The basic idea of this is very simple, and I am surprised that no one else seems to have done this before. Basically, you can enter any cryptogram you wish. You don’t have to purchase them from anybody. Once you enter them, you can have two wheels. You can select whatever letter you wish to in the puzzle and align that with any letter you wish to substitute on the other wheel. This will then replace those letters in your solution problem. Eventually, hopefully, you will solve it correctly and see the correct quote. If you make a mistake, you can resend one letter or all of the letters. This is really the only tool you need to solve these things. I am surprised it’s a sofa for free because this is a cryptogram solvers dream.
