How to Make Tunnels in "Roller Coaster Tycoon"

Simulation game “Roller Coaster Tycoon” lets you design and operate your very own full-sized theme park. While much of the game simply involves plopping down pre-fabricated buildings and attractions, such as information booths, Ferris wheels and funhouses, you have a full range of customization options when it comes to designing your theme park’s roller coasters. You can lay down a nearly-endless series of tracks to create corkscrews, loop-de-loops and massive drops. Add tunnels to your roller coaster to leave your guests in the dark and add an extra bit of thrill.

Select the “New Ride” icon, and then select “Roller Coaster” and “Build This” to start building your own roller coaster.

Select the “Land” icon (a shovel digging into dirt) when you’ve reached the part of your track where you wish to place a tunnel.

Click a tile of land near your roller coaster. Move your mouse upward to raise the land upwards and create a hill. Continue this process until the hill is as long as you want your tunnel to be.

Click the “Track” icon to continue placing track. Place the track through the hill and it will automatically form a tunnel through the hill and come out the other end.
