Achievements reward you with different resources for completing long-term goals in the game, and help you track your progress as a player! A list of available Achievements can be viewed by tapping on the mission menu on the top right corner of your screen and viewing the "Achievements" section.
There are over 300 achievements that you can unlock. They are separated into 5 different categories:
These separations let you know where you need to focus your efforts to complete them. You can also filter them to view one or more categories at the same time.
Please note the new Achievements introduced after update 2.5 are only linked with your in-game progress and have no association with your Google Play or Game Center achievements.
