OpenTTD

Build a transport empire. Connect towns with trains, roads, ships, and aircraft.

OpenTTD gameplay

A classic, rebuilt

Lay a railway, schedule trains, and grow a transport network over decades. This build uses community replacement graphics and music, so no Transport Tycoon Deluxe files are needed. Start with a small map while learning the interface.

What you need

No original game files needed.

Controls & input

  • Mouse — build and manage
  • Right drag — move the map
  • Mouse wheel — zoom

Saving your progress

Use the in-game Save menu, then export a backup from the player toolbar.

Browser data can be cleared by your browser or operating system. Export a backup from the player before clearing site data or moving devices. Private browsing may not retain saves.

Known limitations

  • Large maps require more memory.
  • Network multiplayer is not provided by this site.
  • Music synthesis is not enabled in the current browser build.

Source & assets

The engine and game data have separate licenses. A source release does not automatically make the original artwork, music, or levels freely redistributable.
