- Take these characters and insert them in between the 2nd to last and last character of the Solitaire Key.
- Count off the number of characters on the left equal to the alphabetic position (A1Z26) of the first character of the Solitaire Key.
- Take note of the character AFTER the characters you counted in the Solitaire Key.
- Take the sum of the alphabetic positions (A1Z26) of the Nth encrypted letter and the character you got from the previous step.
- If the result is above 26, subtract 26 until the number is between 1 - 26. Turn the resulting number back into a letter.
- Do this for each letter of the encrypted word to get your decrypted word.
