Insert letters into a word in the grid to extend it, pushing pre-placed letters to be later.

? can stand for any letter, but must be the same letter throughout solving.

For the larger grids, letters are broken into sets; sets should be added one at a time from top to bottom, with all the letters of a set going to the same word but sets themselves potentially going to different words.

Every word in the grid must always be valid.
