The suspect, who police believe to be 24-year-old David Katz from Baltimore, Maryland, shot himself dead before police arrived.
The shooting occurred at GLHF Game Bar in downtown Jacksonville, which was hosting Sunday’s event that police say the suspect was attending.
Gunshots were heard as gamers live-streamed a regional qualifier for a new football video game, Madden NFL 19.
Police are investigating an online video which appears to show the scene right before the shooting.
A red dot that appears to be a laser pointer can be seen on the chest of one of the players before the first of around a dozen gunshots were fired.
Jacksonville Sheriff’s Office said they believed the suspect travelled from Maryland and had stayed in a hotel the night before.
A total of nine people were shot, and two were injured fleeing.
Their conditions are not life-threatening.

No one deserves to die over playing a video game, you know? said Derek Jones, who was taking part in the tournament.
The 30-year-old, from New Mexico, said he was sitting in a back patio outside the venue when he heard the gunshots.
He jumped over a fence and fled, leaving behind his backpack and phone.
You know, I’m glad I lost today, Mr Jones said.
Because if I’d won, I would have been in that game bar right then playing a game and not paying attention.
And he could have come and I’d probably be dead right now.
Jason Lake, the founder and CEO of compLexity, a company that owns professional esports teams, wrote on Twitter that one of his players, Drini Gjoka, was shot in the thumb.

He added in another message I am literally so lucky. The bullet hit my thumb. Worst day of my life.
Police say the motive is still unclear, and it is unknown if the victims were known to the suspect.
