The video game platform Roblox has millions of users worldwide.

It primarily attracts children and young people between the ages of 11 and 19 to socialize through gaming.

- We think it's fun, you can do many different things and meet friends, says Signe.

Financial risks

Roblox is like a digital game universe with its own currency "robux".

With it, users can buy digital goods and get the opportunity to play games that you have to pay for.

The currency robux is bought with real money.

- You have to be careful as parents, the children have not learned to handle money and can be deceived, says Måns Jonasson at the Internet Foundation.
