Roller Coaster Tycoon Cheats

Cheap Coaster:
To make a popular, money making coaster for around $2,000 dollors, listen to this. Choose the steel mini coaster, not the steel looping coaster. Build the coaster until it says too high for supports. Then make a steep drop all the way down. Then, brakes at 9MPH, and make 2 small curves to end it. Make a big waiting line. This will get you lots of money, higher your park raiting, and all for a small amount of money.

User Cheat by nigel_10

Unlock Mega Park:
Finish all levels to unlock the Mega Park.

Prevent guests from getting sick:
Hold one of the mouse buttons and the ride will slow down, preventing guests from getting sick.
 

Get More guests:
Click on the "Park info" icon and set the admission fee to $20.00. Then, go to "Financial Information", click on "Advertisements" and start a marketing campaign for free park entry for four weeks. Watch your guest rates, however results may vary.
 

Keeping guests happy:
A clean park is a happy park.

Clapping guests:
Before you complete a mission go to a location that has a lot of guests. When the mission is over they will all start to clap.
 

Build underground:
Raise or lower land with the shovel. Then, go to the eye at the top of the screen. You should be able to see and build underground.

Keep ride's popularity:
To keep a scary ride's popularity, delete a segment of track and replace it with the same item. The guests will be fooled into thinking that the ride has been improved and will continue going to it.

See through bathrooms:
Build a bathroom and when someone enters click on the eye on top and choose "See Though Rides".

Build on high places:
When the message "Too high for supports" appears, just raise the land where you want to build.

Better shop and stall placement:
Put shops and stalls near the rear of the park, not at the entrance. Once tired and hungry guests have walked all the way to the back, they will be more than willing to pay higher prices for snacks.

Park Information:
If you click on the fence you will return to the entrance with the Park Information.

Easy Money:
CLick on the raise or lower land button and make the land high and low and high and low again and keep doing this until you run out of money then after a while you will have unlimited money and all of the parks will be unlocked and you can go to the mega park!

Build a cheap ride and make a huge queing line. make the ride free-.20 until it fills up. then, change the fee to $10-$20. everyone in line will have to pay since they cant get out of line (unless they don't have enough money)
User Cheat by brnxbombers  

Faster research:
Go to research and look under funding. There will be a lot of items check-marked, such as Shop and Stalls, Roller Coasters, etc. Go to maximum funding and choose only one item to check-mark to get faster research.
 

Display the date:
Move the pointer to where the month is shown, above the weather. Hold the mouse there until the date appears.
 

Balloon display:
If you accomplish the mission on the level that you are on, and if you have a balloon stall, when your guests clap they will all drop their balloons and have to buy another one.
 

Pop balloons:
When someone releases a balloon, click on it to pop it.
 

Sell lots of balloons at a really low price. When you complete the mission you can pop a large number of balloons.
 

Cleaning paths:
Simply place a new pathway over a dirty path to quickly clean it.
 

To quickly clean your park without using more money to replace the path that is dirty, select one of your handymen. Even though it might not be as fast as just replacing the path, drop them wherever there are empty cans and vomit piles. This also works for emptying the garbage.
 

Increase park rating:
Set your research to just roller coasters until you receive a steel or inverted steel coaster. Build a lot of power launched mode roller coasters( such as the Shuttle Loop). This should increase your park rating and guest numbers.
 

If you set the advertisements all at four weeks your money, park rating, and guests will all increase.

Make a real good park:
put lots of  short go karts and lots of shuttle loop steel roller coasters put the steel shuttle loop at $1.50 - $2
and put the go karts at $1 - $1.70 depending on how long the go kart track is.

Lots of Ride Passengers:
To get alot of people to go on a ride put the charge to .20cents. I did this with a merry-go-round. Next make sure you use a queing line (the blue one) and make it really long. Your guests will flock to the ride and fill up your queing line.
User Cheat by shockmaster28

Keep Guests in Park:
Make a massively long line for some popular ride. Then lower the price to $0.20 and wait until the whole line is full (something like 100 guests). Then wait until the ride breaks down and do not hire any mechanics afterwards. This will keep the guests standing in line forever. hahaha.
User Cheat by STAsnowman08

Happy Therapy:
If you want happy guests, build a small island surrounded by water or with a fence. Build a bathroom, drink stall and food stall. (Overprice them all for extra money) Then place like 3 entertainers there. Roam around the park looking for angry guests and carry them to the island. Drop them there and forget about them for some (game, not real) days. Rescue them later and put them on firm land, but only if the have a wide smile on their faces. Ta DA! Instant Happiness.
P.S. If after a month, they\'re unhappy, drown them... it relieves stress.

Go-Karts:
Yeah, this is useful. When you get the go karts as a ride build a custom go kart, then build the track like so: click on a wide land area and do the following, station platform(x4), right turn(x2),up track, straight track, down track, left turn(x2). open the ride at 3 bucks and put the number of laps at 10 and this will make the excitement rating soar for such a tiny ride. low cost easy to build and will never be unpopular, this little giant is the ultimate ride.
