More regulation is needed to limit gambling-like practices in video games, researchers have warned.

A new study into the harmful risks of gambling on young people found loot boxes blurred the line between gaming and gambling.

Loot boxes are a feature where gamers use real money, or in-game currency, to buy mystery virtual items for use within the game.

Bournemouth University researchers, led by Dr Ruijie Wang, discovered half of loot box users displayed some level of gambling risk.

Dr Wang, senior lecturer in psychology, said loot boxes were not officially classified as gambling in the UK.

She said: “They are often used in video games aimed at young people, allowing players to pay for random prizes like in-game items and progress in the game.

“But they can blur the line between playing and gambling because players spend money without knowing what they will receive, which can lead to impulsive spending and addiction.”

The study, funded by GambleAware, involved 40,000 participants over the course of three years.

It found that 76% of people using physical gambling machines and online casino games experienced “problem gambling”.

Zoe Osmond, CEO of GambleAware, said: “This new research shows that there are some particular types of gambling which can lead to an increased chance of experiencing gambling harm, which can have a corrosive effect on people’s lives, finances, careers and relationships.”

Dr Wang said the study’s recommendations included stricter regulations for electronic gaming machines and for online casino games, with additional protective measures needed for young people, such as setting minimum age limits of 18 for features such as loot boxes.

“We also suggest operators to collaborate to create shared customer databases to support individuals engaging in multiple gambling activities,” she added.
