Scott Rogowsky, host of the popular mobile quiz game HQ Trivia, had a sad message for its fans and players this weekend. In a Twitter video post, Rogowsky announced, "It is with a heavy heart I must share some tragic news that has befallen the HQ family. Our friend and founder Colin Kroll passed away unexpectedly early this morning at the age of 34." Kroll was found unresponsive in his Manhattan apartment on Sunday. He was pronounced dead at the scene.
