Rivalries also are prevalent in the European regional, where seven of the eight finalists are from Finland, including Tuukka Kuha, a 21-year-old from Mikkeli.
"Finnish top players know each other well, and we have faced each other many times," Kuha said. "There's some rivalry between Finns, but there are good friendships as well."
Kuha started playing competitively six years ago and plays every day to hone his skills.
Chris O'Donnell of Stoney Creek, Ontario, a finalist in the Canadian regional, has his own methods.
"I improve my skills by trying to play the toughest competition whenever possible," O'Donnell said. "I also rewatch some of my games to see where I went wrong and what I need to work on."
O'Donnell, 24, is a Toronto Maple Leafs fan who prefers to play as the Tampa Bay Lightning in NHL 18. He has been playing competitively for nine years but said he is especially proud of his success in this tournament.
"It truly means a lot to me advancing this far in the tournament," O'Donnell said. "This is the biggest tournament I've ever been a part of, and I've put a lot of work into improving my play throughout the year."
Kuha and O'Donnell each said he would save the prize money if he won. Kangas has different plans.
"It'd pay for a lot of rounds of golf this summer," he said. "I've been looking at getting a new truck, so it would for sure help with that."
