Description
Duct 23 – Intermediate Packing Puzzle
Duct 23 is an acrylic packing puzzle designed and produced by Yuu Asaka. The objective is to fit all 23 acrylic pieces into the duct-shaped frame.
Instead of a standard rectangular tray, Duct 23 uses a winding, pipeline-like outline that changes how the pieces interact. The unusual frame shape creates channels, turns, and tight spaces that make each placement matter.
With its clean acrylic construction and approachable but thoughtful challenge, Duct 23 is a satisfying choice for solvers who enjoy Asaka’s clever spatial ideas without an overly punishing solve.
