Throw the Best Adult Halloween Party: 10 Spooky Activity Ideas!

So, you want to throw an adult Halloween party that people actually remember and don’t just show up to for the free booze? Good call. Because let’s be real—Halloween isn’t just for kids anymore. We’ve traded pillowcases full of candy for cocktails, costumes, and a few spooky shenanigans that make the night unforgettable.

And if you’re worried that your party might end up being just a bunch of adults sitting around awkwardly in masks, don’t sweat it. I’ve pulled together 10 spooky activity ideas that’ll turn your bash into the kind of Halloween party your friends will talk about until at least New Year’s (and maybe regret in the group chat the next morning). Ready? Let’s do this.

1. Host a Killer Costume Contest 🎭

No adult Halloween party is complete without a costume contest. But please, don’t make it boring. “Best Costume” is fine, but spice it up with categories like:

• Most Extra Costume (for the person who clearly spent three paychecks and lost sleep over hot-gluing sequins until 3 AM).
• Funniest Costume (the person who shows up as a sexy traffic cone deserves recognition).
• Creepiest Costume (basically, whoever makes you question whether they’re secretly auditioning for a horror movie).
• Have a simple outfit; you can kill the entire look by simply wearing a Halloween-themed t-shirt. You can have it easily from here!

Pro tip: Don’t just hand out lame plastic trophies. Give out prizes like a bottle of wine, a spooky cocktail kit, or even a tacky Halloween decoration they have to display at home. Ever seen a grown man forced to keep a six-foot inflatable skeleton in his living room? Pure comedy gold.

2. Spooky Cocktail Tasting 🍹

Forget jungle juice. This is an adult Halloween party, and your drinks deserve better. Set up a spooky cocktail bar with themed drinks like:

• Bloody Mary Syringes (literally serve shots in plastic syringes—it’s equal parts creepy and fun).
• Witches’ Brew Punch (bonus points if you use dry ice for that “is this safe to drink?” foggy effect).
• Vampire’s Kiss Martini (cranberry juice + vodka + black sugar rim = classy yet sinister).

If you’re feeling fancy, make it a tasting challenge. Line up a few creepy concoctions, blindfold your friends, and see who can guess the ingredients. Warning: someone will gag, and everyone else will laugh.

If you want something extra, you can have cup stickers too, check it out here!

3. Creepy Murder Mystery Game 🕵️

Want your guests glued to the fun instead of their phones? Murder mystery games are perfect for Halloween. Hand out character cards, dim the lights, and let everyone act out their roles. It’s basically Clue, but with more cocktails and bad acting.

IMO, this is a great way to get people out of their shells (and into some ridiculous accents). Ever seen your quiet coworker commit to being Count Dracula all night? Priceless.

4. Pumpkin Carving… with a Twist 🎃

Yes, carving pumpkins sounds wholesome, but adults know how to make anything competitive. Split into teams and host a Pumpkin Carve-Off. Add twists like:

• Speed Round (who can carve the fastest without losing a finger).
• Most Inappropriate Pumpkin (NSFW carvings always happen—just prepare yourself).
• Glow in the Dark Challenge (give them glow sticks or LED candles to light up their creations).

Messy? Yes. Worth it? Absolutely.

5. Creepy Photo Booth 📸

Let’s be honest—half the point of Halloween parties is the Instagram content. Set up a DIY spooky photo booth with:

• A creepy backdrop (think spider webs, black sheets, or a fake graveyard wall).
• Props like skull masks, witch hats, and bloody plastic chainsaws.
• A cheap ring light for that perfect “creepy yet fabulous” glow.
  
  

Trust me, once the cocktails kick in, people will spend more time here than on the dance floor.

6. Scary Movie Drinking Game 🎬🍺

Not everyone wants to dance all night, so why not set up a cozy corner for a horror movie drinking game? Pick classics like Halloween, Scream, or even Hocus Pocus if you want less gore.

Make a rule sheet like:

• Take a sip when someone screams.
• Chug when someone runs upstairs instead of outside.
• Take a shot when the creepy kid sings a nursery rhyme.

Just be prepared—nobody makes it to the end of The Exorcist without regretting it the next morning.

7. Haunted House Walkthrough 👻

Okay, this one’s extra, but if you want to go all out, turn part of your house (or backyard) into a mini haunted house.

• Use black sheets to create “walls.”
• Hide friends inside with masks to jump out at people.
• Add creepy sound effects like whispers or chains rattling.

It doesn’t have to be pro-level like Universal Studios. Even a half-baked haunted hallway gets people screaming (and let’s be real, screams = entertainment).

8. Adult Trick-or-Treat 🍬🍸

Who said trick-or-treating is just for kids? Put an adult spin on it:

• Instead of candy, fill bowls with mini liquor bottles, scratch-off lottery tickets, or cheeky adult goodies.
• Have guests “trick-or-treat” at different rooms in your house.
• For the trick option, dare them to do something embarrassing—like dance to “Thriller” in front of everyone.

Honestly, this one’s my personal fave. Because who doesn’t want to leave a party with candy and tequila?

9. Spooky Karaoke Night 🎤

Few things scream “Halloween party” like your friends belting out Monster Mash at 2 AM.

Queue up a playlist with songs like:

• “Thriller” – Michael Jackson
• “Disturbia” – Rihanna
• “Highway to Hell” – AC/DC
• “Somebody’s Watching Me” – Rockwell

Add a rule: if someone refuses to sing, they have to take a shot. Suddenly, everyone’s Mariah Carey.

10. Midnight Scavenger Hunt 🔦

End the night with a spooky scavenger hunt. Hide creepy objects around your house or yard—fake spiders, skulls, or envelopes with dares inside.

Make the rules simple:

• First person/team to find everything wins.
• Loser has to wear a ridiculous costume piece for the rest of the night (giant pumpkin hat, anyone?).

It’s chaotic, hilarious, and the perfect way to keep the energy going when people start to crash.

Quick Pro Tips for Hosting the Best Halloween Party

Alright, before I wrap this up, here are a few extra things to make your adult Halloween party smoother than a witch’s brew martini:

• Set the vibe with lighting. Candles, string lights, and a fog machine do wonders.
• Make a playlist ahead of time. Don’t rely on YouTube ads to kill your spooky mood.
• Have a backup plan. If an activity flops, move on quickly—no one remembers what you skipped, only what you nailed.
• Don’t forget the snacks. Yes, people want cocktails, but trust me, drunk guests need nachos at some point.
