Good news for anyone who misses old-school tycoon games, chaotic theme parks, and guests who will happily pay $12 for a bathroom if you place it in exactly the wrong spot.
RollerCoaster Tycoon 3: Complete Edition is free on the Epic Games Store from June 25 to July 2, 2026. Once you claim it during the giveaway period, it stays in your Epic Games library.

This is the classic 3D entry in the RollerCoaster Tycoon series, bundled with the Soaked! and Wild! expansions. That means you get the base theme park management game plus water parks, pools, animal attractions, safari-style content, and many more ways to accidentally create a lawsuit simulator with cotton candy stands.
You build rides, design roller coasters, manage prices, hire staff, decorate the park, keep guests happy, and pretend that launching a coaster directly into the ground was “part of the creative process.” The Complete Edition is still very much an older game, but that is also part of the charm. It has that classic tycoon loop where you start by carefully planning a beautiful park and end three hours later with a cursed spaghetti coaster called “Profit Machine 4.”
The Epic page lists the game for Windows, with modest system requirements, so it should run on a lot of PCs without needing a monster setup.
