Lucky boxes, or boxes in short, are items a player can have in his/her Locker, as are keys, which are used to open the boxes. Each box is either purple, red or blue, and can only be opened on the My Locker page with a key of the same color. When a box is opened, the player receives a randomly chosen item and loses the box and the key. The probability of getting a certain item depends on the type of the box (see: Box contents). There are four different box types: Purple Box 1, Red Box 1, Red Box 2 and Blue Box 1. Keys come in only three types: Purple Key, Red Key and Blue Key.
Opening boxes is especially useful when you want to get certain items without using RT in the store. These items include many accessory items and slot changers (Red Boxes only). Moreover, by buying Blue Boxes, +1 fuses can be gotten with much less BP compared to buying the fuses directly. Instead of opening boxes, the player can also decide to sell the boxes and keys in the store for a small amount of BP. In the case of Blue Boxes and Keys, this is definitely not a good idea, since the expected sell value of the contents of a random Blue Box is over 410 BP.
You can only get keys by playing. You have a chance of getting a Purple or Red Key by finishing a game of any game mode, except Boss Battle, Zombie Infection or Singleplayer. The Blue Key is the rarest and hardest key to get. You have a chance to get it by winning a medium match of Zombie Survival, and you are guaranteed to get one by winning a hard match of Zombie Survival or beating the Crazy Cook.
