Coaster Rider is a fun simulator game whose aim is to create a rollercoaster like the Pegasus from the Europa Park in Germany. The idea is that the coaster can collect all the stars it finds in its path. In this mission you have to travel across floating islands, and for this you have to use powerful accelerators.
To build your rollercoaster you must take real factors into account, like gravity and friction. In each new scene the designs get more complicated, so you need to build with astuteness and intelligence.
Coaster Rider is a fun way to relax, and it`s free.
