Why can video game loot boxes be addictive?

Loot boxes are virtual items purchased with real money or in-game currency, containing a random selection of virtual goods. Players acquire the loot box without knowing exactly what they will receive, similar to real-life surprise bags. This system combines the direct purchase of an item with the mechanics of a slot machine and relies on probability and intermittent reinforcement to encourage repeat purchases.

Loot boxes are the subject of intense debate in both legal and ethical circles due to their similarities to gambling. Critics argue that these boxes exploit the psychological vulnerability of players, especially minors, by relying on the anticipation and uncertainty of rewards. The general consensus suggests prohibiting their use by minors and requiring transparency from adults to mitigate the associated risks of addiction.
