The in-game fees that could catch you out

Newsround has been to meet the boy who cost his mum £600 in FIFA add-ons.

Christian loves playing the football game, and he started buying FIFA points to boost his game.

What he didn't know was that he was spending his mum's money, not FIFA coins!

Giles Milton from Parent Zone told Newsround: "Players need to remember it's real money they're spending."

"This isn't Fifa coins or imaginary transfer fees."

Ayshah spoke to him about how he got caught out.
