I made this little word game just for fun yesterday:
Details for nerds: I load a dictionary of common words in U.S. English, and I group them into "anagram sets": words that are anagrams of each other. I pass the data into a React app that chooses a word for each round. The drag-and-drop doesn't work on mobile. If I could invest time in making it mobile friendly, I would probably incorporate react-dnd-touch-backend.
