TMZ Games

John Mayer's taking his show on the road ... to make a special guest appearance on the popular live trivia game, HQ Trivia.

Sources close to the singer-songwriter tell TMZ ... he'll join host Scott Rogowsky -- aka Host Malone, aka Quiz Khalifa, aka Trap Trebek -- Sunday night to turn the daily game show into a wonderland ... with a prize of $25,000.

We're told John's set to queue up a question or 2 for all the HQties out there ... much like Robert De Niro did recently. Other celebs like The Rock and Jimmy Kimmel have guest hosted as well. We've learned John will also belt out a tune during the show's broadcast.

Chad Ochocinco is more FIFA Prince than FIFA King ... 'cause Paul George OWNS the ex-NFL superstar in the video game -- so says the Thunder stud himself.

Chad -- who's dubbed himself the "FIFA King" many times over the years -- has been obsessed with the soccer game ... and is a legend in the gaming community for showing up to random people's houses to pick up the sticks.

But PG-13 says the ex-NFL star is all talk ... and he NEVER wins when the two play.

"There's one person that can't beat me ... Ochocinco," Paul told TMZ Sports at the Fortnite Pro-Am on Wednesday.

It's huge if true ... 'cause just the other day Chad said he was in the FIFA lab for EIGHT STRAIGHT HOURS.

You don't gotta be an NBA star to pull world-class chicks -- because pro gamers are doing pretty damn well these days ... this according to Fortnite god Ninja.

With gaming events like Fortnite and League of Legends selling out stadiums -- yes, STADIUMS -- pro gamers are making more cash and are becoming more famous than ever.

So, when we saw Ninja at the Fortnite Pro-Am at the E3 convention in L.A., we asked how he felt about that old stereotype that gamers are just nerds who live in their parents' basement.

Bottom line ... if you're still thinking that way, you're living in the stone age.

"I think that if they want to, [pro gamers] can have relationships, find relationships from their popularity just like professional basketball players can go out and if he's not married ... probably find someone."

He's right. Case in point -- FaZe Censor ... a pro gamer who's dating SMOKING HOT WEATHER GIRL YANET GARCIA!!!

There's more ... Ninja also says there was a celebrity at the Pro-Am who's got real skills on the sticks. And after some sleuthing, we found out the guy he's talking about is Chicago Bears running back Tarik Cohen!

So, if the whole NFL thing doesn't work out, sounds like the pro-gamer life is a pretty sweet gig!!!
