Play Heroes III, RollerCoaster Tycoon 2 and Transport Tycoon on Android (2026)

Three classic PC games now run on Android through open-source projects that rebuilt their engines: VCMI for Heroes of Might and Magic III, OpenRCT2 for RollerCoaster Tycoon 2, and OpenTTD for Transport Tycoon Deluxe. They differ in one important way: two of them need files from the original game, which you have to own, and one doesn’t. This site hosts only the open-source apps, never the original games’ files.

What you need

• VCMI needs the original Heroes III, the Shadow of Death or Complete edition. Its Android guide recommends GOG’s offline installer: you select the .exe and the .bin inside the app and it imports the data. The 2015 HD Edition doesn’t work.
• OpenRCT2 needs the desktop RollerCoaster Tycoon 2 or RCT Classic (GOG, Steam or CD-ROM), not the mobile RCT Classic apps. You copy its Data and ObjData folders into a folder called rct2 on the phone yourself; the guide warns the first start may crash once or twice.
• OpenTTD needs nothing else: the APK includes free replacement graphics, sound effects and music, so it is ready to play as installed.

At a glance

How finished each one is on a phone

• VCMI has its own Android guide and a Google Play version. It plays in landscape with haptic feedback, has basic controller support, accepts a mouse, and offers mods (including Horn of the Abyss) in its launcher.
• OpenRCT2 works, but its own guide says the interface and controls are “not optimized for phones”: a tap is a left click and a double tap a right click.
• OpenTTD on Android is a community port, based on a version from 2024; the official project has moved on to 15.3. The port adds a vertical toolbar, adjustable button size and confirmations for building, but multiplayer only works with servers on the same old version.

Updates and signatures

Each file can only be updated by a file signed with the same key. VCMI and OpenTTD here are F-Droid’s builds, so they can’t update, or be updated by, the projects’ own APKs or Google Play versions. OpenRCT2 is the project’s own APK and isn’t on Google Play; it checks GitHub for new releases at most once a day. Before switching between versions of any of them, back up your saves.
