CipherStreet is a story-driven puzzle game where every level is a real cryptographic cipher - from Caesar shifts to RSA public keys - wrapped in a cold-war spy thriller. Intercept encoded messages. Decode them with on-screen tools you discover, not tutorials you sit through. Unlock fragments of a decades-spanning conspiracy with every cipher you crack. By the end of ten chapters you'll have genuinely internalised the foundations of modern cryptography - roughly the first four weeks of a university course — without a single lecture. THE STORY A defector known only as The Architect has built a private intelligence network hidden inside ever more sophisticated ciphers. Your handler, Agent Kovács, sends each intercept with minimal context and maximum urgency. A mole. A missing codebook. A name that keeps reappearing across fifty years. Crack the codes before dawn.
