What does Players mean?
Players is a popularity-based editorial proxy, not live online players and not measured concurrency. Each entry uses its own recorded popularity evidence: observed GitHub stars or September 2026 Wikipedia pageviews for the original game. The two Q42 puzzles use their developer’s pageviews; projects for the same original game may share a value. We calculate round(sqrt(heat)); the result is neither active users nor unique players. Rounded GitHub displays are retained as observed. Sources and capture dates are available on each game’s detail page. Desktop is the default editorial recommendation when device support is unresolved; positive Mobile and Mobile + Desktop documentation is retained. No new physical-device gameplay test is implied.
Is OpenTTD for you?
Start with one useful route and expand it into a network; it offers longer-term planning instead of reflex-based combat.
What this browser project includes
OpenTTD is an open-source simulation based on Transport Tycoon Deluxe. Build routes between towns and industries, carry passengers or cargo, and expand a transport business. The linked community browser build lists save import and export, letting you keep a copy of a transport network you want to revisit.
Before you start
Game not loading? Use the safe troubleshooting guide before resetting anything.
Open the browser build and allow it to fetch its base graphics. If it reports Missing base graphics, reload after checking the connection; export important saves rather than relying only on local browser storage.
How to open this project
On the project site
Use Play to open the project’s own launcher in a new tab, then follow the visible start or data-import instructions. No gameplay completion is asserted.

- Freeciv-web — Choose turn-based civilization building instead of managing transport routes.
- Minecraft Classic — Choose a small creative-building session instead of a growing transport network.
