Sixteen-year-old Kyle Giersdorf — screen name “Bugha” — took home $3 million Sunday after winning the inaugural Fortnite World Cup in New York, the largest-ever prize for a singe player in a videogame tournament.

The Pennsylvania teen crushed his competition at a sold-out Arthur Ashe Stadium — home of next month’s U.S. Open tennis tournament — to capture the solo division with 59 points, 26 more than his runner-up. About $30 million in prize money was up for grabs at this weekend’s tournament.

Giersdorf’s mother, Darcy Giersdorf, told ESPN that he typically plays “Fortnite” eight to 10 hours a day. “This is life-changing for him,” she told ESPN. “He’s been playing videogames since he was 3, so this is his passion. He told us he could do this, he put his mind to it and he did it.”

“Fortnite” is the most financially successful free videogame of all time, earning $2.4 billion in revenue in 2018, according to Nielsen’s SuperData Research.
