Mo Fang Heavy Industries LLC is a boutique production studio focused on building custom electronic props and effects for escape rooms and other interactive entertainment experiences.  With over ten years of experience in specialty hardware and software design for puzzles, we are equipped with the skills and expertise to help you turn your dream into reality.

Unlike some suppliers, who sell a set of cookie-cutter prefabricated props, every project for us is a bespoke engineering effort.  Whether you are looking for a turnkey start-to-finish fabrication or just a little extra help debugging a tricky problem with your Arduino firmware, we’ll help you finish your project on time and within your budget.

We’re also deeply experienced – as long-time veterans of the vibrant Seattle puzzling community, we’ve designed and built both electronic and traditional puzzles for a wide range of events, including escape rooms, Puzzle Hunts and The Game.  In addition to offering engineering and fabrication services, we’d also love to support you as you design, test, and refine the puzzle content for your next project.

We encourage you to review our portfolio, follow our blog where we cover topics of interest to escape room builders – and, most importantly, to get in touch with us if you’d like to discuss a potential collaboration on your next project!
