OpenTTD is a free simulation game released under Open Source (GPL-2.0). It runs on Windows, macOS, Linux, needs about 200 MB of disk space, and requires no account, payment or trial. On a computer, the fastest route is the PlayBound Launcher. On a phone or tablet, use the official store or site instead.
Choose how to install
Install with PlayBound or download from the official source without the launcher.
Install the PlayBound Launcher, then find OpenTTD and press Install. The launcher downloads the official release and unpacks it. This is the fastest route and it never uses third-party mirrors.
Alternatively, download OpenTTD directly from the official site at https://www.openttd.org. Always download from the official source — third-party mirrors of free games are a common malware vector.
Official releases are published on GitHub at github.com/OpenTTD/OpenTTD/releases. Pick the newest stable release matching your operating system.
OpenTTD is also on Steam and is free there. Open the store page and press Play Game to add it to your library.

Extract the downloaded archive anywhere you like — there is no installer, just a portable folder. If Windows SmartScreen warns about the .exe having an unrecognised publisher, that is normal for open-source projects without a paid code-signing certificate — choose More info, then Run anyway.
macOS
Open the downloaded .dmg and drag the app into Applications. On first launch macOS may refuse to open it as unidentified — right-click the app and choose Open to approve it once.
Linux
Check your distribution's package manager first, which is usually the easiest route. Otherwise download the AppImage from the official site, mark it executable and run it.
chmod +x *.AppImage && ./*.AppImageLaunch the game and look at the settings menu before your first session — resolution and control defaults are worth checking. OpenTTD needs roughly 200 MB of free disk space.

Yes, entirely. OpenTTD is open-source under GPL-2.0 with no purchases, subscriptions or advertising. The free base graphics set means you no longer need the original Transport Tycoon Deluxe files.
No. OpenTTD ships with its own free graphics, sound and music sets, so it is a complete standalone game. You can use the original files if you own them, but it is not required.
Yes. OpenTTD has been in continuous development since 2004 and continues to receive regular releases, making it one of the longest continuously maintained games in existence.
BaNaNaS is the official in-game content service. It lets you download vehicle sets, industry chains, AI opponents, scenarios, heightmaps and graphics replacements directly inside the game, from a very large community library.
Yes. OpenTTD supports up to 255 players. You can join a public community server from the PlayBound server browser, have PlayBound start a dedicated server for your group, and host a game on your own PC. PlayBound Connect handles the setup: start a party with your friends, pick how you want to play, and everyone launches into the same game from the PlayBound launcher, with the dedicated server started for you if you choose one. It also supports LAN play. There is no subscription and no paid multiplayer tier.
OpenTTD is about transport networks between existing towns; Cities: Skylines is about designing and zoning a city itself. If you enjoy the traffic and logistics part of Skylines most, OpenTTD goes far deeper on exactly that.
