Crypto Logic

is a substitution cipher in which one letter stands for another.

The top pane is the encrypted quote; the pane below it is your work area.

To start, press Set. A keyboard appears. Select the letter you wish to substitute for.

Press Equals. The keyboard again appears. Select the letter you wish to substitute.

The text in the work area shows the change; the key panel on the right shows your substitutions.
