Never done a murder mystery before? Perfect.
This is not a live show where you sit, watch, and sometimes participate. Interactive means that YOU are an active and engaged part of the story.
Lost Valley Mysteries isn't about memorizing lines or being a good actor. It's about stepping into someone else's shoes, gathering clues, and figuring out whodunit alongside other guests who are just as suspicious as you are.
You'll receive your character assignment before the event — a name, a backstory, some secrets, and connections to the other guests. From the moment you arrive, you're not yourself anymore. You're someone with a motive, an alibi, and something to hide.

Lost Valley:
The Rules of Play
Character Assignments
Before the event, we'll send you a short form to help us assign characters that fit your comfort level. Here's what we'll ask:
Your name and preferred pronouns: We'll match you with a character that aligns with how you'd like to be addressed (male, female, non-binary, or no preference).
Your involvement level:
Level 1 — I want to be in the spotlight with lots of secrets and drama.
Level 2 — I'm happy to participate but don't need to be the center of attention.
Level 3 — I prefer to observe more and participate lightly.
No matter which level you choose, you'll still get a character with a backstory, secrets, and connections to the other guests. The difference is how much you're expected to drive the action.
Level 1 characters tend to have big reveals, confrontations, or pivotal clues.
Level 2 characters are solid participants with interesting secrets but less pressure.
Level 3 characters have lighter roles — you're still part of the story, but you can hang back and let others take the lead.
We'll do our best to match you with your preferred level, but character assignments also depend on which roles still need to be filled and what's available at the time you register. Some flexibility is needed to make sure the full story works. Rest assured — every character matters to the mystery.
Your character assignment will arrive via email a few days before the event. Open it, read it, and come ready to play.
How to Play
The Three-Act Structure: The game moves through three stages.
Act I: Break the ice, establish your character, and discover motives.
Act II: The investigation begins! Focus on Opportunity—who was where and what did they see?
Act III: The final reveal. Focus on Means—how was it done?
You are searching for Motive, Opportunity, and Means. You must determine: Who did it, with what, how, and why?
If your character is the victim, you stay in the game! You didn't see the killer's face, so you must still help solve your own murder.
After Act III, everyone will vote. The first person to correctly identify the killer, motive, and means wins Best Detective.
Secrets & Truths
You must be honest. Do not make up clues or lie about the information on your cards, as this could break the mystery for everyone else.
You don’t have to tell everyone everything. Use your discretion and only reveal your secrets if you are cornered or if it helps the story.
If a secret is important to the mystery, don’t worry—someone else likely has a clue card that will help them find it out!
How to Play Your Part
It is imperative for the flow of the mystery that you remain "in world" for the duration of the event.
The "Yes, And..." Rule: Use collaborative improv! If someone says something to you, accept their premise ("Yes") and build on it ("And"). Avoid saying "No" or "Yes, but."
Confrontations happen: Some confrontations between characters are scripted and will occur during Act I. If you happen to miss a confrontation, that's totally fine—the details shared are also information you'll get from others by talking.
Take the Limelight (or don't!):
If you’re bold: Be as outlandish and loud as you like!
If you’re reserved: Stand back, listen to conversations, and wait for others to approach you.
Have Fun: Above all, this is a collaborative story. Enjoy the scandal!

Frequently Asked Questions
-
Think of it as a mix between a game night and interactive theatre. Guests take on eccentric roles, follow clues, and unravel a story that blends comedy, suspense, and drama. Instead of just watching, you and your group are the ones driving the plot — creating an experience that’s as entertaining as it is unforgettable.
-
Most events run 2–3 hours, depending on the group size and how much interaction guests want.
That includes setup, gameplay, and the big reveal. For corporate retreats or fundraisers, we can expand the timeline to include networking, catering breaks, or auctions.
-
Our mysteries scale from 8 guests in a living room to 100+ in a banquet hall.
We’ll guide you to the right package based on your group size so everyone has a role and stays engaged.
-
Costumes are optional but highly encouraged! We provide style suggestions for each mystery (e.g., 90s mall vibes, glamorous gala, modern influencer looks). Guests who want to keep it simple can play just fine without dressing up.
We also offer the potential for prizes at the end, with a voting prize (voted by party-goers) for Best Dressed, if you’re feeling extra competitive.
-
Absolutely. We can weave in inside jokes, company values, sponsor shoutouts, or nods to the guest of honor.
For sororities and bachelorettes, we often add personalized roles or clues for the bride-to-be.
For fundraisers, we’ll highlight the cause so it’s part of the story.
-
Most mystery parties are one-off games. Lost Valley Mysteries is built as a shared-universe: all our stories happen in the same fictional town with recurring characters, scandals, and history. That continuity makes the experience richer — your group isn’t just solving a case, you’re stepping into a living world that evolves with every event.
-
Not at all. Each mystery stands alone, so you can jump in fresh and have a great time.
But for returning players, there are hidden connections and Easter eggs that tie events together — making repeat bookings extra fun.
-
Anywhere you choose: private homes, sorority houses, offices, restaurants, breweries, banquet halls — even outdoor spaces. We bring the props and facilitation; you provide the location.
-
We can scale the content. Some stories are lighthearted and playful, others lean more dramatic. We’ll discuss your group and adjust accordingly (family-friendly, adult-themed, or professional).
-
As long as you have enough room for guests to mingle, sit, and move around, we can adapt. For larger events, venues with tables or breakout spaces work best.
-
Yes — role cards, props, story materials, and a facilitator to run the show. You only need to provide the space and whatever food/drinks you’d like for your guests.
-
Because every story adds a new layer to Lost Valley. Guests love seeing how characters, scandals, and clues connect across different events. It’s not just one game — it’s an evolving world they can revisit again and again.
