Where board games are written into being

Wyrd Builder turns a rulebook into a living, testable game — draw the board, ingest and validate the rules, forge every component, and watch a thousand simulated tables play it before your first print.

What’s new

Design intents: say what your game should do to players

You can now tell Game Designer what your game is meant to do to the people playing it, in your own words, and it checks your rules against that as you work. It never rewrites your rules to fit and never blocks you — it shows you where the game and the intent part ways.

Inside the builder

One spec. Four ways to shape it.

Everything reads and writes the same game specification — change the board, and the rules, components, and simulator already know.

01 · BOARD DESIGNER

Draw the world your game lives on

A full-screen canvas with real drawing tools — paint terrain, sketch non-playable areas freehand, and attach playable aspects like movement cost, line of sight, and setup zones to anything you draw.

  • Pen, polygon, and shape tools with tile-coverage awareness
  • Annotations bind to spatial zones the rules can address by name
Board designer: The full-screen board canvas — terrain-painted hex tiles, dashed annotation areas, the drawing tool rail, and the Design panel counting 82 tiles across 5 areas.
The board is a first-class part of the spec, not a picture beside it.

02 · RULEBOOK INGESTION

Your rulebook, read and challenged

Drop in a draft rulebook and Wyrd Builder parses it into structured rules — then validates them against the board and the components, surfacing contradictions, dead references, and unreachable states.

  • Clause-level extraction that links every rule back to its source text
  • Findings ranked by severity, each one fixable in place
Rulebook ingestion & validation: The ingest review dock, blocked on a closure violation, beside the validation report’s error, warning, and vocabulary-gap findings.
Every extracted rule keeps a thread back to the sentence it came from.

03 · COMPONENT EDITORS

Forge every piece of the game

Cards, factions, tokens, decks, tracks, and currencies each get a purpose-built editor — every field typed, every reference checked, every change versioned against the spec.

  • Contract-checked references between components
  • Versioned spec history with a visual diff for each revision
Component editors: The Structures editor — the spec’s section rail, the list of structures, and the typed detail form for the selected one.
One typed editor per primitive — no free-text spreadsheets.

04 · SIMULATOR

A thousand tables before the first one

Run automated playthroughs against the live spec — watch win-rate balance, game length, and choke points shift as you tune the rules, before a single human sits down.

  • Batch simulations with per-faction and per-seat balance reports
  • Replay any run turn-by-turn on the board
Simulator: The Simulate screen — seed, run count, per-seat factions and strategies, above the result of a finished run.
Balance you can measure while the design is still cheap to change.

The fates favor the prepared

The alpha is small by design — designers who join now shape what Wyrd Builder becomes.
