## What is Astronigma?

Turn one lens, and its neighbors change with it. Solve relaxing 5×5 logic puzzles, rebuild your telescope, and reveal 120 constellations on a quiet cosmic journey.

HOW IT WORKS
Tap a lens to flip it and the four adjacent lenses. Plan each move and clear the grid within the move limit. Use Undo or Hint when you need a nudge—there is no timer inside the puzzle.

DISCOVER THE COSMOS
Solve puzzles to collect Light Shards. Spend them to align seven telescope lenses, reveal a new constellation, and add its illustrated story to your archive.

KEEP A DAILY RHYTHM
• Daily Challenge: complete five stages each day and work toward a monthly collectible reward
• Missions: finish easy, medium, and hard goals to earn milestone rewards
• Constellation archive: reveal and collect 120 constellations
• Practice: keep solving without rewards when you run out of Hearts

WHY PLAY ASTRONIGMA
• Simple cross-toggle rules with satisfying deduction
• Procedurally generated 5×5 boards with adaptive difficulty
• No puzzle timer—think at your own pace
• Core puzzles are playable offline
• Atmospheric space visuals and sound
• Hints and undo when you need them

Astronigma is made for fans of grid puzzles, brain teasers, calm logic games, and cosmic discovery.
