Apple has changed the rules around how games on its app store use loot boxes.
These boxes are random rewards for gameplay and often give players benefits and power-ups that can be used in games.
In a change to its developer guidelines, Apple said games must now let players know the odds of getting particular items in the boxes. In the updated guidelines, Apple said any in-game mechanism that rewards players with randomised virtual items
must list the odds of receiving each type of item. In addition, it said, customers must be informed of these odds before they buy the boxes or rewards.
Many games offer extras to players that can change the appearance of the game, introduce new characters or bestow power-ups that help people as they play. Some titles let people buy loot boxes with in-game funds they generate by playing or by
spending real money to purchase the game's virtual cash.
