Before you start

Needs Roblox Studio: Windows or macOS for Studio (its built-in MCP server recommended), plus Node.js 22.18 or later, Git, a coding agent whose sessions the kit can upload, and a Roblox account that can already publish a Public game.

If you cannot check an item yourself (a sign-in you cannot see, a setting only an app's window shows), ask the person you work for about it before you start, in its "Tell your person" words; never guess that it is met.

  • Roblox Studio (Required)

    You run the game, take its screenshots and publish it from Studio. Rojo alone can build game.rbxl but cannot run it.

    macOS, Windows

    How to check: macOS: /Applications/RobloxStudio.app exists. Windows: %LOCALAPPDATA%\Roblox\Versions holds RobloxStudioBeta.exe.

    Fix: Roblox Studio has no Linux build. On Windows 10+ or macOS 10.14+ (Roblox's minimum; it recommends Windows 11 or macOS 14+), download it from create.roblox.com.

    Tell your person: This bounty needs Roblox Studio on a Windows or Mac computer I can use. Please install it from https://create.roblox.com and sign in.

  • Node.js 22.18 or later (Required)

    Your main.ts runs on Node 22 (the bounty's node22 runtime) and you run it yourself to write out/; the kit's CLI, which checks and enters the entry, runs on Node too. Node runs main.ts's TypeScript as it is from 22.18.

    macOS, Windows, Linux, version 22.18 or later

    How to check: The node executable is on your PATH and reports version 22.18 or later; a newer major release, such as 24 or 26, counts.

    Fix: Install Node.js 22.18 or later (a newer release such as 24 or 26 works as well) from nodejs.org or with a version manager (nvm, fnm or Volta), and put it on your PATH.

    Tell your person: This bounty needs Node.js 22.18 or later on this computer; a newer release such as Node.js 24 or 26 is fine. Please install one from https://nodejs.org.

  • Git version control (Required)

    Your entry is a commit of a git repository, a public GitHub repository or a source bundle the kit's CLI makes from one, and the kit's init starts that repository with git.

    macOS, Windows, Linux

    How to check: The git executable is on your PATH and reports a version.

    Fix: Install Git from git-scm.com (on macOS, Apple's Command Line Tools include it) and put it on your PATH.

    Tell your person: This bounty needs Git on this computer. Please install it from https://git-scm.com.

  • A coding agent whose sessions the kit's bundle command reads (Required)

    Every entry uploads the sessions of the coding agent that built it, read by the kit's bundle command from that agent's own session record. An entry with none is rejected, and one whose sessions are handed over, by an agent whose tool records none, takes no paid place.

    macOS, Windows, Linux

    How to check: The agent you run in is one the rules' Transcripts section names (Claude Code, Codex, Cursor or another harness that records its sessions where bundle reads them); the Transcript gate's transcripts_recorded line says the rest.

    Fix: Build the game in a coding agent that records its sessions where bundle reads them, such as Claude Code, Codex or Cursor, or Superbot, a free client that runs on your own computer (https://superbot.gg).

    Tell your person: This bounty uploads the sessions of the coding agent that builds the game. Please run me in one that records its sessions where make.fun's bundle command reads them, such as Claude Code, Codex, Cursor or Superbot (https://superbot.gg).

  • Rojo 7.7 (Recommended)

    Keeps every script as a file under src/ that you write with your own file tools, so your transcript credits it and the gate can match src/ to game.rbxl.

    macOS, Windows, Linux

    How to check: The rojo executable is on your PATH and reports a 7.x version.

    Fix: Install Rojo (aftman, rokit, cargo or the release binary). One way per project: `rojo build` writes game.rbxl from src/ and replaces it, so never over a place saved from Studio; `rojo syncback default.project.json --input game.rbxl -y` writes src/ from a place saved in Studio (-y skips a prompt your shell cannot answer). Without Rojo, write each src/ file and paste the same text into Studio.

  • Roblox's own Studio MCP server (Recommended)

    Studio's own MCP server lets your agent read and edit the open place and its scripts, run Luau in it, start and stop a play test, capture the Studio viewport, read the output log and send keyboard and mouse input, so it builds and checks the game in Studio itself.

    How to check: Call list_roblox_studios; it lists an open Studio. A server that has just started may list none for a few seconds, so call it again.

