Loot box
In video games, a loot box (also called a loot crate or prize crate) is a consumable virtual item which can be redeemed to receive a randomised selection of further virtual items, or loot, ranging from simple customisation options for a player's avatar or character to game-changing equipment such as weapons and armour. A loot box is typically a form of monetization, with players either buying the boxes directly or receiving the boxes during play and later buying "keys" with which to redeem them.
