As a seasoned enthusiast of building blocks, John Luo identified a gap in the market: the available options were either too basic, offering limited creativity with rough constructions, or too rigid, with high-structure accessories that constrained imagination. He envisioned a system that would allow for both freeform and lifelike creations.

The epiphany came while helping his son with math geometry problems. To make the abstract concepts more tangible, John used objects with similar geometric shapes. He demonstrated how eight small cubes could form a larger cube and how two equal right triangles could combine into a larger right triangle. This hands-on approach not only helped his son grasp the concepts but also sparked an idea in John—a system of geometric blocks that could replicate the shapes found in everyday life.

In 2013, after four years of development, the first series of Pungrow geometric building blocks were introduced, with a side length of 2cm. Drawing inspiration from ancient Chinese architecture, John's design team refined the mortise and tenon structure, adjusting the number and shape of the joints for a more secure and user-friendly connection. The initial release included three shapes—square, triangle, and circular sector—in eight colors, all in the 2cm size.

The Pungrow Geometric Building Blocks have since evolved, with an expanding palette of colors, shapes, and sizes, along with a variety of accessories. These enhancements aim to offer greater realism and versatility in construction. Despite the growing diversity within the Pungrow block family, their distinctive 6-sided mortise and tenon structure remains a hallmark, easily recognizable among other building blocks.
