The dossier
A patient feat, witnessed in full.
Set inside a converted textile mill, the 1.4-kilometre spiral took 31 hours to lay and 22 minutes to fall. The panel reviewed three independent camera angles, two ambient audio tracks, and a stack of timestamped notes from the four observers in attendance. The cascade clock began at 14:22:00 local time on the day of the attempt and ended at 14:44:09.
Adjudication centred on whether the spiral met the published rule of measure for an indoor cascade — specifically, whether each tile contacted the next within the rule’s tolerance, and whether the cascade completed without manual intervention. On both counts: yes.
What the rule says
Per SKL-DOM-001, an indoor domino spiral must be measured along its as-laid path with a calibrated wheel, completed in a single uninterrupted cascade, and witnessed by no fewer than three independent observers with sight of the start and end points.
In the holder’s words
“You can’t rush the corners. They’re where every spiral I’ve ever lost has died. I gave myself a half-hour break every six hours, drank a lot of tea, and tried not to think about the heating turning off overnight.”
