## What is Cipher Grid?

A new secret message to crack. Every single day.

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
Unlock unlimited practice puzzles and Secure Message — public-key encrypted messages and photos that only the intended recipient can decrypt. Keys live on your device. Share the envelope as text or QR code, no servers involved. Every future feature added to the app is included.

PRIVACY FIRST
No accounts. No analytics. No tracking. No ads. Everything stays on your device.

Available in English, French, German, Dutch, and Chinese.
