The main bank of five rotors was termed the cipher rotors (Army) or alphabet maze (Navy) and each rotor had 26 contacts. This assembly acted similarly to other rotor machines, such as the Enigma; when a plaintext letter was entered, a signal would enter one side of the bank and exit the other, denoting the ciphertext letter.
Because of this, maze generation is often approached as generating a random spanning tree. Loops, which can confound naive maze solvers, may be introduced by adding random edges to the result during the course of the algorithm. The animation shows the maze generation steps for a graph that is not on a rectangular grid.
The pigpen cipher uses graphical symbols assigned according to a key similar to the above diagram. [1]The pigpen cipher (alternatively referred to as the masonic cipher, Freemason's cipher, Rosicrucian cipher, Napoleon cipher, and tic-tac-toe cipher) [2] [3] is a geometric simple substitution cipher, which exchanges letters for symbols which are fragments of a grid.

Hints and the solution for today's Wordle on Tuesday, February 4.
An animation of creating a maze using a depth-first search maze generation algorithm, one of the simplest ways to generate a maze using a computer. Mazes generated in this manner have a low branching factor and contain many long corridors, which makes it good for generating mazes in video games .
Robot in a wooden maze. A maze-solving algorithm is an automated method for solving a maze.The random mouse, wall follower, Pledge, and Trémaux's algorithms are designed to be used inside the maze by a traveler with no prior knowledge of the maze, whereas the dead-end filling and shortest path algorithms are designed to be used by a person or computer program that can see the whole maze at once.
Example cryptogram. When decoded it reads: "Style and structure are the essence of a book; great ideas are hogwash." -Vladimir Nabokov. A cryptogram is a type of puzzle that consists of a short piece of encrypted text. [1]
