A 15-year-old UK boy is riding the eSports wave - all the way to the bank.

Benjy Fish quit school to play games full-time, and has since managed to earn £25,000 (NZ$48,000) since turning professional in February this year.

Known professionally as Benjyfishy, he's now one of the best in the world.

"When my mum suggested I quit school earlier this year to play computer games full-time, I couldn't believe my ears. I'd always dreamed of being an eSports professional since I was about 13 years old," he told the Mirror.

"Now I can play until 4am and get up at 2pm in the afternoon. That way I can concentrate on gaming as a full-time career."

And it's turned out to be a wise career option for the young teen. He's managed to make it to the Fortnite World Cup in New York, guaranteeing himself another £50k (NZ$97k).

Benjy is in the finals for both the solo and duo version of the game, and if he wins both he would take home a sweet £4million (NZ$7.76m).

And he already has plans for if he wins - help his mum.

"I don't know what I'd buy myself but I'd love to buy a house for my mum and I," he told the Mirror.

"My dad passed away from cancer when I was only eight months old and we were made homeless and have been renting ever since. A place we could call our own would be brilliant."
