Crozzby is a hungry machine. He is fond of word lists. Huge or small. In every possible language. He accepts them in .csv format and eats his way all through your lists.
Let him work for you as long as you wish. You need a series of 365 crossword puzzles for daily consumption the whole year round? He’ll deliver them at your command. And he’ll keep track of the words already used in order to avoid using them again in the next crossword. He adapts the simplest of rules here: the longer the word, the longer he keeps it in memory. You wont see that 11-letter word again for the next two weeks, unless you tell him explicitly to do so.
