From the back of the box (translated):
"Build the most powerful themepark that you've ever seen. In Pretpark Tycoon you stand at the helm of your own amusement park. Build 3D attractions and attract many visitors. Groups of people walk through your park. If they visit your attraction, you earn fun chips. The player who earns most fun chips, wins the game. Pretpark Tycoon. The ride of your life!"
Pretpark Tycoon is a Monopoly-like/Hotels-like simplified children's game. Players buy and expand attractions with in-game money. Money is earned via Chance-cards or by exchanging fun chips for money. Fun chips are collected when visitors stop at your attraction. The first player to collect a certain number of fun chips, wins.
Players have no personal token on the gameboard. Four visitor group tokens move in one direction in the park. After your 'dice roll' (with a spinner) you decide which of the visitor groups you will move to reach your goal:
to a spot where you can buy or expand an attractions,
to a spot with an attraction you own to earn fun chips,
to a spot where you get a Chance-card,
or simply to a spot to pass the attraction of the other players so they won't collect fun chips.
