develops enough for him to ask what she wants, but she just asks for another bear so she'll have seven of them. To her annoyance, she gets another bear from someone else, leaving her with eight bears.


[[folder: Film ]]

* Subverted in ''Film/{{Unstoppable}}'': Train #777 (888 in RealLife) is loaded with hazardous chemicals and speeding towards a populated area.
* Referenced in the title of ''Film/LuckyNumberSlevin'', which is a pun on the phrase and Slevin, the main character's name.
* ''Film/SnakeEyes'': Referenced by Santoro when he sees the {{Pit Girl|s}} holding the sign for the 7th round in the boxing fight. She later unwittingly distracts Santoro when the Secretary of Defense is assassinated at the match, so she's probably not a very good token.
* Film/JamesBond is agent 007 in MI6. ''Film/TheSpyWhoLovedMe'' was first released on July 7, 1977, or 7/7/77.


[[folder: Literature ]]

* ''Literature/HarryPotter'' - According to WordOfGod, seven is a lucky number in the Potterverse. Hence we have: seven books; seven years at Hogwarts; six Horcruxes plus the fragment of soul still in Voldemort's body [[spoiler: or so he thinks - Harry is actually the seventh Horcrux, which proves his downfall.]] "Isn't seven the most powerfully magical number?"
** There are also seven Weasley siblings. [[spoiler: Until the seventh book, anyway...]]
* Literature/{{IT}} : The last third of the book continually drops reminders that for their particular brand of magic to work, all seven members of the Losers club have to be present. In the film version, they actually refer to themselves a "Lucky Seven."


[[folder: Live Action TV ]]

* Series/{{Survivor}} season seven winner Sandra Diaz-Twine became the first (and, so far, ''only'') two time winner by winning season twenty, seven years after her first win.


[[folder: Music ]]

* The {{eurobeat}} song "777" by Fastway, unsurprisingly, is about gambling and winning big.


[[folder: Religion and Mythology ]]

* The [[ Seven Lucky Gods]] of Myth/JapaneseMythology.
* Inverted with the concept of the SevenDeadlySins. And played straight with the opposing concept of the SevenHeavenlyVirtues.
* In Judeo-Christian numerology, Seven is considered the number of God. Consequently the number shows up a ton in Literature/TheBible, especially in [[GrandFinale Revelation]].


[[folder: This Very Wiki]]

* On the SuperWeight scale, 7 is the highest -- representing AuthorPowers, {{God}}, etc.


[[folder: Toys ]]

* Toys/MachineRobo, or [[WesternAnimation/ChallengeOfTheGoBots Gobots]]: Four figures marked #7 are all Gaurdians (Friendly Gobots).
** Turbo = [=MR7=]
** Baron Von Joy = DX Scale Robo #7
** Rest Q (Anime Reissue) = [=MRB7=]
** Leader 1 (Also anime reissue) = [=MRJ7=]
* {{Transformers}} probably hates this trope:
** Bluestreak (later Silverstreak) was Diaclone Car Robo #7, but was not so popular as Prowl (Car Robo #13).
** On the Microman side, Micro Change #7 was designated as one of the evil Decepticons!
* In Toys/{{Bionicle}}, all related characters were released in groups of six. This was reflected in the story as well, with six tribes, six leaders, and six [[TheHero Toa]] to protect them. Later on down the line, a seventh Toa is added into the mix. Lucky number, right? Wrong. Apparently, Toa groups can be any number. Two, six, fifteen, a hundred anything. Six is preferred, but it can be anything else. Except seven. Seven means [[TheProphecy bad juju is about to go down]].


[[folder: Video Games ]]

