Vegas casino murder mystery
Seventies Las Vegas is pure party fuel: wide lapels, sequined jumpsuits, lounge singers, high rollers and a casino floor where everyone is watching everyone else. This theme is set at the Gilded Cactus Casino & Lounge on the night of its grand reopening, and it pairs a murder mystery with a casino night, so guests can play blackjack for chocolate coins between rounds while they trade accusations.
The era is a gift to hosts because it's so easy to dress for. Thrift stores are full of polyester shirts with pointed collars, bell-bottoms and gaudy jewelry, and a green card-stock dealer's visor costs pennies. Nobody needs to know how to gamble, either. The tables are a fun backdrop played with toy chips or candy, never real money.
Killer Cast writes the case for your actual guest list, so each friend becomes a suspect: the pit boss who watched every table but one, the headliner with a contract dispute, the high roller who hasn't cashed a single chip. Every guest gets a private invite page with their character, costume ideas and an optional illustrated portrait made from their selfie in a 1970s airbrushed-poster style. Narrator audio with captions runs the night from your TV, and the interactive Evidence Locker deals out items like matchbooks, keno slips and casino-cage receipts as each round unlocks. It's built for 6 to 20 adults, and the host can play a suspect or run the floor.
The Gilded Cactus Casino & Lounge on the Las Vegas Strip, on the night of its grand reopening. The headliner is warming up in the showroom, the high rollers are at the tables, the count room is stacked with cash, and before the last hand is dealt the house loses more than money.

Meet the
suspects
Charlie Lucero
The pit boss
Runs the blackjack pit with a sharp eye, a clipboard nobody else may read and a handshake that seals more deals than any contract.
“Watched every table on the floor tonight except the one that mattered.”
Costume ideas: A dark suit or pantsuit with a wide-collared shirt, a clipboard and a pencil behind the ear, Tinted aviator sunglasses.
Skyler Sterling
The showroom headliner
Sings two sold-out shows a night and has a dressing room bigger than most apartments on the Strip. Skyler's contract is up for renewal, and the negotiations have been loud.
“Has a new contract in the dressing room with somebody else's signature on it.”
Costume ideas: A sequined jumpsuit, gown or rhinestone jacket, a feather boa or silk scarf, a microphone (a hairbrush counts).
Dallas Calhoun
The high roller
Flew in from Texas with a suitcase of cash and a lucky silver dollar. Dallas bets big, tips bigger and never seems to lose.
“Won big at 11:15 and hasn't cashed in a single chip.”
Costume ideas: A Western-cut leisure suit or a wide-collared shirt with a bolo tie, a big silver belt buckle, a stack of toy chips in a shirt pocket.
Sam Navarro
The blackjack dealer
Deals the fastest game on the floor and can track a six-deck shoe without blinking. Sam sees every hand and forgets none of them.
“Dealt a perfect hand at table six, then quietly asked to go on break.”
Costume ideas: A white shirt, black vest and bow tie, a green dealer's visor, Sleeve garters made from two elastic hair ties or ribbons.
Leslie Lattimore
The casino bookkeeper
Keeps the Gilded Cactus accounts balanced to the penny, at least on paper, and knows exactly how much cash moves through the count room each night.
“Knows the count room came up $40,000 short at midnight, and hasn't told a soul.”
Costume ideas: A brown or plaid suit with a wide tie, or a printed wrap dress, Thick-rimmed glasses frames, a ledger and a roll of adding-machine tape.
Lou Garrity
The cocktail server
Has worked every corner of the casino floor for fifteen years and knows every regular's drink, tab and tell.
“Carried a full tray into the count room at 11:40 and came out empty-handed.”
Costume ideas: A sequined vest or satin shirt in a loud color, a cocktail tray (a round pizza pan works), a notepad and pencil.
Tracy Sparks
The lounge magician
Pulls doves from top hats and aces from thin air between sets in the Starlight Lounge. Tracy insists it's all misdirection.
“Made a stack of rare $5,000 chips vanish on stage tonight. They haven't reappeared.”
Costume ideas: A velvet jacket or a cape with a satin lining, a deck of cards that never leaves your hands, a wand made from a dowel painted black with white tips.
Blake Mercer
The house detective
Hired to keep an eye on the high rollers and the help, Blake spends long hours up in the eye in the sky and very little time explaining what goes on up there.
“Was paid to watch the owner tonight and ended up watching someone else.”
Costume ideas: A trench coat or plaid sport coat, a notepad and a pencil stub, a cheap pair of binoculars.

Questions
Do guests need to know how to gamble?
No. The mystery is the main game, and the casino tables are just a fun backdrop between rounds. A one-card blackjack cheat sheet is all anyone needs, and the dealers can teach as they go.
Is there real money involved?
No, and we recommend keeping it that way. Use toy chips, candy or chocolate coins, give everyone the same starting stack at the door and trade chips for silly prizes at the end. The stakes are bragging rights, not wallets.
What did people wear in 1970s Las Vegas?
Glamour turned all the way up: sequined gowns and jumpsuits, wide-lapel suits, leisure suits, kaftans, tinted aviator sunglasses and plenty of gold. Casino-staff looks (white shirt, black vest, bow tie, green visor) are an easy option too.
How do we run a casino night and a murder mystery at the same time?
Open the tables during arrivals and between rounds, then pause play whenever the narrator audio starts a new scene. The cards give guests something to do with their hands while they eavesdrop and trade secrets.
Can the host play a suspect?
Yes. Play a suspect alongside everyone else, or run the night as the pit boss: start the narrator, keep the rounds moving and hand out the chips.
How much prep does it take?
Your custom case is ready in minutes and everything is digital, so there's nothing to ship. Most of your prep goes into the fun part: a green tablecloth, a couple of decks of cards and a mirror ball.
