Guess the five-letter word. Type a real word and press Enter. The paper
marks each letter: reversed (white on green) is right in the right place,
ringed is in the word but somewhere else, struck is not in the word
at all.
The case remembers. Letters you have already placed stay marked in the
compositor's case below the grid, and a mark never gets worse than the best you
have earned.
Run out and the edition goes to press. The word is printed either way,
and nothing is held against you.
One word a day. Your board and your clock are saved, so you can put the
paper down and pick it up later.
