Both of these cases are available in the Shop.
This case contains only a few ball cards, but it has a 100% chance to unlock a new ball.
If you've collected all balls, you can continue upgrading them by purchasing Upgrade Cases.
These cases contain numerous ball cards, and they will help you upgrade your balls. The number of cards in each case depends on your highest available Alley. You can't get new Balls from these cases.
Exception: if you have no Rare or Epic Balls in your collection, opening an Upgrade case might give you new Balls of these rarities.
There are 3 tiers of Upgrade Cases:
|Tier 1: Bowler Case||Tier 2: Master Case||Tier 3: King Case|
The higher the tier of an Upgrade Case, the more cards will be in it!
You can also get a bundle at a lower price.
