MetroSignalCommand

Metro Signal Command is an offline metro train dispatch puzzle for iPhone. You are the night-shift dispatcher for 50 world cities. From London Circle to Tokyo Ginza, from NYC 1 Train to Sydney Metro, you control the trains through the midnight low-traffic window. Keep them on time, respect speed limits, avoid collisions, and respond to faults. HOW TO PLAY - Tap a train to select it (yellow highlight). The first train is auto-selected at level start. - Tap the green + button to accelerate (+0.05 per tap, up to 2x base speed). - Tap the red brake button to decelerate (-0.05 per tap, down to 0.01). - Watch for speed-limit zones (yellow = warning, red = enforced). Trains auto-brake and lose 8 points if speeding; +2 points per second of safe passage (combo). - Manage multiple trains on the same line. If two trains get too close (under safe following distance), the rear train auto-brakes and loses 10 points. - When a fault hits (signal, door, crowd), tap Resolve Fault quickly — faster resolution means higher score. - Survive 60 seconds per level. Reach the star threshold (3 stars at 80, 2 stars at 60, 1 star at 40) to unlock the next city. 50 WORLD CITIES - Europe (L1-L15): London, Paris, Berlin, Moscow, Rome, Madrid, Lisbon, Athens, Warsaw, Prague, Vienna, Amsterdam, Stockholm, Oslo, Copenhagen - Asia (L16-L30): Istanbul, Tehran, Dubai, Riyadh, Karachi, Delhi, Bangkok, Singapore, Kuala Lumpur, Jakarta, Manila, Seoul, Tokyo, Beijing, Tel Aviv - Africa (L31-L36): Cairo, Lagos, Nairobi, Johannesburg, Casablanca, Addis Ababa - North America (L37-L44): New York, Toronto, Mexico City, Los Angeles, Chicago, Miami, Vancouver, San Francisco - South America + Oceania (L45-L50): Sao Paulo, Buenos Aires, Santiago, Lima, Bogota, Sydney SCALING DIFFICULTY Trains per level grow from 1 (L1-L10) to 2 (L11-L30), 3 (L31-L40), and 4 (L41-L50).
