Answerback: Cipher Mystery

Febroine

About this game

At 03:14 your screen wakes up on its own. You pull the plug. It stays on.

Answerback is a story-driven cipher mystery and text adventure played on an old green terminal. A signal is reaching you, one fragment at a time, and you decode it by hand like a codebreaker: shift ciphers, Morse code, binary, a Vigenère key, a spectrogram, a telex you crack by letter frequency, a frequency you work out yourself, a guarded archive you slip through. Every word you recover changes what you understand about the night your father heard the same thing on his radio, and about the people who have been listening ever since.

If you like escape room puzzles, cryptograms, detective stories, conspiracy thrillers and interactive fiction where your choices matter, this one was made for you.

• 3 acts, 24 chapters, 50+ puzzles across more than twenty kinds
• 8 message fragments, 8 endings (one of them hidden), and one way to get caught early
• Choices that echo: lines you read later remember what you did before
• A decision map to replay any chapter you have reached and try the other road
• A daily transmission: a new short cipher every day, and a streak to keep
• Hints in three steps: the first nudge is always free, deeper ones cost a token you earn by playing
• Relaxed timers, adjustable text size and speed, reduce motion and screen-reader labels
• Plays fully offline, in English and Turkish, switchable at any time

No ads. Nothing to buy. No account. Your saves never leave your phone.

Headphones recommended.
