Turn a landscape into a transport network
OpenTTD is an open-source reimplementation of Transport Tycoon Deluxe. You build roads, railways, docks and airports to connect towns and industries. The interesting problem is not simply buying a vehicle: it is making the route, stations and orders work together, then expanding without making the network harder to operate.
The official tutorial starts with buses before moving to trains and aircraft. That progression is useful for a first visit because the basic sequence—build the infrastructure, buy a vehicle and give it orders—carries into larger transport systems.

Free assets and a browser save bridge
This web build includes OpenGFX, OpenSFX and OpenMSX, so it does not require original Transport Tycoon data to begin. The host identifies the game as OpenTTD 15.3 and supports save import and export between browser and desktop play.
Online Content connects to OpenTTD's add-on service for items such as graphics, AIs and scenarios. That label describes downloadable content; it should not be read as a promise that this browser build offers multiplayer sessions. The host also links a separate iOS test build, which has its own experimental status.

Start with a small route you can inspect
Pause a new map and look for a simple opportunity. A bus route needs stops, a depot, a purchased bus and orders telling it which stops to visit. Build those pieces before unpausing, then watch the first journey. Seeing a vehicle complete its orders is a better foundation than laying out a huge network immediately.
Hover over toolbar buttons for their tooltips. Some menus open by holding the mouse button, moving to an option and releasing; knowing that interaction makes the dense interface easier to explore. Keep a starter save before experimenting with a larger network or add-ons, and export it if you want a copy outside browser storage.
