The fraud reporting centre, which is run by the City of London Police, said it had seen a more than 40 percent rise in crimes involving the hit video game, with victims losing on average £110 each time.
Fortnite, which is certified as being suitable for children aged 12 and over, is set in a dystopian world where most of the Earth’s population has suddenly disappeared, living tough conditions and zombie-like creatures to roam the Earth. Players are among the remaining 2 per cent whose job it is to survive and return the earth to normal.
The scam works by convincing players to leave the game and enter a third party website, where they can buy “free” online currency which they can use in the game to buy items like weapons and clothes. To “verify their account is real” players are asked to hand over bank details.
Parents are now being urged to be vigilant in the run-up to Christmas and keep an eye on what their children are doing online.
Chief Inspector Paul Carroll, of the National Fraud Intelligence Bureau, said: “Clearly you expect there to be more purchases of Fortnite over the Christmas period, it’s the in thing for gamers. So it is certainly a time for parents to be vigilant and get their knowledge up to speed of what it entails.
“You have always got to question requests for personal financial information.”
Figures seen by the Sunday Telegraph showed that between May and November this year there had been 50 reports of fraud to the hotline involving Fortnite.
This was a rise on previous figures released by the centre that showed there were 35 crimes reported between September last year, when the game was released, and April.
The centre warned that many of the frauds came from children being tricked by scams on social media promisings free ways to get Fortnite’s in-game currency, called V-Bucks.
V-Bucks can be bought with real money or earned playing the game and allow players to buy new items for their online fortnite v bucks generator characters such as costumes, weapons or dance moves.
The Sunday Telegraph found a number of Fortnite scam sites on Facebook and YouTube, which typically took people to a third-party website where they were told they could get free V-Bucks by simply entering their Fortnite account username.
