Every letter of the alphabet has been substituted with a different letter. The substitution is the same for all clues.
You can solve one letter at a time: e.g. if 'I' was used to represent 'Q,' you would type 'I=Q.' You may also solve a whole answer at once: e.g. If you figured out that #17 FRY = PAN then you can type 'FRY=PAN' to have the whole answer appear. Or you can use the number and type '17=PAN.'
