RollerCoaster Tycoon is an isometric amusement park building game released in March 1999 by Chris Sawyer.

The game started development in September 1996, running on an evolution of the Transport Tycoon Deluxe engine, under the name White Knuckle. [1] The code was written by Chris Sawyer himself in assembly language[2] with just a small portion of the code interfacing to Windows and DirectX written by Fish UK[3]. The visuals were created by Simon Foster, while the theme music was composed by Allister Brimble.

The game's first expansion from November 1999 had two titles for different markets: Corkscrew Follies in North America and Added Attractions internationally. Aside from new scenarios (one being the first real-world park replica, Alton Towers) and rides, it added gameplay changes like signs that can be used as path blockers for all non-staff and the option to give guests "real" names. The second expansion from September 2000, Loopy Landscapes, added further new rides and scenarios, along with the option for all rides to play a selection of new music tracks by Allister Brimble or one of two custom music slots filled by the user's music files. The latest (1.20.013) patch for Loopy Landscapes would add native Windows 2000 support, and by transition the Windows NT line of operating systems as a whole; reprints of the expansion would include this patch by default. The base game and expansion would be combined in the Gold Edition (North America) / Totally RollerCoaster, with the 2003 North American variant Deluxe Edition including a unique executable version (1.20.015) with which common trainers do not work, as well as a selection of user-created ride tracks from the Ride Exchange section of the official website at the time. This version would be the one released on digital stores in the early 2010s.

The game was replaced by its 2002 sequel as the community favorite due to its expanded theming and construction controls, which in turn was replaced by the community open-source rewrite OpenRCT2. RollerCoaster Tycoon content can be imported to OpenRCT2, but the latter still requires the sequel as its base to run.

The fully patched version of the game runs on all Windows systems, but traps the mouse input even after the process is closed, requiring repeated right-clicking in empty space to free the left mouse button.

Version differences

The Gold Edition (known also as Totally RollerCoaster in Europe) includes the base game and both expansion packs.
The Deluxe Edition is a variant of the Gold Edition that comes with a unique executable (1.20.015 as opposed to patched Loopy Landscapes' 1.20.013) that is more resilient to common trainers. It also comes bundled with many custom track designs from the old official website's ride exchange section. It was originally only released in North America, but digital releases are based off this version.


A free demo version is available from GameFront.
It includes three scenarios: Forest Frontiers, Diamond Heights, Evergreen Gardens.
It allows for only several minutes of gameplay at a time, without a save/load function.


Type Notes
Expansion pack The expansion packs include new scenarios, scenery, rides and quality-of-life improvements.

Essential improvements


The latest official patches for the base game (v1.08.187), Corkscrew Follies / Added Attractions (v1.10.026) and Loopy Landscapes (v1.20.013) are available from GameFront.

Downloadable content

There are two official roller coaster collection downloads from Chris Sawyer, both available via his website. While the "Cat" collection can be used in any version of the game, the "Phobia" collection can only be used in conjunction with games that have either the Corkscrew Follies/Added Attractions or Loopy Landscapes expansion packs.

Other official tracks from Chris Sawyer and John Wardley (including the two aforementioned ones), formerly available on the official website, are available from here (at the bottom of the page).

Also released were multiple downloadable scenarios, archived here.

Hack widescreen resolution[citation needed]
  1. Open rct.exe with a hex editor such as HxD
  2. Search for the following string: 58 02 00 00 68 20 03 00 00
  3. Depending on the chosen resolution, edit the string accordingly:
    1. 1280x720 (16:9): Change 58 02 to D0 02
    2. 1280x768 (15:9): Change 58 02 to 00 03
    3. 1280x1024 (5:4): Change 58 02 to 00 04
  4. Search for the string 20 03 00 00 c7 45 f4 58 02 00 00
  5. Change 20 03 to 00 05 (regardless of the screen resolution)
  6. Save and close the hex editor.
  7. Run the game, start/load a save, click the save icon, and click on "Options"
  8. Select the 800x600 resolution to enable the resolution that is hacked in.


Higher resolutions could result in decreased performance, especially if there is a lot of attractions on screen.

  1. Navigate to <path-to-game>, right click RCT.exe and go into Properties
  2. Open Compatibility tab and click on Change high DPI settings
  3. Enable Override high DPI scaling behavior and choose Application in dropdown menu

Issues unresolved

Mouse issues after closing

In Windows XP and above, after the game is closed, the left mouse button might seem unresponsive as it is still assigned to the game process. Repeatedly right-clicking (preferrably in an empty section of the desktop) will "release" full mouse control. On Windows 9x, this issue does not seem to appear as the game process leaves an "empty" tab in the taskbar that is closed by a single click.
