Cardinal Chains app for iPhone and iPad

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.
