There are two ways to get to the 3rd park:

1. You can improve your progress in the park by adding some "pizazz" to it, like adding
your own roller coasters, stalls, rides, race tracks, and games.

2. You can go to any park and input the following code:

Square, Circle , Triangle, Square, Circle, Triangle, Square

When you have entered the code, you will hear a beep, and you have unlocked all of the
parks.
