There are several ways you can get union points.
Most points are awarded for completing union quests, both common and individual.
You can also earn points by doing the following:
- Visiting the game daily.
- Helping your fellow unioners on their islands.
- Making certain in-game purchases.
- Taking certain prize places in competition, mini-game, rankings, Beach Battle, Snowball Fight, and Rhee the Monkey rankings.
- Completing certain holiday quests and massive projects.

You can always find out how many union points you will receive for completing a quest by checking any of the active tasks in the window of your union.
