Cardinal Chains by Daniel Nora

– 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.

• 500 unique, carefully handcrafted puzzles of varying difficulty, each with a single solution
• Beautiful, lengthy chill-out soundtrack created by professional artists
• Minimalist, elegant design without timers, scores or other hassles
• Several built-in color themes, including colorblind options. Or…
• …make your own color themes – right from within the game!
