They have been controversial in the gaming industry for their similarity to gambling, and the new rule means that every time a user buys a loot box - whether with real or in-app currency - they will know their odds of getting a prize. In May, game companies in China were required by law to disclose the odds of receiving items from loot boxes.

Singapore game developers The Sunday Times spoke with approved of Apple's move, although outside observers were less supportive. LambdaMu Games chief executive Ivan Loo said: "There are companies out there that leverage on the gambling tendency a loot box system enables, and that's bad because you don't want a person to spend beyond his means.

The unpredictability of loot boxes stimulate the production of a biochemical in the brain called dopamine, which is linked to rewards and motivation, and therefore can make loot boxes very addictive, according to Mr Michael David Thompson, a lecturer at DigiPen Institute of Technology's game software design and production department.

Psychologist Daniel Koh was critical of the move. "The rule change doesn't make much difference because addicted people will already know they are getting something. Without advertising the odds, you already have addictive behaviour.

Still, Apple has beaten Google to the punch in announcing this kind of loot-box odds rule, as Android's Google Play contains no such rules or requirements.
