Introduced in Update 4.8, Piggy Bank Events are limited-time events in which Trainers reach individual milestones and collect rewards through spending Gems on any feature in the game. Each one Gem spent is equal to one Gem added to the bank, regardless of what it was spent on. Leveling up earns 20 Gems and completing a collection earns 50 Gems. Gems are not automatically added to the Trainers Gems bar, they must be manually collected from the bank. A minimum number of Gems must be earned before the bank can be broken to retrieve any Gems. There is a maximum limit on the number of Gems that can be earned throughout the event, which varies for each event. The event banner will display 'FULL!' upon reaching the maximum capacity. Trainers must pay real currency to break the bank. Upon breaking the bank, VIP points equal to the number of Gems collected will be awarded. Once the bank has been broken and the Gems collected, the event will disappear, regardless of whether the time limit has expired. Any Gems not collected before the end of the event will be lost. These events start and end at 12:00 UTC.
