Cardinal chains is a minimalist puzzle game centering on the concept of non-decreasing sequences.
Each puzzle begins with a monochrome grid of numbers, plus a few colored cells marked with an “X”. Starting at these cells, you must link up numbers in non-decreasing order until the whole grid is filled with color. This game was made by Daniel Nora and is playable on all platforms.
