## What is Harbor Grid?

The sleeping harbor needs your touch.

Tap city blocks to rotate their brass circuits, then guide cyan power from the substation to every landmark. Watch warm windows illuminate as the miniature city comes back to life.

• 60 distinct puzzle maps across five 12-mission campaigns
• Changing rules: priority routes, storm-locked tiles, medical emergencies, and fuse limits
• Focused one-to-three-minute play sessions
• Three-star grades that reward efficient solutions
• Premium miniature art with distinctive substations and landmarks
• Local-first play with no account or required connection
• Korean, English, Japanese, Spanish, and German
• Adjustable sound, haptics, language, and theme

Free play includes five hearts. A failed mission uses one and a heart recharges every 15 minutes. Optional rewarded ads grant one heart; a one-time Premium purchase unlocks unlimited hearts and hints with no ads.
