Astronigma: Star Logic Puzzle

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.
