Making your own secret code puzzle to have friends and family solve is one way to pass the time. There are various ways of going about creating a secret code puzzle, the easiest of which is by switching the order of the alphabet in order to create a secret code.

Write out the first 13 letters of the alphabet (A through M) on a sheet of paper.

Write out the second 13 letters of the alphabet (N through Z) directly below the first 13 but in reverse order. These two rows of letters will be your puzzle’s key. The way you read the key is that each letter on the first row now represents the letter on the second row, and each letter on the second row represents the letter on the first row. So A=Z and Z=A.

Write out a message which will be the secret code puzzle. For example, you can write a famous quote, the lyrics to a popular song, or whatever you want.

Write the same message using your new code on a separate piece of paper. For example, if you wrote “I think, therefore I am,” then the secret code version would read “R gsrmp, gsvivuliv R zn.”

Write a clue on the same sheet of paper on which you wrote the secret code puzzle. For example, you could write I=R and E=V. This is important because in order for the puzzle to be solvable, there has to be a clue. When you are done with this, give the puzzle to a friend or family member to solve.
