Great Slides

A Great Slide is when you/your bird slides down a hill perfectly without bouncing or anything else that counts as an error.

How to get one
You can get a Great Slide by making no errors when sliding down a hill. It can be hard when you have just started the game, but it gets easier when you know more about the game. If you get 3 Great Slides in a row, you can get yourself into Fever Mode.
