A team of ten domino artists has set a new Guinness World Record for the most dominoes toppled in a three-dimensional pyramid, bringing down 29,193 tiles in a single chain reaction at a gym in Garden City, Michigan, on June 20.

Guinness World Records has officially certified the achievement, which was set by the FALLDOWN Domino Team led by Steven Price of Sprice Machines as part of a larger installation that incorporated no fewer than 123,456 dominoes in total.

The feat, documented in a YouTube video titled “123,456 Dominoes SUPERSIZED — FALLDOWN 2026,” has attracted widespread attention online for the scale and precision of its construction

Price has held four domino-related Guinness World Records previously and has served as a judge on Fox’s competition show Domino Masters. He holds a mechanical engineering degree, a background that is evident in the structural ambition of this project.

Building a 35×35 pyramid without triggering it

The three-dimensional pyramid that forms the centerpiece of the record sits on a base of 35 by 35 dominoes and rises in layers to a pointed apex. Constructing a 3D pyramid of this scale requires a level of precision that flat domino runs do not — every tile must be positioned accurately while the structure beneath it remains stable, and a single mistimed touch anywhere in the grid can bring the entire build crashing down prematurely.

The FALLDOWN team, which includes Michael Fantauzzo, Matt VanVleck, Gabe Dean, Alex Koops, Derek Koops, Stephan Burton, Brady Dolan, Evan Voeltner, and Aaron Bimrah alongside Price, spent multiple days installing the complete setup.

A world built from supersized everyday objects

The pyramid was not the only engineering feat in the room. The team built a themed installation around 123,456 dominoes arranged into giant versions of ordinary objects — enormous paperclips, oversized friendship bracelets, massive bonsai trees, school supplies and a rubber duck that appears mid-sequence.

These elements fed into a series of Rube Goldberg-style chain reactions that snaked through the entire installation before converging on the pyramid, making the final topple a product of everything that came before it.

Guinness required a traditional domino-to-domino start

The team had originally planned to use a special mechanical trigger to bring the pyramid down. Guinness World Records rejected the approach: to qualify for an official record, the entire chain must begin with a conventional domino touching the next in sequence, with no external mechanism initiating the fall. The team revised their plans accordingly, and the record-setting run began exactly as the rules required.

Price’s fifth Guinness record in domino art

The FALLDOWN record is Steven Price’s fifth Guinness certification in domino-related categories. His prior titles include the largest domino circle field, the longest domino wall, and the largest two-dimensional pyramid. Price first gained wider recognition as a 22-year-old when his Incredible Science Machine project, which involved 250,000 domino tiles, set records and went viral.

His YouTube channel, Sprice Machines, includes videos with over 30 million views, with the Lemonade Machine — a chain reaction that travels through an entire house to serve lemonade — among the most-watched.
