Magic Box Rewards
When you use the "Magic Box" power-up and daub the correct number with the box icon, you collect a Magic Box. These are opened after the round is over, giving you random extra rewards, given you have enough keys to do so!
Among other rewards, it is possible to get Collection Pieces out of Magic Boxes. Collection Pieces are stickers that go into your Collections. If you collect all 8 pieces in one room, you will get an increase to the daily "Collect" bonus tickets!
