How do I open my prize boxes?

Your 4 most recently won prize boxes are stored in the 'prize box drawer', which can be opened by tapping on the 'prize box icon' at the bottom of the game window. To open a prize box, the required time must elapse to unlock that box. You can only have one prize box unlocking at one time. You can also instantly open a prize box by using chips. Each 10 minute time period costs 1 chip.

Purchased prize boxes can also be opened instantly.
