Introducing: FOLDED [22,000+ mana prize pool] Manifold's first community social experiment/art project
Jul 13, 2025

🎴 Introducing: FOLDED

Manifold’s first large-scale social experiment & art project

A test of patience. A battle of routine. A war of attrition.

Join the experiment. Win the prize.
💰 12,000+ mana up for grabs -- and the prize pool is growing!


WHAT IS FOLDED?

FOLDED is a minimalist game with a single rule:

🕛 Check in once per day. Or be eliminated.

It sounds simple, but there’s a catch - it won’t stay that way.

🗓️ DAILY CHECK-IN

You must visit the check-in page once per day before midnight UTC.
Miss a day? You’re out. No second chances.

❌ ELIMINATION

Players who don’t check in are instantly eliminated.
Each day, the pool gets smaller. The tension rises.

💸 ENTRY FEE

To enter, send 2,000 mana to the prize pool via Managram.
Think of it as your ticket to the endurance games.

🏆 WINNER TAKES ALL

The last player standing takes everything.
Every mana from every eliminated player goes to the final survivor.

🔒 DIFFICULTY

It will become harder to check in over time.
The interface may evolve. The rules might twist.
Stay alert. Adapt. Survive.


HOW TO JOIN

Step 1: Pay your entry fee

Managram 2,000 mana:

Is this a game? An art piece? A psychological experiment?

Yes.


I am offering bootleg account activations. Only 20 mana each. Please don't ask any questions. All sales are final.

@retr0id lol. time for me to open up burpsuite and see how you did that... I thought my RLS was decent

@retr0id oke I think I fixed the security. Try refreshing and attacking it again. Sending you a mana tip for bug bounty.

@Bandors Seems unfixed still

@retr0id had old RLS, try now...

@Bandors still unfixed

@retr0id give me 15 minutes I am doing a better check

@Bandors may I ask if this was vibecoded? the auth system unfortunately seems completely broken, I don't think this is something you can fix in 15 minutes

@retr0id It just had old RLS. It should be fixed now. I don't think you can mark things as paid anymore.

@Bandors nvm lol give me the full 15

@Bandors I have to sleep now, but good luck with the rest of the 15 mins ;)

@retr0id I think it's fixed. Tested security, moved has_paid to a different table, did some basic pentesting on it myself, I think it's good...

@Bandors Seems good on the has_paid front now. But there's nothing stopping me from updating another user's position without auth.

@retr0id are you sure? I'll double check, but try raising another player up in the air so I can confirm?

@Bandors okok yeah I am fixing it

@retr0id Stuff like this is why I am having registration window for a week, should be enough time to find problems before the experiment officially starts.

@bagelfan @nikki @retr0id

Account marked as paid. Welcome to the experiment.

⚠️Trade offer⚠️

You receive: 60 mana (instead of 2000 mana)

I receive: (60/2000)*100 = 3% of the prize if I win (rather than 100%)

@TheAllMemeingEye I would offer you 1940 mana in exchange for 97% of the prize if you win, but I think a buy-in of only 60 mana is not enough to motivate you to win

@retr0id a very intriguing offer! I suppose it could work like us pooling the mana for the ticket and dividing the winnings accordingly, with me playing on our collective behalf. I'm mainly proposing 60 mana because that's approximately the most I emotively feel comfortable having a high probability of losing.

@TheAllMemeingEye It is a +EV proposition for the both of us if we think you have a higher-than-average chance of winning vs the other contestants. And I think that's unlikely if you have less at stake vs other contestants - but I could be convinced otherwise!

(edited)

@retr0id hmmm, I have pretty long streaks on here and Duolingo

but at the same time I don't have much experience with puzzle games.

Would you be open to being the player instead under a similar-ish mana split? (not sure if it benefits you for me to be contributing/taking more or less)

If you get stuck on a puzzle you can message me and I'll try to help you solve it at some point that day.

(edited)

@TheAllMemeingEye OOH, my duolingo is 441

@TheAllMemeingEye could you be convinced to go up to M100? If you were and @retr0id were also interested, I'd be happy to go halves in helping sponsor your run

I.e. an entry fee split of 100:950:950 (and proportionate winnings split)

Also open to other proposals (and ofc you're also more than welcome to ignore my proposal)

@Nat would you also be willing to help brainstorm puzzle solutions if I get stuck?

@TheAllMemeingEye Trade request denied, lol. People need to have skin in the game.

@Bandors is the later proposal for achieving a similar end via pooling the cost with other users also forbidden?

@TheAllMemeingEye Trying to keep it simple. 2k mana = one ticket, ticket given to the user who sends the mana. If you make a deal between each other, that's between you two.

@Bandors

People need to have skin in the game.

@TheAllMemeingEye can't guarantee I'd always be able to respond in a prompt enough manner to be helpful (most weekdays would be unavailable outside of roughly 02:00-10:00 UTC) but yeah if I'm free I'm absolutely happy to help (and I have been known to enjoy a good puzzle or two 😁)

"your account has not yet had a verified deposit" (but maybe you're doing it manually?)

@retr0id Yeah, I'm doing it manually. I see your payment, I'll activate you when I wakeup. Welcome to the experiment!

I'm in an Asian timezone so I need to head to bed. Four players so far, 16k mana prize pool :o
btw, thanks to @jim for a generous 10k donation to this prize pool!

Can I have a cheaper version? Like 500 mana please (i dont have mana)? please? :3

@121

>_>

then can i pay 1000 mana please :3 thanks!

@121 I'm gonna go broke if I cover everyone's entry fees. Other guy was a genuinely low balance new manifold user :v

The risk of losing 2k mana is what makes the experiment interesting...

@121 Thank you for joining the experiment. Account marked as paid, and prize pool will be updated.

Can we have a cheaper version? like 300 mana?

@100Anonymous I will personally cover your remaining 1,700 for the prize pool.

@Bandors Thank you so much!

@100Anonymous Managram me the 300 and then sign up, and I'll mark your account as paid and add the remaining 1700 to the prize pool.

@100Anonymous Account marked as paid. Cheers.
