How CipherForge Play works

Your privacy comes first

• No account, ever. You just open the page and play.
• No ads and no tracking. There are no third-party trackers on this page.
• Nothing leaves your device. Your XP, level, and day-streak are saved only in this browser (localStorage). Clearing your browser data resets them — and that's the only place they ever lived.

What you can do

• Cipher Workbench — a free lab: encode and decode with Caesar, Atbash, Vigenère, and Rail-Fence, with a spinning cipher wheel and a live letter-fingerprint chart.
• Code-Breaking Arena — crack Caesar messages using frequency analysis (the letter E is your best friend).
• Cipher Detective — identify which cipher made a mystery message from its fingerprint.
• Concepts — 16 short question kits, from secret-code basics up to cybersecurity.

How it helps you learn

You always try first — a hint only appears after your first attempt, because working it out yourself is how it sticks. A wrong answer never scolds you; it explains what happened and shows the way. This is the same "figure-it-out" approach the CipherForge app uses.
