"Children are being lured into online gambling - not done with real money, but with the accessories that go with certain online games. Sometimes these are "skins" (cosmetic enhancements for in-game weapons), sometimes "coins". In some cases, the skins are worth tens of thousands of pounds, and can be bought and sold on third party websites. As a result they've become an alternative currency, easily accessible to children - although their parents probably know nothing about it. Some children have run up serious debts. It's a business worth billions of pounds a year."
