Duct 23 - Level 5 - Yuu Asaka

Duct 23 – A Maze-Like Acrylic Packing Puzzle by Yuu Asaka

Step into Yuu Asaka’s signature brand of “looks easy… isn’t” with Duct 23, a beautifully crafted acrylic packing puzzle released on December 5, 2025. Unlike a standard rectangular tray, Duct 23 features a distinctive duct / pipeline-shaped frame—a winding, maze-like outline that adds a clever spatial twist and makes every placement decision matter.

The objective is simple: fit all 23 precision-cut acrylic pieces into the duct-shaped frame—no force, no bending, no gimmicks. But as you test configurations, you’ll feel the hallmark Asaka challenge: subtle interference, tight constraints, and that final layout that stays just out of reach… until it suddenly clicks into place with a satisfying “A-ha!”.
