John Voorhees, MacStories:
Knotwords is a deceptively simple new game from Zach Gage and Jack Schlessinger that combines elements of multiple word and logic puzzles into a unique, fun experience.
Each puzzle is composed of a set of squares that are divided into sections. Letters in the corner of a section establish which letters can be placed in that section of the puzzle. The goal is to arrange the letters, so they spell words vertically and horizontally throughout the puzzle. If that sounds simple, it is, but like any good game, just because the rules are easy to grasp doesn’t mean the game itself is easy.
This game is easy to figure out and often maddening to actually do — a perfect combination, in my world. Only one knock: the developers describe it as “minimal” in the App Store description, but it is nearly a gigabyte large. I wish it were as lightweight and blissful as it feels.
Good game, and not too expensive, either: free to download, then a couple of pricing tiers that get you more puzzles and a trickier game.
