Each season, there is a Season Pass with many levels of rewards. Completing Daily Limited Time Quests will award pass points, which are used to level up the pass and get rewards.

A Premium Season Pass is an upgraded version of the Season Pass and is an in-app purchase that can be made by tapping Season Pass button in the Menu. The Premium Season Pass provides a bonus to ooze production, scrap production, and Adventure battle rewards."[1]
