Boxes

Boxes are a feature in Fruit Ninja and Fruit Ninja 2. They can be opened to obtain new blades, or duplicates used to upgrade them. Only the boxes in Fruit Ninja reward dojos. Red and Purple boxes are exclusive to Fruit Ninja, meanwhile watermelon, pineapple, dragon fruit, and cosmic berry boxes are exclusive to Fruit Ninja 2. They can be earned through events or purchased from the store for gems.

Obtaining
Fruit Ninja:

Red and purple boxes can be purchased from the store for 60 and 120 gems respectively. They can also be earned in event mode. Red boxes were available as rewards from the 12 days of gifts from the store.

Fruit Ninja 2:

Boxes can most commonly be obtained as rewards from events. The best boxes will often come from the highest rewards. Like the above mentioned red and purple boxes, these boxes can be purchased from the store as well.

They can also be grown in the garden, though higher level boxes will be much rarer.
