Due to the large number of ghosts they can hold, haunted houses are consistently scarier than cursed sleeping bags, possessed lean-tos, and ectoplasmic studio apartments. Give your goose bumps a worthwhile workout with today's Groupon: for $5, you get one ticket to the Freakling Brothers Trilogy of Terror, which allows access to one of three horror attractions. Get your shriek on October 1–3, 8–10, and 15–31 from 6:30 p.m. to either 10:30 p.m. or midnight.

Fear is the secret to happy marriages, lasting friendships, and the final ingredient in numerous madman-created serums. Lead your scared sweetie and ghoulish gang through one of the three distinct scare lairs at the Freakling Brothers Trilogy of Terror. Dark rooms and mysterious corridors wind throughout Castle Vampyre, where a force of unadulterated evil always lurks a few steps behind in an interactive and startling experience that stokes primal fears, such as that of missing a student loan payment. Alternately, a terrifying troupe of circus freaks and clown college dropouts prowl the Circus of Horrors campus quad, featuring a labyrinthine den of monstrous inflatable balls and dead ends. Macabre screams of anguish ring through the air at the third house of horror, the Mortuary, which is in its final year at the Trilogy before its proper burial.

The Freakling Brothers' rotating fleet of experienced phantoms and fiends have honed their moans in a freestanding horror attraction since 1992, the first year spirit gum was Ghostbusted by the FDA. The team's minimal use of props and fake blood leaves the focus on digging deep into the scare psyche.

No children under age 5 are allowed; all children under age 12 must enter with a companion.

EDGE: Las Vegas has profiled Freakling Brothers Trilogy of Terror haunted houses. Freakling Brothers appear in this Halloween weather forecast, and they have more than 600 Facebook fans.

• The Freakling Brothers don’t use a lot of fake blood or gore effects, either. And they don’t employ dozens of costumed actors. Just 15 in each location. Yet, their haunted houses are some of the scariest, most creative that I have ever seen. – Blake French, EDGE: Las Vegas
