Serial Squares NTC is a refined wooden packing puzzle designed by Lucie Pauwels and produced by Pelikan Puzzles. Twenty square pieces in three distinct colors must be arranged within a precise 10 × 10 tray, but the color-placement rule makes the challenge far more demanding than it first appears.
The objective is to fill the tray while ensuring that pieces of the same color never touch, either along an edge or at a corner. The set includes squares in four sizes, from large 4 × 4 pieces down to individual 1 × 1 squares. With only two valid solutions, every placement carries real weight.
Serial Squares NTC blends clean geometric design with a deceptively deep logic constraint. It is ideal for puzzlers who enjoy working through limited possibilities, balancing color and shape, and earning a precise final arrangement rather than relying on simple trial and error.
