The Mystery League

What The Mystery League does

The Mystery League is a Chicago-based puzzle design company founded in 2015 and operated by Sandy Weisz. It designs and delivers immersive puzzle experiences — tabletop games, custom adventures, remote team-building events, destination games, and large-scale alternate reality games (ARGs) — for corporate clients, brands, museums, and private celebrations. Its flagship titles include Search for a Superhero, Mystery in the Galleries, The Unknown Islands, Creatures on the Loose, and the award-winning immersive escape room The Last Defender. Notable engagements span Salesforce, Accenture, Google, Meta, McKinsey, BCG, Uber, Citadel, F5, the Museum of Science and Industry, Field Museum, Alinea (Pilcrow Bar, 10,000+ participants in 2020), and Cards Against Humanity (Hanukkah LOL, 6,000+ solvers). The company supplements services with two wholly-owned digital sub-brands: Signals, a monthly puzzle newsletter with a paid Boosters tier, and Raddle, a standalone daily word-ladder puzzle game launched in 2024.

Revenue mechanics are diversified across five streams: project-based custom event design and production (one-time license), ticketed public events (e.g., $62 per team-of-four for Mystery Trivia Night), Signals newsletter subscriptions (recurring), Raddle (freemium), and large-scale ARG design for brands (professional services). Pricing is quote-based for custom work and varies by complexity, duration, player count, and venue. Go-to-market combines direct enterprise outreach ([email protected]), community-led growth via the Signals newsletter, social media (Instagram, X, Bluesky, Threads, Mastodon, Discord), earned media through NPR Sunday Puzzler and Hey Riddle Riddle podcast appearances, and recurring ticketed events at Chicago venues. Geographic reach is primarily Midwest/National for live services, with global reach for digital products (Raddle, Pilcrow Bar) and select remote builds. The business is founder-owned, bootstrapped, and operates with 1-10 employees.

Direct peers

• Watson Adventures: NYC-based company offering corporate team-building scavenger hunts and puzzle adventures in museums, neighborhoods, and landmarks. Directly comparable to The Mystery League's destination games and corporate team-building business model, with a similar mix of in-person, story-driven puzzle experiences for enterprise clients.
• Strayboots: Corporate team-building scavenger hunt company with a mobile app platform for self-guided and hosted experiences. Competes in the same corporate team-building market as The Mystery League with a more technology-platform-centric delivery model.
• Teambuilding.com: Corporate team-building services company offering a wide catalog of virtual, in-person, and hybrid team activities. Competes with The Mystery League in the broader corporate team-building market, though with a more commoditized, catalog-based delivery model.
• The Escape Game: US-based escape room chain with multiple locations and strong corporate team-building offering. Competes with The Mystery League in the immersive puzzle experience category, though anchored to fixed retail venues rather than custom on-site designs.
• Puzzle Break: US escape room company with multiple locations and corporate team-building programs. Directly comparable in the escape room category with a similar mix of physical and remote team-building offerings.
• 60out Escape Rooms: Escape room chain with multiple US locations and a corporate events program. Competes directly in the escape room and corporate team-building market, with similar in-person, story-driven puzzle experiences.
• CityHunt: Corporate team-building company specializing in scavenger hunts and team adventure events in cities. Directly comparable to The Mystery League's destination games and corporate event business with similar target buyers (corporate team-building coordinators) and use cases.

Broad incumbents

• Meow Wolf: Immersive art experience company creating large-scale interactive installations and ARGs (e.g., House of Eternal Return, Omega Mart). Comparable to The Mystery League's ARG products like Pilcrow Bar and Hanukkah LOL but operating at a much larger scale and as a fixed-installation rather than service business.
• Sleep No More / Punchdrunk: Immersive theater production company behind Sleep No More and other large-scale narrative experiences. The Mystery League's collaboration with The House Theatre of Chicago on The Last Defender reflects a similar spirit of immersive theatrical-puzzle hybrids, though Punchdrunk operates at a much larger production scale.
