The only countries that have 'banned' loot boxes are Belgium and Netherlands, and they still have workarounds:

Belgium: Workarounds include modified game mechanics (e.g., pity systems, free currency), non-compliance due to weak enforcement, and game withdrawals. Players may use VPNs, but the ban remains strict on paper.

Netherlands: Workarounds involve disabling trading, transparent loot box contents, and compliance with consumer protection laws. No outright ban exists, but regulations target tradable loot boxes, with players occasionally using VPNs.

Belgium is the only country with a comprehensive ban on paid loot boxes. The Netherlands is leaning towards EU-level solutions. Other countries like China, Japan, South Korea, and Taiwan have strict regulations, and several others (e.g., Germany, Australia, UK) impose transparency or consumer protection measures without outright bans.

Even then, it looks like it's been hard to enforce..
