1. Fright Dome, the glorified Halloween costume and annual highlight of the Circus Circus Adventuredome, differentiates the ticketed experience every year by partnering with a different horror film franchise for one or two of the six mazes. This year, the operation went with Texas Chainsaw Massacre, and if the terror factor wasn’t already promising thanks to the inevitability of running into the movie’s chief villain, Leatherface, and his motorized weapon of choice, it augmented the shrieking-teenager element with the unrelenting quantity of Leatherface encounters throughout the experience. You know he’ll show up at the end, but you’re not quite expecting him two minutes in. Or three minutes in. Or each subsequent time. Like your typical Grindr user, Mr. Ripcord gets around.

2. Fright Dome doubled down on flesh-eating rednecks this year by also including the Hillbilly Hell Offspring maze, which was actually scarier and more disgusting than the Texas Chainsaw Massacre attraction. When we say you’ll see some crazy sh*t in there, we mean it figuratively—and literally. That said: If there’s a maze worth the potential hour wait, it’s this one.

3. The Fright Dome crew refreshes some of the experience each year, but there’s natural deja vu, like that slovenly, Jabba-esque recreation of the surviving children’s mother in the Hillbilly haunt—a recycled prop from previous Fright Dome editions. Most of the scares still come in the form of disorientation caused by loud noises, fogs, strobe lights, claustrophobic tunnels and vile objects hanging within inches of your face. And then there was Isolation, this year’s enter-alone maze for those who ante-up for fastpasses or a VIP tour. There’s little to differentiate it from last year’s Hotel Argento, but you’ll still walk on eggshells from start to finish. There are no teenage girls in the group for the spooks to pick over the adults, meaning everyone who passes through gets jumped at.

4. The Zombie Quarantine haunt also resurfaces, but brings on more goose-pimpling this year thanks to the very real Ebola scare. There’s also another clown maze, supposedly upgraded from 3-D to 4-D. Am I the only person that doesn’t find clowns remotely horrifying?

5. Here’s something scary: Seeing the El Loco coaster car stalled mid-course and evacuated five minutes after you’ve deboarded it. Know what’s scarier? Returning to the queue and experiencing the first ride cycle after it’s been cleared to reopen in near darkness. Why not? It’s Fright Dome, where 90-degree drops and white-knuckle barrel rolls aren’t thrilling enough.

Fright Dome Days vary, 7 p.m.-midnight, $40-$90. Circus Circus, frightdome.com.
