For many of us, 2020 turned out to be extremely unpredictable, atypical and mysteriously “encrypted”. We wish 2021 to be more predictable, happy and “deciphered”. We wish you to choose your code and algorithm for it. The leaflet hides three groups of information, encrypted in three different ways. The first is good wishes with a simple decipherment. Second. Wishes can be seen through the windows on the first page of the card. The third. The text can be deciphered by using the algorithm for calculating the lines (a, b, c, d …) and the sequence number of the letter (1, 2, 3, 4 …) in the corresponding line.
