I'm making a video game which has some basic cryptography as a main base for puzzle design. I'm hoping players will get great puzzle challenge and learn a few cryptography concepts through playing the game.
- Can you suggest some of interesting areas of cryptography that would be interesting/fun/easy to learn and understand that I could use as a game mechanic?
- Are there any instances of a single thing that are fun/interesting/unique and could be used as a puzzle?
All of these concept are masked, so that player with no experience in cryptography will ever make a connection. Some areas that are already included are basics in substitution and transposition (Caesar, Pigpen, Rail Fence, Grille...). For example of puzzle design: Grid Grille puzzle was modified in such a way that other shapes are used instead of a square, most notably 4 triangles in 1 triangle.
