Zen and the Art of Fitting Too Many People in a Train

This puzzle was inspired by the Tokyo metro and the unique daily scene of commuters being carefully packed into the trains — sometimes even with the help of attendants whose job is to make sure the doors can close. That sense of organized chaos, precision, and calm under pressure became the spirit behind this design.

The puzzle begins with a small Sequential Discovery challenge and, once solved, transitions into a Packing puzzle where the goal is to fit 11 little figures inside the train wagon and manage to close the door completely. It captures both the mechanical curiosity and playful frustration of finding that perfect fit — just like rush hour in Tokyo.

Each puzzle comes wrapped in a fabric inspired by the traditional Japanese furoshiki, the elegant wrapping cloth used in Japan for centuries to carry gifts and personal items. 
It adds a touch of authenticity and makes the unboxing experience feel uniquely connected to its cultural inspiration.

The train wagon measures approximately 130 × 78 × 45 mm, and I’m attaching a few images so you can get a better sense of its look and construction.

The puzzle was created to be an exchange puzzle at the International Puzzle Party (IPP42), which was held in Tokyo in  2025.  Designed by Jordi Gallen and produced by Filarte 3D.
