Complete all other scenerios Unlock Mega Park
To retain a scary ride's popularity, simply delete a segment of track and replace it with the same thing. The guests will be fooled into thinking that the amusement has been improved and will continue flocking to it!
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.
Click on a construction button (like the leveling land button). Then click on a weed remove weeds without mowing the landscape
Find Guest #4321 and rename him "I Dont Like #s." After he is renamed, have him stay in the park for more than two hours. After that, you'll get an onslaught of guests (120-132).
Type one of the following as a guest name: (Warning! Many have been reported as Invalid.)
Michael Schumacher Faster go-carts (not as fast as Damon Hill cheat)
Katie Brayshaw Waving guests
Simon Foster Artist guest
Chris Sawyer Photographer guest
John Wardley Constantly Thinks Wow!
Melanie Warn Increase Guest Happiness
John Mace Pays double for rides
Damon Hill Goes extra fast on go karts
BigBucks makes the guest rich
Tony Day Eats lots of hamburgers
Mr Bean He will be a very slow go-kart rider and will be out of control.
If you are planning on demolishing a ride that's getting to old and nobody wants to ride it even for free:
then instead of just pushing the trash can to throw it away, click on the construction button then click on the bulldozer on the pop up screen. You don't get all the money back, but you do get some. Works especially well with rollercoasters, bulldozing one track piece at a time because you actually get all your money back
This game is listed twice. Each with different codes. So click on the other one for more.

Thanks to "Katrina" for sending in this hint:
To get past the fist scenario the best, go to the tutorial and after it is done making the roller coaster, take control. You will have tons of guests, and the value of your park will be over $3,000!
Thanks to "Aarron" for sending in this hint:
If you want more money this is how you do it when it starts to rain build a infomation kiosk and put the umbrallas for $10 pounds.
Thanks to "Benjamin Saville" for sending this one in:
To Drown a Guest. Select the level ground tool and delete a section of pathway.Then lower the ground one square.Select the "build footpaths tool" and build a footpath over that square. Keep selected and when a guest passes over it, delete that area of pathway,when the guest has fallen in,fill the square up with water.
Thanks to "e=mc2" for sending this in:
To drown a guest QUICKLY (this is faster than the other trick) first bring up their display by clicking on them, then click the claw tool and dunk them in some water!! >=) drown very angry guests, it will increase your park rating! :D
Thanks to everyone who helped with any of these:
When rides get stuck (In the message box it will say "Car/boat something hasn't returned to station yet") which mostly happens on boat hires or Wooden Crazy Rodent Roller Coasters, just pause the game, click on the the stuck ride, and double click the red light. The ride's boats/cars are now gone. Re-open the ride and then un-pause the game. The Cars/boats are no longer stuck and your line is still there (Although there is a mob like crowd of people, as you will notice once you colse the ride). Stuck Rides Hint
Buy a shuttle loop coaster and put it right near a path. Then delete the loop and the incline. After that you may want to put the speed up to 60 or higher. Then test the ride and watch it travel on the path. When the path ends, so does the guests lives. Road Train
Go and buid Boat Hire. Do not build any tracks. When people are on it raise the water so it turns into land. they will be floating on land. Hover Boats
If you are building a theme park, and you get the boat hire ride, then build a little pond so u can build it, (but DO NOT make tracks, just let them go their own way.) Then when all the boats are out of the station, you can take all the water away and the boats will be flying! You can also do it with canoes, swans, and rowing boats! Flying Boats
I figured how to put people in "Limbo Land". Say a guest is wanting to find the park exit, but you don't want him to, click on the guest and pick him up with the tweezers and close his box without putting him down. Limbo
If you have heard the familiar thought from your guests;"I want to go on something more thrilling than-"(whatever your ride is), then you must have some sort gentle ride no one wants to go on. But there is a way you can make your guests go on these rides. First, build a Whoa Belly or Gravitron-on the intense side. Then, Construct a Gentle ride like a slide, merry - go - round or ferris wheel next to it. Since your guests have come off intense puke machines, they will be more than happy to go on a more gentle ride. Useless Gentle Rides
First, start constructing a "Whoa Belly". When you have the choice of how many levels you want your ride, select only one pyramid top piece. Now, go to the ride screen and click the options icon (the one with the gears moving together). On the option screen, there is an option on how much of a boost you want on your ride. Go up to 90 mph. Now, test your creation with guests on it, and watch the guests fly into the sky with the ride car, and laugh as the ride explodes when the people land. Note: If you want to do this again, then demolish the old build building and create another using the same steps. Another (and rather entertaining) way to kill guests
You know you can use the visual icon(the eye of a person at the top of the screen). Now, we can put it into good use. First, build a bathroom. Now, open it and click the visual icon. Highlight the option reading "see-through rides" and if there are any people inside the bathroom, you will see them inside. Note: I'm going to try and actually see the people up close in the bathroom, by selecting a guest who is heading toward a bathroom and watching them go in. Hmmmmm... You're Never Alone
On the 'Thunder Looper' (steel rollercoaster) you can increase the launch speed when guests are on the the ride by increasing the launch speed, the rollercoaster will fly off the rails and crash killing any passengers on the ride. How to kill guests
Guest name a guest: BigBucks (for some reason it doesn't work on all games) Unlimited cash
If you have created a roller coaster with a high nasuea rating, then your guests will most likely be clutching their mouths and puking. To solve this problem, install food&drink stalls nearby. Another way is to put benches close to the exit. Remember, listen to what guests say of your park, and therefor, you can improve it! Sickly Helpful
Dig a hole and put footpaths in it. Put benches on the footpaths. Pick up a sick guest and drop them in the hole. They will recover very quickly. Don't forget to put the guest back ON A FOOTPATH or they will get VERY angry! Cure Nausea
There are two ways to make people lose their balloons: 1. Win the objective (this makes EVERYONE lose their balloons when they applaud you) 2. Drop a guest with a balloon in water. Make people lose balloons
Start with a large body of water in your park ( don't build it yourself! ) When you see a duck, click on it to make it quack. Duck Quack
Start any level and build a water tile and throw someone in it. It doesn't matter who. After he starts drowning remove the water. He will still keep drowning even if he is on land, as if he's in quick sand. QuickSand
Name a guest Coaster. Free rides
To get lots of money for your park, close it down for one full year! Afterwards, a man dressed in a blue suit and holding a clipboard will give you a little “helpful money” ($1,000,000). Receive A One Million Dollar Gift
To retain a scary ride’s popularity, simply delete a segment of track and replace it with the same thing. The guests will be fooled into thinking that the amusement has been improved and will continue flocking to it! Retain Ride Popularity
Though it is questionable ethically, it makes business sense... Maintain high park ratings by drowning all unhappy guests! (Click on a mad guest and use the pincer icon to place him in the water.) Increase Park Rating
Location is the key to maximizing profits! Here are a few business tips: Don’t squeeze stores together. They will compete for customers and their prices will fall. 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. Maximizing Productivity of Shops and Stalls
To remove weeds without mowing the landscape, click on a construction button (like the leveling land button). Then click on a weed it will disappear! Remove Weeds without Mowing
