Stadium Bingo is an ongoing mission Event. When you reach player level 3, you unlock the ability to play Bingo mission cards.
The objective is to complete the entire bingo card for a major reward. While you complete a single line bingo, you will be rewarded with smaller rewards, such as Item Tickets, coins, hearts, or rubies.
Bingo Cards[]
There are multiple bingo cards each with their own rewards. You can swap between any of the other cards at any time. But you will only be able to play one card at a time. However switching from League Battle to Mission Bingo will pause any accumulation of League Points until you switch back to League Battle play.
