To substitute letters, elect the letter from the cryptogram from the top set of letters and the letter you think it represents from the bottom set.  You can also do it vice versa.  Each time you do this, the corresponding letters will show up on the puzzle.  You can also change letters back to dashes.  To start over, just click on the “Restart” button.

The chart under the cryptogram tells you how you’ve mapped each letter so far, and it tells you the frequency of each letter in the cryptogram.
