Samsung recruited the world's top 'Fortnite' player for a tournament showing off their new smartphones

Samsung 837's three-story video wall showed off the action from the Level Up "Fortnite" tournament.

Tyler "Ninja" Blevins, the world's most popular "Fortnite" player, was in attendance; he helped launch the Galaxy S9 last year too.

The winners of Level Up's "Fortnite" tournament got to meet Ninja and earned Galaxy S10 phones for their efforts.

Korean pop group iKon was also on hand for an exclusive performance.

"Fortnite" has a special skin based on iKon member Jung Chanwoo; only people who buy the Galaxy S10 will be able to unlock it.

Fans packed the house for iKon's performance and a special panel discussion with Ninja and the group.

In case you're wondering what iKon's music sounds like, you can listen to one of their top tracks here.

Later in the day, Ninja and the members of iKon played with fans on a new Creative Island in "Fortnite" made exclusively for Level Up.

Everyone at Level Up was playing the mobile version of "Fortnite" on the Samsung Galaxy S10.
