Making games
you already own

A plan for the tabletop ecosystem we're building: open-source games, modular engines, and a marketplace for the modders who'll fill it.

Open alpha · nukes.moddable.games team@moddable.games
▲ MODDABLE.GAMES 01 / 15
▲ Our mission 02 / 15

Publish moddable tabletop games — and turn players, artists and designers into co-creators.

An open-source ethos

Every rulebook is forkable. Every component is replaceable. Every variant is a pull request waiting to happen. Modders aren't a side channel — they're how the catalogue grows.

Why we're called Moddable

Not a publisher. Not a platform. A toolkit — modular game engines, a print-on-demand pipeline, and a marketplace — that turns the boards on your shelf into the boards you wanted them to be.

☢ NUKES

Territory. Attrition.
Nuclear brinkmanship.

A hex-tile board game where every token is a unit, a hostage, and a countdown timer — all at once. Plays on a board you already own.

AGE 12+
▲ THE INSTALLED-BASE PLAY

Nukes uses standard hex tiles — same size as Catan. 45 million homes already own half the board.

▲ Our vision for the future 04 / 15

Write rules.
Ship games.

The north star: a structured rulebook becomes a playable game automatically. AI agents research and write. A universal engine renders. The catalogue grows itself.

01 · RULES
Open-source rulebooks as structured data. Machine-readable, forkable, community-owned.
02 · ENGINE
One universal engine: chess, draughts, Go, and beyond. Bootstraps from schema.
03 · PLATFORM
Play online, embed anywhere, print on demand. Marketplace for mods and expansions.
04 · AGENTS
AI orchestration scales production. Research, build, and QA run autonomously.

Why now? The boards
are already on the shelves.

45M
Catan sets sold

Every one of them a hex board for Nukes — no new components required.

275M
Monopoly sets sold

500M people have played. Econopoly ships a fairer rulebook.

AI-callable
game engine

One universal engine ships as an MCP server. Any AI agent can start a game, query rules, roll an oracle, or render a board on our infrastructure with a single command.

UNIVERSAL PLAY API

Any game, one interface

  • ▲Start a game in any of 6 families
  • ▲Legal moves, apply, status, end conditions
  • ▲AI opponent across every family
  • ▲Board rendered to SVG or PNG
RULES + GALLERY

The whole catalogue, queryable

  • ▲Search 46 games, 296 variants, 511 rule pages
  • ▲117 piece sets and 334 boards as SVG
  • ▲1,726 puzzles with solutions
  • ▲Hex map generation, FOV, and pathfinding
ORACLES + GAME TOOLS

Tabletop RPG and session tools

  • ▲458 oracle tables across 10 RPG systems
  • ▲3,385 searchable entities for scene building
  • ▲TI4 drafting, Nukes combat, Colony odds
  • ▲Dice, decks, coins, and team splitters

Chess.com for every board game
ever imagined

The merge is done. One universal kernel where every game is a config file and no variant carries code of its own. 10 families, 204 playable variants, 6,527 tests. One platform.

SHIPPED

One engine, every family

  • ▲204 variants resolve to legal moves
  • ▲6,527 tests across 190 suites
  • ▲Consumer SDK, MCP server, REST API
  • ▲In production since 2025
HOW IT WORKS

A game is a config file

  • ▲Micro-kernel architecture: plugins compose freely
  • ▲5 topology types: grid, hex, track, pit, graph
  • ▲A game = config file. No hand-written code.
  • ▲Shared rules work across all families
10 GAME FAMILIES

Every classic covered

  • ▲Chess, Draughts, Go, Reversi, Shogi
  • ▲Xiangqi, Mancala, Morris, Hex strategy
  • ▲The Landlord's Game — the original Monopoly
  • ▲Any future family: add a plugin, not an engine
▲ THE ZERO-CODE THESIS

No code per game

Every game from standard chess to Endless Skies runs from a config file. Plugins compose topology, pieces, and rules. Ship a game by writing YAML.

Infinite catalogue

296 variants documented, 204 of them playable. When adding a game costs zero engineering, the catalogue compounds daily. AI agents write configs, not code.

Platform scale

One engine means one embed API, one SDK, one MCP server for every game. Third-party developers build once, reach every family.

First board game
engines with AI integration

No other tabletop platform offers AI-callable game engines. Ours are live, documented, and connecting to the fastest-growing developer ecosystem in history.

