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.

| A | .png) | B | .png) | C | .png) |
|---|---|---|---|---|---|
| D | .png) | E | .png) | F | .png) |
| G | .png) | H | .png) | I | .png) |
| J | .png) | K | .png) | L | .png) |
| M | .png) | N | .png) | O | .png) |
| P | .png) | Q | .png) | R | .png) |

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.