* All over the place with ''VideoGame/PunchOut'' Wii's version of Aran Ryan. He always gets up from a knockdown on the seventh count, you can hit him seven times when he's stunned, and sevens pop up in his challenges in Exhibition Mode. He's Irish, so it's a "lucky seven"/"luck of the Irish" gag.
* ''Franchise/FinalFantasy'':
** ''VideoGame/FinalFantasyVII'' (figures) causes a character to go berserk if their HP hits 7777, attacking all enemies up to 63 times for 7777 damage per hit: the only enemies that can withstand this and not die are the {{Bonus Boss}}es. The Lucky Seven concept continues in the prequel ''VideoGame/CrisisCore'', where getting three Sevens on the DMV (the battle system's slot-machine gimmick) will level up your character.
** ''VideoGame/FinalFantasyIX'' contains the attack "Lucky 7s", a ShoutOut to the above.
** In ''VideoGame/FinalFantasyVI'', Setzer has a slot-machine-like attack, and getting three 7s kills all enemies.
** In ''VideoGame/FinalFantasyX2'', getting all 7's on the Lady Luck dresssphere's slots skill will result in an attack called "CONGRATS!", which inflicts a OneHitKill to all enemies and yields many bonuses for the party.
* The seventh ''VideoGame/{{Touhou}}'' game is the only one to feature the "Supernatural Border" system, which can and will save your life on occasion. It is also the first game in the series to have visible hitboxes.
%%* ''VideoGame/{{Xenoblade}}'': "7th", or [[spoiler:Fiora, the seventh playable character in the party]], as this is referred to by users on boards. Saying ''why'' this is important is [[FirstEpisodeSpoiler incredibly spoileriffic]].
* ''VideoGame/MarioKart7'' features an item called "Lucky 7", which grants the player seven items at one time.
* In the original ''[[VideoGame/StarFox1 Star Fox]]'', the alternate final boss is a Slot Machine. After a little bit of thinking, you'll realize that getting Triple 7s is how you beat it. [[LuckBasedMission Getting it]] [[MarathonBoss is a whole]] [[GoddamnedBoss different story]].
* ''Franchise/KingdomHearts'' has the Seven Princesses of Heart, a group of seven young girls whose hearts are completely devoid of darkness.. When brought together, they open the doorway that leads to Kingdom Hearts, which is the very reason why the BigBad is after them. ...At least in the first game. In ''VideoGame/KingdomHearts3DDreamDropDistance'' it's revealed that [[spoiler: their hearts were born from the seven fragments of light from the ''x''-blade. When faced against thirteen darknesses, namely Xehanort's true Organization XIII, the resulting clash will ensure the recreation of the ''x''-blade, which is exactly what Xehanort seeks.]]
* In ''VideoGame/SuperMarioBros2'', getting all 7's on the bonus reels nets you ten {{One Up}}s..
* In ''VideoGame/SuperMarioGalaxy2'', getting 77 stars will prompt Lubba to say "77 stars! How lucky!"
* The Trickster class in ''VideoGame/FireEmblemAwakening'' learns a skill called Lucky Seven. It raises hit and avoid rate by 20 for seven turns at the start of a battle, both stats returning to normal afterwards. Fittingly, Trickster is the default class of [[AscendedExtra Anna]], whose base luck stat is already high and is sure to get even higher as she has one of the highest Luck growths in the game. In the same game, Cordelia is recruited in Chapter 7, her starting level is 7, and her birthday is July 7th.
* In ''VideoGame/CookieClicker'', most of the numbers associated with the bonus Golden Cookies are strings of 7s (the bonus to cookies per second they can give is X7 and lasts for 77 seconds, the upgrades for them have costs in strings of 7s, the achievements for them involve clicking 7, 27, 77, 777, and 7,777 of them).
* In ''VideoGame/FortuneStreet'', most Venture Cards with a 7 in the number have some very positive effects. Most notably Venture Card 7, which increases all the drawer's shop values by 7%.
* Acquiring exactly 777G at any point in ''VideoGame/MonsterWorldIV'' will earn you 7000G. If you're lucky to get this bonus as early as you can, then you can easily afford some good equipment early on.
* In ''VideoGame/FallenLondon'', seven is widely known as "[[ArcNumber the number]]". An {{inver|tedTrope}}sion, though, as it's "the number" for "Seeking Mr Eaten's Name", a sidequest most famous for being [[PressXToDie incredibly costly and deliberately unpleasant]].
* ''VideoGame/Idolish7'' The titular idol unit has Seven Members.

* In ''Webcomic/{{Sinfest}}'', [[ God rolls them. Not so lucky for Slick]].

* {{Inverted}} with the Wiki/{{SCP Foundation}}'s mobile task force Kappa 42, AKA Lucky Seven. Of its members, three are missing presumed dead, two have committed suicide, and one has been terminated.


[[folder: Real Life ]]

* As a homage to this trope, the highest jackpots on a slot machine is often assigned to three 7s (which, perhaps not coincidentally, add up to the ideal number in blackjack).
* Seven is the most likely roll of a pair of standard 6-sided dice. In craps, you can win by rolling a seven (or eleven) first, and lose by getting seven on any subsequent roll. The fact that seven is the most likely sum for the outcome of rolling two dice (with a probability of 1/6) is likely the origin of the whole "seven is a lucky number" superstition.
* [[ Zayin]] is the 7th letter in most Semitic abjads (writing system). It is the source of both the modern "7" and "Z", and also meant "sword" (several proto-versions look like basic swords, and the Arabic derivation bears a slight resemblance to a scimitar).
* UsefulNotes/{{NASA}} seems to have held this view of the number 7 during their Mercury program. There were seven pilots recruited to be astronauts for the program and, despite using a different numbering system internally, each manned capsule had the number 7 in their callsign.[[note]]Freedom 7, Liberty Bell 7, Friendship 7, Aurora 7, Sigma 7, and Faith 7[[/note]] Considering the success of the program and their [[Film/Apollo13 later track record]] with [[ThirteenIsUnlucky the number 13]], they may have been on to something....
