Project Description

Most on-chain games just random-ass coin flipping games with extreme speculation where your probability of winning is just based on pure luck

You don’t win because you’re creative or good at the game — you win because… randomness decided you should.

That gets boring pretty fast.

So we set out to fix this.

What if a game wasn’t about luck at all?

What if it tapped into something everyone naturally has — the ability to see, capture, and feel moments?

Humans are storytellers by instinct. You notice light, color, emotion, vibe. You don’t need training to spot a beautiful moment — your brain just knows.

That’s what makes png.fun special.

png.fun is the first daily social prediction game built on World where creativity and social intuition—not luck—decide who wins.

Here’s how it works:

A theme drops each day. You take a photo based on that theme — simple. The gallery opens, and the community backs the photos they believe will win. Odds shift. Momentum builds. A prize pool slowly forms.

When the day ends, the top-backed photo wins.

The creator gets 10% of the pool. The people who backed the creator share the rest.

It’s not random or passive. It’s a social market built on taste, instinct, and expressive skill.

png.fun isn’t just a game — it’s the first social prediction game built on the world app.

People won’t just play it. They’ll talk about it. They’ll share their wins. They’ll come back every day because every theme is fresh, every gallery feels fun, and every victory is "earned".

This is what games in crypto should feel like.

And it starts here.

May the best taste win.

How it's Made

png.fun was built as a miniapp on the World app for a few key reasons.

First, I love the World ecosystem and its miniapps. But most importantly:

Our game could easily be exploited by bots uploading AI-generated images, which would ruin the experience. We solved this using World ID to verify that every user is human. This simple step filters out sybils and ensures that every participant in our app is a real person, preserving the integrity of the game.

The World app has 4 million monthly active users, an enormous and engaged audience we can tap into. Unlike typical crypto spaces dominated by speculation, this user base consists of regular people who want to have fun and socialize, making it perfect for a creative, daily photo game.

With the combination of secure, human-verified participation with access to a massive, playful audience, png.fun is positioned to become a daily habit for users, creating engagement, virality, and fun that is difficult to achieve on other platforms.
