Show HN: Motplot is a crossword but it plays like Sudoku

My family plays a lot of word games, some are board-game style and of course we all love the NY-Times catalog of puzzles. The idea for this game came to me when I played bananagrams, and lost, after having binged way too much sudoku earlier in the day.

I became obsessed with the idea of making this work, and it was way harder than I expected. The journey took me into the depths of confusability graphs and zero error capacity in information theory. I might write a post about it some day.
