Cipher Command

No ads, no timers. Crack real WWII ciphers — Caesar to Enigma — across 30+ historical missions. Free to start; unlock theaters once and keep them forever.

Step into the shoes of a Bletchley Park codebreaker. Cipher Command is an immersive puzzle game where you decrypt authentic World War II cipher messages using historical encryption techniques.

CRACK REAL CIPHERS Master seven historically accurate cipher systems — from the classic Caesar shift to the legendary Enigma machine. Each puzzle uses a real encryption method employed during wartime operations.

30+ HISTORICAL MISSIONS Decode intercepted messages spanning D-Day preparations, Pacific Theater intelligence, Eastern Front communications, and Cold War-era signals. Every mission is grounded in real historical events.

INTERACTIVE CIPHER WHEEL Spin the beautifully crafted Caesar dial to decrypt messages letter by letter. Tap individual cipher letters, rotate the wheel, and watch the plaintext emerge — no shortcuts, just pure codebreaking skill.

LEARN AS YOU PLAY Each mission briefing provides historical context about the operation, the cipher technique, and the stakes. The built-in Codex reference covers every cipher type with examples and history.

EARN YOUR RANK Progress from Unclassified to Most Secret difficulty levels. Collect achievement badges as you hone your cryptanalysis skills and rise through the ranks.

FAIR BY DESIGN No ads. No energy meters. No subscriptions. The opening missions are free, and each historical theater is a one-time purchase you keep forever.
