Lumen District: Circuit Puzzle

Bring the night to life, one circuit at a time.

Tap tiles to rotate their wires. Connect every light to the fixed + power station with no open ends. Connected paths glow mint green.

• 120 campaign circuits across 12 districts
• Boards grow from 3×3 to 6×6
• A daily circuit based on the UTC date
• Up to three stars for solving within the move target
• Continue unfinished circuits after closing the app
• No timer or lives; restart freely

One hint per circuit is free. Watch an optional rewarded ad for more hints. Interstitial ads appear only at natural breaks after an initial play period.

The puzzle works offline; ads need a connection. Progress is stored on your device.
