About this game

Calm Cryptogram is a relaxing substitution-cipher word puzzle built around memorable English quotations.

Each puzzle replaces every letter with a different symbol. Use patterns, short words, and your intuition to reveal the quote one letter at a time. Take your time, make a guess, and use a hint when you need a nudge.

Features:
• Curated English quote puzzles
• Fair substitution-cipher gameplay
• Helpful hints without interrupting the puzzle
• Difficulty that grows with each fresh quote
• Progress and settings stay on your device
• No account required
• Optional one-time purchase to remove ads

Calm Cryptogram keeps advertisements out of the puzzle itself.
Decode thoughtful English quotes one letter at a time.
