OpenTTD

How to play

1. Connect towns and industries with transport routes that move passengers or cargo to their destinations.
2. Buy vehicles, assign them to useful routes and maintain a network that can earn more than it costs.
3. There is no short fixed round. Build at your own pace; the linked host manages browser saves and optional online content.

Make your move

• Mouse: use the game menus, map and build tools shown in the browser version.
• Keyboard: the build may expose OpenTTD shortcuts; check its in-game help for the current mapping.
• This is a third-party browser host. Its download, save and online-content behavior is managed outside Denny Games.

A small head start

• Start with a simple route between a nearby industry and the town that needs its cargo.
• Check vehicle orders and running costs before extending a line.
• Use the host's save controls if you want to keep or move a browser save.

Compatibility notes

This is an independent browser host, not the official OpenTTD website. The host controls its browser build, online content and save import/export; Denny Games has not audited which basesets it supplies. OpenTTD's official guidance distinguishes free Open* basesets from original Transport Tycoon Deluxe data, so do not assume the host includes rights to commercial data.

Denny Games has not verified this external build's gameplay, browser compatibility, controls or save behavior. Check the host's current requirements.

Play style: Point and move. This game runs on an independent host or browser build. Denny Games does not manage its account, session or saves; see the notes above for how this build handles them.