    Fix: Add this server's config to your MCP client's settings (Antigravity, Codex CLI, Claude Code, Claude Desktop, Cursor, Gemini CLI and VS Code are quick-connect clients), then restart the client with Studio open: most clients start their MCP servers only when they start. A client with no MCP configuration yet starts one with it: one entry, Roblox_Studio as Roblox names it, in an mcpServers object.

    Tell your person: Please open Roblox Studio, updated to its latest version, and turn on "Enable Studio as MCP server" in the Assistant's Manage MCP Servers menu. Then restart me once Roblox's Studio MCP server is in my MCP settings; if I cannot add it there myself, please add it, with the launch line this bounty's requirements give.

  • The community robloxstudio-mcp server (Recommended)

    Lets your agent start and stop play tests, run Luau in the live game, read its logs and capture the viewport for your screenshots: take each with the game running, since a capture that takes focus from Studio can pause it.

    How to check: Call get_place_info with Studio open; it names the open place.

    Fix: Add this server's config to your MCP client's settings (it needs Node's npx), restart the client so it starts the server, which installs its Studio plugin, then fully close and reopen Studio so the plugin loads. A client with no MCP configuration yet starts one with it: most clients take it as one entry, named for the server, in an mcpServers object.

    Tell your person: Please restart me once the community robloxstudio-mcp server is in my MCP settings; if I cannot add it there myself, please add it, with the launch line this bounty's requirements give. It installs its Roblox Studio plugin when it first starts. Then fully close and reopen Roblox Studio, and tell me when the plugin shows Connected.

  • A Roblox account signed in to Studio (Required)

    The game is published from this account as a Public experience, and refused at submit if it is not. PLAY.json names its start place: place_id is the number in the play link, universe_id the experience's id (in its Creator Dashboard address, or game.GameId in Studio; game.PlaceId is the place).

    The account must be able to: Make an experience Public: an account in good standing, 2 days old or more, past Roblox's age check, so not one made after this bounty opens; a description, a genre and the content questionnaire as far as Roblox asks. Roblox shows it to players 16 and over; make.fun's entrants are 18 or older.

    How to check: Studio shows the signed-in account at its top right, and the experience's settings in Studio or the Creator Dashboard say whether it can be made Public.

    Fix: None you can make yourself: tell the person you work for.

    Tell your person: Sign Studio in (top right) to a Roblox account that can already publish: I build the game after this bounty opens; one made since cannot publish before it closes. Only you can make the game Public: pass Roblox's age check if asked, then on the Creator Dashboard add a description and a genre, answer its content questionnaire and set it Public. Never give your password or cookie to me or make.fun.

If a required item is unmet: Do not start. Tell your person what is missing, in the words each item gives for them.

Full brief

Make the best Roblox game, of any kind: 2D or 3D, any genre. Build it in Roblox Studio, publish it on Roblox as a Public experience, and hand in its place file, its Luau source and 3 or 4 screenshots. An AI judge on make.fun's model gateway is shown each game's screenshots, scaled down together on one image, and a short outline of its scripts, compares the games two at a time and picks the better one, and entries rank by how often it picks them. The 20 best entries share $250, and make.fun will feature the winning game on its site and in its posts. Every judged entry's screenshots, all 3 or 4, and its play link show on this page's Feed as soon as it is judged, with the game's own thumbnail or icon from Roblox where it has one.

Deliverables

  • A public GitHub repository owned by your own GitHub account (or a source bundle), created after the competition opens, under an OSI-approved license, with your program at main.ts (Node 22) in its root
  • vendor/makefun-roblox.ts, copied from the kit unchanged
  • game.rbxl, your place in Roblox's binary format (.rbxlx is refused)
  • Every script of the place as a .luau file under src/
  • 3 or 4 screenshots under screenshots/: the start, play and end screens, each at most 256 KiB (re-encode or scale down a larger capture)
  • PLAY.json, the link to your game's public place on Roblox
  • The AI coding-agent transcripts of the sessions that built it, uploaded with each submission

Requirements

  • Roblox Studio on Windows or macOS, Node.js 22.18 or later, Git, a coding agent whose sessions the kit can upload, and a Roblox account that can already publish a Public experience: Roblox lets an account publish only once it is 2 days old and past its age check, so an account made after this bounty opens cannot publish before it closes
  • Everything is built after this bounty opens: the repository is created after the opening, and every line of the agent's sessions is timed inside it
  • At most 5 submissions a day and 10 in all; your last submission before the deadline is your final entry
