Google Play Games
Free Google app that syncs your game library and progress to Windows PC
This page lists 13 Windows games and game clients that cost nothing to download. Before installing any of them, check size, update date, licence and ad behaviour. The size gap is large. Minecraft Launcher is 2.1 MB, while 0 A.D. is 1541.8 MB, so look at free disk space and your connection first.
No app on the list is marked ad-free. None is tier A either; every title shown here is tier B. That is a limit of what the ratings cover, not a verdict on the games.
Licences differ too. OpenTTD uses GPL-2.0 and OpenRCT2 uses GPL-3.0, both open source. Roblox Player falls under the Roblox Terms of Use, and the Riot Games titles are proprietary. Wherever possible, download from the developer's own source.

Minecraft Launcher from Mojang is the smallest download on this list at 2.1 MB. The current version is 2.0.0.0, last updated October 4, 2025. It is the official launcher for the sandbox voxel game, with a proprietary licence, and it is free. Check ad behaviour yourself.
0 A.D. from Wildfire Games is a historical real-time strategy game still in development, at version 0.28.0, updated February 23, 2026. The download is 1541.8 MB, by far the largest here, so plan your disk space. The licence is GPLv2 and the game is free.
OpenTTD 15.3 is a transport simulation modelled on Transport Tycoon Deluxe, updated April 5, 2026. At 8.5 MB it is light, and the GPL-2.0 licence keeps the source open to inspect. The licence alone does not settle whether it shows ads.
OpenRCT2 0.5.7 re-implements RollerCoaster Tycoon 2, a park management simulation. It was updated November 1, 2026, the latest date among these picks. The size is 74.1 MB under GPL-3.0. Read the project page before installing to see whether original game files are needed.
Roblox Player 0.745 is a 13.2 MB client, updated October 26, 2026. Roblox Corporation licenses it under its Terms of Use rather than an open licence, so those terms are worth reading. Content varies, so judge in-app content when you run it.
No app in this group is flagged as ad-free, so treat ad behaviour as unknown and check the developer's page or the installer before you proceed.
OpenTTD (GPL-2.0), 0 A.D. (GPLv2), FlightGear (GNU GPLv2 or later), Stockfish (GPL-3.0) and OpenRCT2 (GPL-3.0). Minecraft Launcher, Roblox Player and the two Riot Games titles are proprietary.
Downloads range from 2.1 MB for Minecraft Launcher to 1541.8 MB for 0 A.D. League of Legends (North America server) is 73.2 MB and VALORANT (North America server) is 72.5 MB. Those are the package sizes, and they do not include anything a game downloads afterwards.
Compare update dates before choosing. Google Play Games, version 157.0.8089.0, was updated July 2, 2026, and Stockfish 19.0 on September 5, 2026. Minecraft Launcher's last listed update is October 4, 2025, the oldest date among the titles named here. An older date is not a fault, but it tells you how current the build is. Stay with official downloads and avoid third-party sites that repackage installers, since the license and the file you receive may not match what is listed here.
