Knotwords+ is a minimal and elegant logic puzzle — with words. The rules are simple: arrange the letters in each section so every word is valid, across and down. Each puzzle may seem difficult at first — but like all my favorite newspaper puzzles, it gets easier as you progress. Each step guides you naturally towards the solution. This is the kind of game I've been trying to make my whole career — I'm amazed Jack and I discovered this design. We hope you like it.
