RCT3: Wild! Cheats Top


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

Alvin Swazonegger

Allow Large Billboard Movies

RCT3: Soaked! Cheats Top

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.

v1a Beta Patch (for Original RCT3) Cheats Top

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)

Original RCT3 Cheats Top

John D Rockefeller

Increase your money by 1,000

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?)

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

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

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)

Make Me Sick

All guests become Sick and vomit immediately
