Loot box spending is consistently linked to problem gambling, research shows

Video games and gambling have been converging for years, mostly through randomized in-game purchases known as loot boxes: paid, chance-based mechanics that award a random item, character, or cosmetic. Researchers have spent the past decade asking a direct question — does spending on loot boxes behave like gambling? The accumulated evidence says, consistently, yes.

The most comprehensive answer comes from a 2021 meta-analysis published in International Gambling Studies, which pooled 15 independent studies and found a small-to-moderate positive correlation between loot box spending and problem gambling symptoms (r = 0.26, rising to r = 0.37 once the researchers corrected for likely publication bias using a trim-and-fill adjustment). A related pool of 7 studies found a similar correlation between loot box spending and excessive gaming (r = 0.25).

For context, the authors note this relationship is comparable in strength to, or stronger than, the well-established links between problem gambling and other co-occurring conditions such as depression or substance misuse — which is part of why regulators have started treating loot boxes as more than an ordinary monetization mechanic.

How common is loot box engagement among young players?

The correlation matters more because loot box exposure among young players is close to universal in some markets. According to a factsheet published by Responsible Gambling Victoria (Australia) citing research on youth gaming, 93% of adolescents and young people played at least one video game containing loot boxes in the past 12 months, and 69% went on to open one. A separate 2022 scoping review of 16 primary studies found that, among people who game generally, nearly half (45.6%) had engaged with loot boxes at some level.

Purchase rates — actually spending money, not just opening free loot boxes — vary widely by market. One U.S. study found 40.5% of adolescent gamers aged 16–18 made a loot box purchase in a given month; a Japanese study of 14-year-old gamers found a purchase rate of just 3.5%, illustrating how much regional gaming culture and monetization norms shape the numbers.

Two countries banned paid loot boxes outright

Belgium and the Netherlands have gone the furthest, treating certain paid loot boxes as a form of illegal gambling under their existing gaming laws. Belgium's Gaming Commission can pursue non-compliant publishers with fines of up to €800,000 and, in principle, criminal penalties for repeated violations. The Netherlands' gambling regulator reached a similar conclusion in 2018 — though enforcement there has been inconsistent: a Dutch court later overturned a €10 million fine the regulator had issued against EA, ruling that the loot box mechanic in question was too integrated into normal gameplay to count as a standalone gambling product.

The UK took a different path

As of 2026, loot boxes are not classified as gambling under UK law — a position held consistently by the UK government, the Gambling Commission, and the courts. Rather than a gambling-law ban, the UK has leaned on advertising standards enforcement: the Advertising Standards Authority has begun acting against app store listings that fail to disclose loot box mechanics to potential buyers before purchase.

At the EU level, members of the European Parliament's Internal Market and Consumer Protection Committee urged the European Commission in late 2025 to prohibit loot boxes and other randomized mechanics that provoke gambling-like behavior in children. As of early 2026, though, there is still no harmonized EU-wide rule — only this patchwork of national positions that studios have to navigate market by market.

Skin betting and esports wagers: where the data runs out

Loot boxes are the best-measured part of the gambling-gaming overlap; they are far from the only part. Players can also trade or wager cosmetic in-game items, or "skins," which hold real secondary-market value, often through unlicensed, offshore websites operating entirely outside the regulatory perimeter. Because that activity is unlicensed and largely unreported, no research organization currently publishes a credible estimate of how much money actually changes hands in skin betting each year. What does get measured, and is sometimes mistaken for it, is the market value of skins in circulation — a different thing entirely from betting turnover.

Esports betting, wagering real money on competitive gaming match outcomes through licensed sportsbooks, is more measurable but still far from settled. Published 2025 market-size estimates from different research firms disagree by billions of dollars, largely because each uses a different definition of what counts as "esports betting" and pulls from different regional data.

Correlation, not proof of cause

None of this proves that loot boxes cause gambling problems. The 15 studies behind the headline correlation are cross-sectional — they capture a snapshot relationship at one point in time rather than tracking the same people over years. It's possible that people already prone to gambling risk are simply more likely to spend heavily in games, rather than loot box spending creating that risk from scratch. Researchers who have examined high-spending players directly have raised exactly this question: are big spenders wealthy hobbyists, or are they players already showing signs of problem gambling? The honest answer, based on the current research base, is that the relationship is real and replicable, but the direction of causation is still an open question.

What this means for platforms and regulators

The practical upshot is a widening gap between how gambling-adjacent game mechanics are measured and how they are regulated. Loot boxes are relatively well studied and increasingly restricted in specific markets. Skin betting is barely measured at all and operates largely in the open despite being unlicensed almost everywhere. Esports betting sits in between: legal and growing, but sized so inconsistently that even industry analysts can't agree on the basic numbers. For publishers, platforms, and regulators alike, that measurement gap is itself becoming part of the story.

Methodology

Beacon Digital PR compiled correlation data from Garea et al.'s (2021) published meta-analysis in International Gambling Studies, which pooled results from 15 studies on problem gambling and 7 studies on excessive gaming. Loot box engagement and purchase-rate figures were drawn from a Responsible Gambling Victoria factsheet and a 2022 PLOS ONE scoping review by Montiel et al., and are presented separately by study and population rather than combined, since they were not collected through a single unified survey. Esports betting market-size estimates reflect each cited research firm's own 2025 published figures; Beacon Digital PR did not independently verify their underlying models. No credible, regularly published estimate of skin-betting wagering volume exists, so none is cited here.
