Get a random hand from a bag of scrabble tiles and try to input a word with the highest possible score, get a ranking based on how close you were to the highest scoring words Tiles are weighted so that you're guarenteed to get at least 2 wilds and no more than 4 -- making for a much fairer chance at finding fun words
Or if you want, you can just cheat. Input your own letters (?) for wilds/blanks and the program will give a list of all possible valid words, from highest to lowest score
