The number seven, as a source of luck.

A Subtrope of Rule of Seven. See also Numerological Motif, Magical Seventh Son, and Magnificent Seven. Contrast 13 Is Unlucky and, in Asia, Four Is Death.

Notably, seven is the most likely number to get if you roll two dice, making it significant in gambling.

Examples:

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 the cereal couldn't have eight. They changed their minds after tasting it.

• Lampshaded by TOM when it was revealed that both Samurai 7 and Eureka Seven would be new additions on the revived Toonami.

To her annoyance, she gets another bear from someone else, leaving her with eight bears.

Fan Works

• In Half Past Adventure, this trope is subverted when the numerology-obsessed character Vesper considers the number seven to be bad luck; apparently this is an aspect of "Breakfastian numerology".
• Danny and Kara: Danny and Kara are each other's seventh date and they chose each other at the end of the program.

Films — Live-Action

• Subverted in Unstoppable: Train #777 (888 in Real Life) is loaded with hazardous chemicals and speeding towards a populated area.
• Referenced in the title of Lucky Number Slevin, which is a pun on the phrase and Slevin, the main character's name.
• Snake Eyes: Referenced by Santoro when he sees the Pit Girl 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.
• James Bond is agent 007 in MI6. The Spy Who Loved Me was first released on July 7, 1977, or 7/7/77.

Literature

• Harry Potter: According to Word of God, 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 or so he thinks - Harry is actually the seventh Horcrux, which proves his downfall. "Isn't seven the most powerfully magical number?"
• 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 as "Lucky Seven."

Live-Action TV

• The first seven Kamen Riders are known as "the Seven Legendary Riders".
• 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.

• Lucky Seven was also the name of the end game of Spellbinders, an unsold 1978 pilot for NBC from Goodson-Todman.
• There was an ABC show called Lucky 7 that focused on seven gas station workers that won the lottery. It got canceled after two episodes.

Music

• The eurobeat song "777" by Fastway, unsurprisingly, is about gambling and winning big.
• Dice of Hypnosis Mic has this all over his character, being the resident gambling man. Not only is his Character Song "3$EVEN", several sevens are hidden in his bio (with his weight even going up to 77kg).

Myths & Religion

• The Seven Lucky Gods of Japanese Mythology.
• Inverted with the concept of the Seven Deadly Sins. And played straight with the opposing concept of the Seven Heavenly Virtues.
• In Judeo-Christian numerology, Seven is considered the number of God. Consequently the number shows up a ton in The Bible, especially in Revelation.

Professional Wrestling

• Probably not intentional, but bears noting: Kenta Kobashi used the Burning Hammer in seven matches. He won all seven.

Toys

• Machine Robo, or Gobots: Four figures marked #7 are all Guardians (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 later re-released as the Decepticon Browning (though he did make a Heel–Face Turn later on).
• In 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 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 bad juju is about to go down.

Video Games

• All over the place with Punch-Out!! 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.
• The Communitree: The "Corpses as Fertilizer" upgrade costs 7.77e777 lollipops. It makes drop candies boost "Improved Fertilizer"'s effect.
• Final Fantasy:
  • Final Fantasy VII (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 Superbosses. The Lucky Seven concept continues in the prequel Crisis Core, where getting three Sevens on the DMV (the battle system's slot-machine gimmick) will level up your character.
  • Final Fantasy IX contains the attack "Lucky 7s", a Shout-Out to the above.
  • In Final Fantasy VI, Setzer has a slot-machine-like attack, and getting three 7s kills all enemies.
  • In Final Fantasy X-2, getting all 7's on the Lady Luck dresssphere's slots skill will result in an attack called "CONGRATS!", which inflicts a One-Hit Kill to all enemies and yields many bonuses for the party.
• The GFRIEND Tree: The Lucky Number achievement completed by reaching 7.77e77 popularity.
• Halo: Master Chief is John-117, and, as Cortana explains in the intro to Halo 3, the one thing that sets him apart from the other Spartans is his good luck. Notably, the protagonist of Halo: Reach is Noble Six, who's no less skilled than the Chief, but as their callsign implies, isn't as lucky, which is why they die at the end of the game.
• Touhou Youyoumu ~ Perfect Cherry Blossom is the only Touhou Project game 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.

• Star Fox:
  • In the original 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. Getting it is a whole different story.
  • Star Fox: Assault inverts this with the Corneria stage, which is even worse for wear. Pepper is also forced into a Face–Heel Turn, leading to his transformation into the level boss.
• Kingdom Hearts:
  • The Seven Princesses of Heart are 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 Big Bad is after them... At least in the first game. In Kingdom Hearts 3D [Dream Drop Distance] it's revealed that 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. To protect the Princesses, the heroes instead decide to assemble seven Keyblade wielders as the Guardians of Light, even though they know that they are still playing into Xehanort's hands.
  • Kingdom Hearts III introduces the "New Seven Hearts," who have inherited the light of the original Princesses of Heart after they fulfilled their duty. Xehanort seeks to gather the New Seven Hearts in case the heroes fail to assemble the Guardians of Light. Kairi is the only princess who hasn't passed on her power, while Rapunzel, Anna and Elsa are possible candidates for the remaining six members.

  • Mario Kart 7: This game introduces the "Lucky 7" item, which surrounds you with seven items you can use as you want. But it's a double-edged sword and can backfire in several ways, as the items will also activate if someone else touches you, and can be lost entirely if you get hit by an item or course hazard. Its successor, the Crazy 8, spawns eight items to use at once.
  • Mario Party: Rolling either a double 7 or triple 7 in most installments will give you more coins than if you rolled the same of any other number. In the case of Mario Party 8, if the player eats a Twice or Thrice candy and rolls two/three of the same number, they will receive bonus coins. If they are lucky enough to roll double/triple sevens, the prize will be much greater. Twice Candy gives 10 coins for matching numbers and 30 coins for matching sevens, while Thrice Candy gives 30 coins for matching numbers and 100 coins for triple sevens.
  • In both Mario Party: Star Rush and Super Mario Party, Diddy Kong uses the Triple 7 Dice Block, which has a 50/50 chance of rolling to move either zero spaces or seven.
• Fire Emblem: Awakening: The Trickster class 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 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 Cookie Clicker, 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 Fallen London, seven is widely known as "the number". An inversion, though, as it's "the number" for "Seeking Mr Eaten's Name", a sidequest most famous for being incredibly costly and deliberately unpleasant.
• Idolish 7 The titular idol unit has Seven Members.
• In Fallout: New Vegas, the Luck stat influences how often you win at gambling, with 7 Luck being the point when the game starts tipping things in your favor. Subverted in the Fallout series as a whole, though, as the nuclear holocaust occurred in 2077.

• 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).
• 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 Considering the success of the program and their later track record with the number 13, they may have been on to something....
