Play

  • Mouse: left-click tools; right-drag the world; use the wheel to zoom.
  • Touch: tap to interact; use the Pan toggle for one-finger map dragging; pinch or use Zoom controls.
  • Keyboard: OpenTTD’s full shortcuts remain active while the canvas has focus. Escape closes game windows.
  • Save and load: use OpenTTD’s in-game menus. Saves and settings persist in this browser.

What is running

The simulation, map generation, economy, vehicles, routing, construction, game clock, windows, and save format are OpenTTD 15.3 compiled from C++ to WebAssembly. The browser host only prepares local files, presents the canvas, and adds platform controls.

Open assets and source

OpenGFX 8.0 supplies graphics and OpenSFX 1.0.3 supplies sound effects. Exact revisions, modifications, checksums, authors, licenses, and corresponding-source routes are recorded in the handoff.
