Cipher Command vs Cipher Attack

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.

Six ways to play. One goal: crack the code. From a quick daily challenge to live 1v1 duels — there's a mode for every agent. Daily Operation A new code every day, the same for every player worldwide. Compete on the global leaderboard and compare your performance. 1 challenge / day Against the Clock 120 seconds on the clock. Crack as many codes as possible before time runs out — every second counts in the global rankings. Infinite Loop No time limit. Keep cracking codes and build your longest streak ever. How far can you go? 1v1 Duel Generate a challenge code and send it to a friend. Both crack the same code , whoever uses fewer attempts and time wins. Async friend duel Online Match Get matched against a random opponent in real time. No friends needed — just your wits. A bot steps in if no one is available. Live ranked match and much more. How to Play Simple rules. 1. The Secret Code A random 4-digit code is generated. No repeating digits. The first digit is never 0. 2. Make a Guess Enter your 4-digit guess. You have 10 attempts to crack the code. 3. Read the Feedback + = correct digit in the right position. − = correct digit, wrong position. 4. Use Power-ups You can reveals a hidden digit. Or hit to button to grant 1 extra attempt. Both require watching a short ad.
