Released by Atari in 2004, Roller Coaster Tycoon 3 (RCT3) carries on the tradition of dropping the player on a plot of land with all of the tools necessary to create and manage a thriving theme park. Some of the more customizable features of RCT3 concern landscaping and geography. The RCT3 expansion pack, Soaked!, expands these options even more by allowing the player to create waterfalls of any size. While some players have trouble with this feature, creating a waterfall is easy as long as you understand a few terraforming principles.

Find a flat, empty plot of land near your park.

Select the "Raise Land" tool and ensure that the onscreen grid is at least 12 by 12 squares in size. Once you master this technique, you can make your waterfalls any size you like. For now, stick with the larger size so that you can clearly witness the game's waterfall functionality.

Raise the land to the desired height. The most impressive waterfalls are tall, so raise the land at least 15 squares. Downsize the onscreen grid by two squares, position it in the center of the raised land, click the "Lower Land" button and drop the land one square. You will have what looks like a tower of land with a raised edge, similar to a castle keep.

Upsize the onscreen grid by two squares and position it on the ground adjacent to the raised section so that the edges are touching.

Lower the land one or two squares. You can make this section deeper, but it isn't necessary and is therefore a waste of your precious dollars.

Click the "Waterfall" tool. Click once in the lowered section below the tower to fill it with water.

Click once more on the top of your land tower in the lowered region to fill it with water. The game will recognize that the adjacent bodies of water are separated only by one horizontal square and several vertical squares, causing the waterfall to appear, much to the joy of your park attendees.


When you're raising land, shy away from using the "Mesa" function. While some users have managed to get the waterfall function to work with mesas, the curved edges of the land form seem to confuse the game. Stick with the "Square" function to make things easier on yourself.
