Building with play.fun

play.fun is the fastest way to launch, distribute, and monetize games - without middlemen.

play.fun is a platform where every game gets its own tradable token - a playcoin. When people trade your game's playcoin, you earn directly from the trading fees. No app stores, no middlemen, no 30% cut. Integration takes minutes.

The Problem

As a game dev today, your options suck:

  • Submit to app stores → lose 30% on every transaction

  • Pay for your own marketing → no guarantee of players

  • Hard to reach real users without burning budget

  • Platform takes the upside - not you

What play.fun gives you

play.fun flips the model:

  • Free distribution to millions of players

  • Earn from trading volume - every trade of your game's playcoin generates fees that go directly to you

  • Plug-and-play SDK to integrate in minutes

  • Your own token - each game gets its own playcoin on Solana, tradable and spendable on the game

How Developers earn

  1. Your game gets a playcoin - a Solana token launched specifically for your game

  2. Players trade your playcoin on the bonding curve (and on DEX after graduation)

  3. Every trade charges a fee - you earn directly from those trading fees

  4. More players and more trading volume = more earnings for you

  5. Earnings are in SOL, claimable from your on-chain fee position

Your revenue scales with your game's popularity. Build a great game, attract players, and the trading activity around your playcoin becomes your revenue stream.

Why it works

  • Players are already here, earning playcoins by playing

  • Games are ranked and surfaced by player engagement

  • Each game has its own tradable playcoin on Solana

  • Devs earn directly from trading volume - not from a middleman cutting you a check

  • No corp gatekeeping, no 30% cut, no BS

hashtag
What you can do

  • Submit any game - even small AI-built ones or MVPs

  • Launch a playcoin for your game

  • Earn by building. Grow by default. Own your upside.

Build with AI Agents

The fastest way to build and ship a game on play.fun is with Game Creator - an agent skill that turns AI coding assistants into full game studios. One command handles scaffolding, design, audio, deployment, and play.fun SDK integration.

Install the agent skill:

Then just tell your agent:

The agent will scaffold a Phaser 3 or Three.js game, add procedural audio, polish the visuals, integrate the play.fun SDK for leaderboards and rewards, and deploy - all in one workflow.

What it includes:

  • 9 skills, 8 commands, and 4 autonomous agents

  • Phaser 3 (2D) and Three.js (3D) game engines

  • Procedural audio generation (no audio files needed)

  • Automated Playwright testing with visual QA

  • One-click deploy to GitHub Pages or Vercel

  • Built-in play.fun SDK monetization

Manual Integration

Already have a game? Here's how to integrate the play.fun SDK directly:

Step 1: Build your JavaScript game

Use any AI tool (Claude, ChatGPT, Cursor, etc.) to build your HTML/JavaScript game.

Step 2: Prompt the AI to integrate play.fun

Add the play.fun SDK Implementation Guide to your project and give your AI assistant this prompt:

Read the play.fun SDK Implementation Guide and integrate the play.fun SDK into my game. Save points when [describe when points should be saved - e.g., "the player dies", "a level is completed", "the game ends"].

The agent should:

  • Add the SDK script and API key meta tag

  • Initialize the SDK with the points widget

  • Call addPoints() during gameplay

  • Call endGame() when the round ends (this opens a blocking modal, so only call at end of session)

That's it! The SDK handles authentication automatically when ending the game.
