Do we have to write about Tony Stark?Tony does not have to be your main character. He does not need to be mentioned in the fill. Any character that has been featured in media with Tony Stark (comic, cartoons, video games, or movies) can be considered.
What do I do with that space in the middle?
It’s a free space, make anything you want as long as it meets the minimum requirements.
Can we make a Chaptered Story, or continue a fill after the close of the bingo?
YES
If you write a story about mermaids for one square, you may then continue the same story in your next square about mating rituals. If you end up with 25 fills all in the same AU, and cover each square in one chapter, that’s allowed. And, we have to say, pretty impressive!
Can we continue or Work in an AU we’ve already written?
Short Answer: Use your best judgement
This is a little trickier, because a bingo is supposed to be an easy entry event, for both writers and readers; that said, IF your Bingo Work mostly stands alone (Steve and Tony getting engaged for the Square “Put a Ring on It” when this particular Steve and Tony have been in your “Flamingo AU” for a while, that’s fine. It’s good to give readers little glimpses from longer works to tempt them into reading.
The entry needs to stand alone – a new reader should be able to understand what’s going on without wondering why Natasha is suddenly Tony’s twin sister…
Can we combine Multiple Prompts into a single Fill?
No
If you have (S1) Cave, (S2) Ho Yinsen, and (S3) HumDrumVee, you cannot do one 300 word fill about a nightmare where Tony’s in the cave, dreaming about the attack and Yinsen wakes him up. That is called a grabbag challenge and is not the purpose of this event.
But you can create a chaptered work, in which chapter one fills S3, chapter two fills S2, and chapter three fills S3. Each chapter will have to meet the minimum word count.
Can we Collaborate on fills?
YES
If you and another bingo participant want to co-write a square, you may if: You write/draw double the amount for a single fill (so you are still meeting the obligations of the fill for your card.) You can each use one fill on your cards. (For example, Mary Jane has “Coffee Shop” on her card and Gwen Stacy has “first date” on her card) MJ and Gwen can write about a first date at the coffee shop, and the fill must be 600 words or more to count for both participants. You may also collaborate if the other writer/artist is NOT involved in our bingo at all or doesn’t have a square specific to the fill, with the same requirements of doubled length.
Likewise, if two artists want to collaborate, they can do that; one does the penciling, and one inks, or one does the characters and one does the background. Likewise, the drawing has to be 600 x 600 pixels or 6x6 inches to count as the double fill.
Or one artist/one writer wants to do a 300 word fic and a little drawing that goes with it.
All of these things are perfectly fine and allowed.
Can we use our fill in more than one Bingo/event?
YES
If you have “BDSM: Bondage” in your @mcukinkbingo card and “KINK: Held Down” on your Tony Stark Bingo card, and you want to just write one story and cross-post, that’s also allowed, provided it’s okay with the mods in charge of the other event. (I already know Kink Bingo is okay with it, which is why I used them as a specific example. Other mods may have other rules. Some events, especially bangs or exchanges, may want entirely unique material for their events.) Again with the same restrictions: the story must be the length of both minimum requirements combined (if one bingo’s minimum is 250 words and the other is 500, it has to be 750 words.)
Can I write real people fiction?
No Real People Fic. We’re celebrating the characters Tony Stark and other Iron Family, not RDJ or Chris Evans or Tom Holland, etc.
What does this fill mean?
Comic Book Wiki
Marvel Cinamatic Universe Wiki
Urban Dictionary
Tropes Wiki
Here are some useful resources. Most of the prompts came from participant suggestions, the comic book/movie lists of characters, locations, and objects, are kinks, or came from the list of Tropes. Chances are good, you can find what you’re looking for on one of these sites. Please consider using the sites.
If not, the mods will take questions on the FAQ channel in Discord, or via Tumblr asks.

Literally, we do not care. We’re not the fic police, and will not be checking your work. If you think it counts, it counts.
My fill says Park. Does this mean parking the car, or hanging out in a park or–
YES. The fill is up for you to interpret it however you want. The mods are not going to police your fills for our interpretation of the fill. Go wild, do what you want! Anarchy in the A03!
