possibly Mazes and Monsters by Rona Matter?

"Part thriller, part love story, Mazes and Monsters is a spellbinding novel about a group of college students in the 1980s who use a fantasy game as refuge from their personal, emotional, and social problems. Based loosely on the “steam tunnel incidents” of the 1970s, the four friends—Kate, Jay Jay, Daniel, and Robbie—eventually take their game too far when they decide to live-action role-play in the caverns near their college campus. What follows is terrifying and unexpected, as each character dives deep into the darkest part of their mind, those forbidden places where our most menacing truths lie."

Tyler, what's the genre (which we need to add to the header/ topic title) - e.g., YA horror, thriller, fantasy, mystery? Something from a series by R.L. Stine?

How old are the kids? Boys and girls?

Can you describe some of creatures or other things that come to life? Where did they find/ get the game?

I added a few details and a spoiler alert to the header. Feel free to edit it.
