Create Caesar Cipher Puzzles
Encode hidden messages in Caesar cipher for scavenger hunts, escape rooms, and puzzle challenges.
Shifts each letter by 13. Self-inverse — applying it twice returns the original.
Puzzles tips
Choose a shift of 3 (the original Caesar shift) for classic puzzle design. Players who know history will try 3 first.
For harder puzzles, use a shift that doesn't have an obvious mnemonic. Shift 7 or 17 are harder to guess than 1, 3, or 13.
Frequency analysis: in English, E is the most common letter. If you see lots of H in the ciphertext, the shift might be 3 (E+3=H).
For escape rooms, hide the shift number in a visual clue. A clock showing 7 o'clock is the key to a shift-7 cipher.
