Design flowing marble runs on a 2D grid.

Feedback

Build a marble run that is fun to watch.

Place parts on the grid, press Play, and share the exact same course with a single URL.

How it works

  1. Place a single Start and connect a working path to Goal.
  2. Use the part buttons to shape the course on the 20x12 grid.
  3. Press Play to stream red and blue marbles from the same Start.
  4. Copy the share URL to open the exact same course later.
