Vaults drop a Resource Box 1/3 of the time, drop a Prize Box 1/3 of the time, and offer the choice of a Crypto Prize Box or a Resource Box 1/3 of the time. These Boxes contain various game items according to the vault color.
Every day a random hour is selected to be Happy Hour. During Happy Hour a random category is boosted! Solving questions from a boosted category yields 500 paint in White Vaults and Blue Vaults.
Event Resource Boxes
During events, an alternative resource box will drop, containing event related resources rather than paint.
