A browser-based cipher puzzle game where you intercept and decrypt encrytped messages, progressing through increasingly complex ciphers.
You play as a cryptanalyst who has intercepted a series of encrytped transmissions. Each level introduces a new type of cipher, from simple reverse text to Viginere and XOR. Decrypt all messages to prove your skills.
No installs, no dependencies, just open the link and play.
- 🔄 10 cipher levels - Reverse, Caesar, Atbash, Binary, Morse, Base64, Hex, Viginere, XOR, and a final combo challenge
- 💡 Hint system - stuck? use hints, but they cost you points
- ⏱️ Score tracking - earn points based on speed and accuracy
- 🧠 Educational - learn real cryptography concepts while playing
The game is built with vanilla HTML, CSS, and JavaScript
Each cipher has its own encode() function that transforms a plaintext message. The player sees only the encoded output and must figure out the original. Ciphers range from trivial (reverse the string) to non-trivial (XOR with an unknown key, where the player must deduce the key from context).
The scoring system rewards fast solves and penalizes hint usage, creating a tradeoff between speed and independence.
