Description by Francois Van Malleghem Written by the developer, not by AppBrain. Click to read.
Cipher Grid is a daily puzzle game where you decode real encrypted messages using actual historical ciphers. Each puzzle is a quote hidden behind a different code. Your job is to figure out the letters and reveal it.
DAILY PUZZLE
One new challenge every day. Each day uses a different cipher and difficulty, so no two days feel the same.
18 CIPHERS TO DECODE
Caesar. Atbash. ROT13. Morse. Vigenère. Playfair. Semaphore. Maritime Flags. And more. Each one is a real encryption method used throughout history — from ancient scribes to World War spies to modern radio operators.
LEARN AS YOU PLAY
Built-in lessons explain every cipher from the ground up. No prior knowledge needed. Start as a complete beginner and work your way to mastering techniques used by real cryptographers.
ENCRYPT AND DECRYPT
A full toolkit covering 22 ciphers, free for everyone. Includes a working Enigma I simulator with configurable rotors, reflector, ring settings, and plugboard, plus the Hill matrix cipher.
ZODIAC CHALLENGE
A separate set of hand-picked puzzles to solve at your own pace. Free.
PRO