89
AI-CALLABLE TOOLS

Universal play, rules search, piece gallery, RPG oracles, game utilities across 8 namespaces, all callable by any MCP-compatible agent.

4
SURFACE AREAS

MCP protocol, REST API, OpenAPI spec, llms.txt. Every integration pattern covered from day one.

0
BUILD STEPS

Native ESM. Import our engines in browser, Node.js, or Cloudflare Workers — no bundler, no transpiler, no config.

9
EMBEDDABLE WIDGETS

Drop-in iframes for dice, decks, oracles, TI4, Nukes, and an API explorer. Auto-resize, themed to the host site, no build step.

▲ WHY THIS MATTERS FOR INVESTORS

Platform lock-in

Every AI agent that integrates our tools creates switching costs. Network effects compound with each new consumer.

First mover

No competing board game engine has MCP integration. We own this category before it has a name.

Revenue channel

API usage becomes a revenue line as third-party agents build on our engines at scale.

▲ How we scale 10 / 15

Write rules.
Get a playable game.

AI agents research, write, and build games autonomously. The rulebook is the source of truth; engines consume it directly. A small team ships at the pace of a large one.

01 · RESEARCH
AI finds rules

Agents scan patents, archives, and public domain sources. Verified content only.

02 · WRITE
Structured rulebook

Machine-readable markdown with frontmatter. Board topology, pieces, win conditions.

03 · BUILD
Engine generates

Config-driven board generation, movement primitives, and rule plugins bootstrap a playable game from schema. No hand-coding.

04 · PUBLISH
Live everywhere

Website auto-generates play pages. Embed via iframe. Print-ready PDF rulebook.

05 · GROW
Community forks

Open-source rules invite PRs. Every variant is a pull request. Catalogue compounds.

No developer
required

The frontmatter file is a contract, not a skill requirement. Everything a variant needs is a handful of declarations, so the authoring step can be a form, a chat, or an agent writing on someone's behalf. The engine cannot tell the difference.

01
WRITE

Describe the board, the pieces, and how you win. The fields are the game, and an agent can fill them in from a plain description.

02
PLAY

Playable the moment it validates, with legal move enforcement and an AI opponent. No build, no download, no waiting on an engineer.

03
SHARE

A link anyone can open, an iframe anyone can embed, and a print-ready PDF rulebook generated from the same file.

04
SELL

A mod is a file, so a marketplace listing is a file too. Designers keep the credit and the revenue; we handle hosting and fulfilment.

▲ NOBODY ELSE LETS A NON-DEVELOPER DO THIS

Board Game Arena publishes for you

Licensed titles, implemented by their engineers. You cannot add a game, let alone a variant of one.

Tabletopia and TTS hand you a table

You can move pieces around, but nothing enforces the rules. There is no game to share, only a session someone has to referee.

We make the rules executable

Write the rules down and they become a playable game with an opponent, a board, an API, and a rulebook. That is the whole product.

▲ MODDABLE.GAMES write it · play it · share it · sell it
▲ Competitive landscape 13 / 15

Why hasn't anyone
done this yet?

Existing platforms digitise board games. We're building the infrastructure for people to create and sell them.

BOARD GAME ARENA

Play licensed games online

Digital-only. Closed ecosystem. No modding, no creation tools, no physical bridge.

NO CREATION · NO PHYSICAL
TABLETOPIA

Sandbox simulator

Upload images, move them around. No rules enforcement, no AI, no print pipeline.

NO RULES ENGINE · NO BOTS
TABLETOP SIMULATOR

Physics sandbox on Steam

Fun but zero structure. No marketplace, no mobile, no web, no physical bridge.

MODDABLE.GAMES

Create, play, sell, print

Consumer SDKs, AI-orchestrated production, open-source rulebooks. 46 games shipped, 138 variants playable with AI. Embed anywhere.

AI PRODUCTION · OPEN SOURCE · EMBED API
▲ OUR MOAT — WHY THEY CAN'T CATCH US

Consumer SDK

Other games build on our engines. Dungeon Chess shipped on MCE — every new consumer deepens lock-in.

AI integration

89 MCP tools live across 8 namespaces. Every AI agent that connects deepens network effects. No competitor has this.

AI production

Agents research, write, and ship games autonomously. $30K in compute has produced 46 games and 296 variants — $652 per game.

Physical bridge

The only platform connecting digital play to physical production. BGA/TTS are screen-only.
