If you aren’t familiar with Roblox, then you probably don’t have any children in your life. The online gaming platform has over 85 million daily active users, and most of them are children. If you’re a parent or guardian, your child has probably asked you for Robux (the gaming platform’s currency) on more than one occasion.

The craze is so big that it has even hit the children of Westeros. Dexter Sol Ansell will be playing Egg in HBO’s upcoming Game of Thrones prequel A Knight of the Seven Kingdoms, but when he’s not filming the series, he’s playing Roblox.

“I’m like Robloxy. I’m a Roblox kid,” Dexter Sol Ansell tells Popverse’s Ashley Victoria Robinson during a New York Comic Con interview.

This means that if your child has ever been on a Roblox server, they might have been playing alongside Egg.

Ansell’s costar Peter Claffey (who plays Dunk) hasn’t been bitten by the Roblox bug, but he enjoys story-based console games. “I’m not an online gamer,” Claffey says. “I want to sit down and just be engulfed in the story. I just finished playing Spider-Man 2. And I don’t feel like it was the first Spider-Man, but it was still awesome. And Venom being back and all those things.”
