RCT-K

The original RollerCoaster Tycoon, on today's PCs.

RCT-K plays the 1999 game at any resolution from 640 x 480 to 7680 x 4320, sharp and pixel-perfect, with modern controls, multiplayer with your friends, mods, and new park systems you can switch on. In Classic mode it plays exactly like the original.

What RCT-K does

It hooks into your own copy of the game: the original program still runs the park, and everything RCT-K adds can be switched on or off. Saved parks stay the game's own files.

Any resolution

  • 640 x 480 up to 7680 x 4320: 4K, ultrawide, super-ultrawide and 8K.
  • Full screen, borderless, a resizable window, or one window across all your monitors.
  • Game size 1x to 4x, every pixel doubled and still sharp; the interface bigger on its own (125% to 400%).
  • Smooth motion between the game's frames, at your display's refresh rate.

Modern controls

  • The mouse wheel zooms towards the pointer; the middle button drags the view.
  • More zoom levels, W A S D or your own scroll keys, scrolling up to 4 times faster.
  • An Xbox-style controller plays the game, and a Steam Deck through Steam Input.
  • If the game ever crashes, a report is saved and the launcher offers to show it.

Park Race In testing

Everyone plays the same scenario at the same time, each in their own game, and the server keeps the score. Victory modes, teams and diplomacy, sabotage and world events, hidden stats, tournaments and monthly seasons. The CD release, GOG and Steam can race each other.

Open matches and results

Co-op parks In testing

Several players build one park together, each in their own game, kept in step by the server, with roles and permissions and an undo for admins. A server can keep a co-op park running while its players are away.

Spectating and replays

Watch another player's park live during a match, and replay every park of a finished match together. Snapshots, replays, park history, time-lapses and park photos for your own games.

Expanded mode

Every RCT-K park system at once: weather and seasons, a full calendar, staff careers and new staff, ride wear and maintenance, guest personalities and groups, crime and security, utilities, emergencies, construction crews and disasters. Sandbox adds larger maps and higher limits.

Mods and the creators

Mods bring new scenery, rides and scripts. Make your own with the Creator Studio (with its Sprite and Animation Studios), the Scenario Creator and its landscape generator, the Object Creator, the Ride Creator and the Behaviour Editor: rules without code.

The Workshop

Mods, ride blueprints and scenario objectives made by players, installed and updated in one click from the launcher. Uploads are checked for game files, so only original work is shared.

Dedicated servers

Run your own server on a PC or a rented Linux server, like the old games' dedicated servers: co-op parks, parks it keeps running, Park Race, an admin console. List it publicly if you like.
