What Is The Boolean Game?

Updated

The Boolean Game is a browser-based puzzle game for practicing boolean operations — union, subtract, intersect, and difference — the same shape-combining commands used in Adobe Illustrator, Sketch, Figma, and other vector editors. It is hosted at boolean.method.ac and is part of Method of Action. If you already work in a vector tool but still guess at which boolean operation to pick, this is a low-stakes way to build that instinct.

What you actually practice

Each stage gives you a target shape and a set of source shapes. You apply boolean operations to the sources until they match the target. The four operations the game drills are:

  • Union — merges shapes into one combined outline.
  • Subtract — removes the overlapping area of one shape from another.
  • Intersect — keeps only the region where shapes overlap.
  • Difference — keeps the non-overlapping parts, excluding the shared region.

These are the same four operations you find in the pathfinder or boolean groups of mainstream vector editors, so the mental model transfers directly.

Who it is for

The game suits:

  • Designers who use Figma, Sketch, or Illustrator but reach for boolean tools only occasionally.
  • Beginners learning how paths combine before they touch a real project file.
  • Anyone who wants to reason about shape math without setting up a document.

It is not a tutorial for a specific app's interface. It teaches the operations themselves, so you still need to learn where your editor hides them.

How to start

  1. Open boolean.method.ac in a browser.
  2. Read the target shape for the stage.
  3. Apply union, subtract, intersect, or difference to the source shapes until the result matches.
  4. Use Undo to step back and Start Over to reset the stage.
  5. Move to the next stage once the shape matches.

Settings worth knowing

The game exposes a few controls that affect how you play:

Setting What it does
Sound Toggles sound on or off
Animation speed Slider from 0.5× to 2×, slower to faster
Game data Reset to factory settings erases all data as if you had never played
Share stage Generates a link to a specific stage

The reset option is destructive — it clears your progress completely, so use it only when you want a clean slate.

Practical notes

  • The game runs in the browser, so there is nothing to install.
  • Progress and settings live in the game itself; the reset control confirms data is stored locally to your play session.
  • The site lists a Sponsor a Stage option and a Buy me a coffee link, which indicates the project is independently supported rather than sold as a product.

If your goal is to stop second-guessing which boolean operation to use in Figma or Illustrator, working through the stages here builds that recognition faster than reading about the operations in the abstract.
