## What is Quiet Logic?

Quiet Logic is a calm Zebra-style deduction game for people who like logic puzzles without timers, pressure, or noisy effects.

What you get:
• 200 handcrafted logic puzzles from easy to expert
• Daily puzzle for a quiet routine
• Zebra / Einstein-style clue chains
• Gentle hints without harsh failure states
• Local progress tracking
• Optional cozy soundscapes
• Offline prebaked puzzle library

Quiet Logic Pro unlocks the full puzzle library beyond the free starter set. Daily puzzles remain free.
