How does Roller Coaster Tycoon come up with ride ratings?

I love to play Roller Coaster Tycoon. However, one thing about the game has puzzled me. When you finish building your roller coaster and click ‘test’, the game comes up with various ratings for Excitement, Intensity, and Nausea, each ranging from Low to Ultra-Extreme. How does the game come up with, and what factors go into, these ratings?


I never experimented enough to come up with anything approximating an exact formula, but this was the impression I got:

  1. Excitement is determined by the variation in the track. A simple circle will get you a low score, whereas a track with twists, drops, and loops will get you a high score.
  2. Intensity is determined by the speed / force (see Raven’s comment). If you start out high with a drop and add boosters, etc., you’ll get a higher score here.
  3. Nausea is similar to Excitement, I think it has to do with a large amount of variation in a short space. A booster right before a series of tight turns will probably get you a higher Nausea score, and spacing it out lower. If the total variation is the same for both versions, I would expect the Excitement score to be the same.
