“Sandy designed an absolutely unforgettable experience for us that worked within the overall plans for the day, while providing us with hours of entertainment and an absolutely amazing gift reveal for the birthday boy.

Remote team-building

Where Trivia Meets Mystery

Our live trivia & puzzle games fix what’s broken about completely remote events.

Asynchronous hunts

For groups who want a long-term game, we can build a private ARG (alternate reality game). We build you and your group a dedicated website where teams log in to see the puzzles, which appear every few days. Teams of employees join forces and work together to solve them. The site shows a leaderboard and lets teams request hints when they get stuck. These games are entirely customizable in theme and difficulty, and they can easily scale up in duration and player size.

Thank you Mystery League for helping us put on a fantastic virtual event! This wasn't “just another trivia event”. The puzzles were innovative, and the gamified virtual space added a really fun interactive and social element that our team really enjoyed. Sandy was a great host and organiser, helping us to set up a formal presentation in the virtual space before segueing into the game.  We also really appreciated how he adapted the puzzles for our three different timezone sessions, making sure the humour and trivia was inclusive for each region.  We had a blast! — Maeve Lander

Destination games

These site-specific games take 3+ hours for teams of 3-5 people. We can stage any of these for you, or we can design something entirely new.

And more...

For teams looking to explore a new place, we can build games in your neighborhood, wherever you live. Get in touch to discuss.

“Sandy is a puzzle genius and fountain of creativity, as well as a technical wizard. He worked closely with our marketing team to understand our company brand and understand our goals of the virtual puzzle event. He created a custom 5-part puzzle game that was just hard enough (but not too hard) to evoke the spirit of problem solving and competition. As a result, the event was a huge success – bringing together employees and clients from all across the US. As months go by, it’s an event people still talk about fondly.” — Jamie Jansen

Why hire us

Our games are crafted adventures

Each game unfolds into a carefully designed mystery where teams work together, discovering clues hidden within artwork, stories, and artifacts. Using deductive reasoning and creative thinking, players piece together solutions that advance the story.

Think of that electric moment when you finally crack a challenging problem. Now imagine experiencing that thrill again and again over two hours of play. Our games blend the satisfaction of breaking codes, the intrigue of a mystery novel, and the pure energy of childhood games into something entirely unique.

Every puzzle is thoughtfully designed to welcome both experienced and casual players. Teams might find themselves:

But what sets our games apart is the storytelling. Whether you're tracking down a criminal, hunting for treasure, or selecting Earth's next superhero, every puzzle advances a narrative that keeps teams fully immersed in their mission.

Elegance in Puzzles hosted by David Spira & Peih-Gee Law Sandy Weisz joins us on the podcast to talk about designing for elegance. As he explains, elegance in puzzles is when the puzzle “scaffolding” is woven into everything, from the theme, to the puzzle mechanic, to the illustrations, to the flavor text. He also tells us about some of the crazy puzzles he’s designed.
