# Tic-Tac-Toe Cipher

## Answers to Questions (FAQ)

### How to encrypt using Tic-Tac-Toe cipher?

The Tic-Tac-Toe code uses the 3x3 grid of the game of the same name (also known as OXO grid). The grid is composed of 2 vertical lines and 2 horizontal lines delimiting 9 distinct spaces, ie. the character # (sharp) but in bigger.

In this grid are written the first 9 letters of the alphabet, then with crosses, the next 9, and with circles the last 8.

Example:

Each letter is then symbolized by a symbol characterizing its location in the grid: 2 to 4 lines to indicate the position of the box and a point to indicate the position of the letter.

### How to decrypt Tic-Tac-Toe cipher?

Decryption can be done visually via a drawing of the grid with paper and a pencil, replacing each symbol with the corresponding letter.

Example: is translated TICTACTOE

### How to recognize a Tic-Tac-Toe ciphertext?

The symbols are very similar and must be reminiscent of the ridge grid, right angles, 2 to 4 perpendicular lines accompanied by a single point having 3 possible positions (left, center, right).

The symbols look like the Pigpen cipher which is similar.
