Is it possible to create a crossword game based on skritter's word list?
I found python code for a crossword generator and was thinking of testing it to generate a pdf with crosswords using my skritter's last 30 failed words as a source. Could there be a webservice to get the 30 chars list or something like that?

I'm not sure how well that would work given that you're quite likely not too have many shared characters in the most recent mistakes. Even if you did unless you have some longer words in your lists then it's going to be tricky to make a crossword. Imagine 那么, 这么, and 圭亚那 - they don't fit together and it's just three words. Might be better slightly if you allow words to go backwards, but makes the coding and the crossword a bit harder.

You do have a point. I understand that crosswords work a lot better when there is a little number of different characters (like the english alfabet). I just aim to make a proof of concept that i can use the stats from skritter. Maybe to find the words in a character soup would be a better game.
