Added an alphabet reference strip to help with cipher solving — tap "A – Z" to expand a compact two-row guide. For Atbash ciphers, the strip shows forward and reverse alphabets paired together for instant visual mapping. Variable Caesar puzzles now show "Starting Shift" to clarify that the offset increases with each letter. Small quality-of-life improvements to help you focus on cracking the code, not counting on your fingers.

Agent, our decryption tools have been upgraded. Reverse transmissions, multi-step codes, and mixed ciphers now use an intuitive tap-to-decode grid — tap any letter to fill it in, tap again to fix mistakes. Every position lights up green or red after submission so you can see exactly where you went wrong. Some transmissions that were previously unsolvable have been repaired. Good luck out there.

New interactive solving experience! Tap any encrypted letter to map your guess — all matching letters fill in automatically. See your decryption progress at a glance as you crack each cipher.
