Two large studies have found a link between loot box spending and problem gambling

Many popular games allow people to pay a small fee to obtain a “loot box” containing random selections of virtual in-game items. New research has found that there is a significant relationship between problematic gambling behaviors and spending money on loot boxes.

The findings, which appear in the journal PLOS One, indicate that people who spend more money on loot boxes are also more likely to be unable to keep their gambling habits in check.

“Loot boxes are extremely widespread. A recent analysis we did showed that they may feature in as many as 63% of mobile games. They’re extremely profitable, too: They’re estimated to have perhaps generated as much as $30 billion in revenue in 2018,” said study author David Zendle of York St. John University.
