example:

"cheat2 svuicmnd 0" - You'd run on this input if you had the tiles "svuicmnd", zero wild tiles, and you wanted to see what tiles you could play off of to play all your tiles for the bonus. Click submit and you'll see that if there's an 's' on the board then you can go out!! So click on the 's' link, and cheat1 will be run, giving the word you can create.

another example:

"cheat sdfgioa 1" - Suppose the game just started with you going first, and you're dealt the tiles "sdfgioa" and a wild tile. Running on this input will give you a list of all possible words you can create.
