Math is breaking. Space and time are fracturing. Someone or something is erasing numbers, rewriting equations, and opening a dreaded “ArithmeRift” in Seattle’s Pacific Science Center.
Agents of the Situationally Uncertain Mathematics Mitigation (SUMM) Division are trying to contain the Fracture and save math. But they need help from expendables volunteers. Like you! FRACTURE is an interactive math horror experience – part haunted house, part escape room, all live theater, and entirely SCARY. Suitable for anyone with a 3rd-grade grasp of math or more.
Explorations into the FRACTURE will commence from Thursday, October 15 through Sunday, October 25, 2026. Before 7pm expeditions will be slightly less frightening than the later “after dark" versions. Groups of fifteen will enter every fifteen minutes. Would you like to join the team?

Advanced paid tickets recommended. Room for walkups is always available. To join up, just show up!
The FRACTURE! is being contained for the time being with the reinforcement efforts of the following approved organizations.
MathHappens explores ideas, options, strategies and partnerships to bring math into community conversations across the United States.
Matheatre creates live theatre that tells stories to inspire excitement about math and science.
The FRACTURE is located in the Seattle Center at the Pacific Science Center. Visit pacificsciencecenter.org for trasportation and parking information.
