Roller Coaster Tycoon 3 Cheat Codes


To Use These Codes Change a peep's name to the code (with spaces and caps) Then click out of the peep control.

Animals Constantly Breed - Should make your animals reproduce very quickly, like rabbits.

Alvin Swazonegger
Allow Large Billboard Movies

Mornington Crescent
This allows building shops etc. underground (use SHIFT to lower an object's position until it is say, level with an underground path).

David Walsh
This allows removal of the user interface (ie all the icons, menus etc) using CTRL+U once the cheat is active. This is great for taking screen shots. Press CTRL+U again to get the user interface back.

M Brookes
Enables you can place wall pieces and other scenery items on the edge of path tiles.

Alistair Lindsay
Alters the speed at which some sound effects are played at pause, fast and fastest.

Rick Griffiths
Changes the inside of a tunnel from rubble to sharks on both sides, the ceiling and the floor.

Andrew Thomas
Decreases track friction, which can make coasters go faster along their tracks

David Braben
Disable the Lift Chain Speed & Launch Speed limits. Normally, you are not permitted over a set speed limit. Usage: Select a coaster. Select "Operating Mode". You must have "Powered Launch" selected to alter the Launch Speed.

Andrew Gillett
Unknown effect. (On the first Career mission, this code will double the value rating of your park - which will complete your first mission objective) (On other tested missions, it seems to possibly cause a slight increase in park value too)

John D Rockefeller
Increase your money by ,000

Chris Sawyer
Cheer (Lp) - All guests applaud you & jump into the air

All guests stand around looking down at the ground (are they looking for mice between their feet?)

Guido Fawkes
Enables the "Advanced firework editor". Usage: Scenery -> Firework Mixmaster -> Fireworks Displays -> Add firework display -> Advanced firework editor

Cheer (Fade) - All guests applaud you

James Hunt
You are given a buggy vehicle to ride in - exit coastercam and delete as scenery when done

D Lean
Open the "Flying Camera" routes editor (also available through Ctrl + Shift + 0 without using cheat)

A Hitchcock
Hitchcock - not sure what this does (could be related to the birds like Alfred's movie)


Every Person (both guests & staff) move super fast, though the game time passes at normal speed (rides & coasters do not speed up) (Expires after 20 seconds)

Make Me Sick
All guests become Sick and vomit immediately

Jonny Watts
PeepCam (see the world through the eyes of the guest who you just renamed)

John Wardley
Coaster Heights (ride & coaster tracks can be built without height limitations)

Unbreakable (Buildings/Rides/Coasters do not break down any longer)

Jon Roach

Sam Denney
Ride All Coasters (make all guests ride every park coaster before leaving the park) OR it may just make guests ignore their nausea rating
