Siren — Traffic Jam Puzzle

Siren is a traffic jam puzzle with a rescue at its heart. An ambulance is boxed in by rush-hour traffic, and the clock is a heartbeat. Your job: tap the cars to clear a path.

Every vehicle faces one way and only drives forward. Tap a car and it pulls forward — off the board if the lane is clear, or up against the next car if it isn't. No dragging, no reversing. Read the jam, tap in the right order, and open the road before time runs out.

The ambulance's route often bends, so the traffic jam you have to solve is never just a straight line. Clear the crossers, work the chains, and watch the corridor open.

HOW TO PLAY
• Tap a car to drive it forward and out of the way.
• Clear the ambulance's path — corners and all.
• Beat the heartbeat timer, or switch on Relaxed mode for no clock at all.

FEATURES
• 80 hand-tuned levels across four rainy-night districts.
• A daily challenge on the toughest boards — for experts only.
• Cars, vans, buses, trucks and trams to unjam.
• Relaxed mode, colour-safe lights and reduce-motion options.
• Collectible ambulance skins and city themes.
• Plays fully offline. No account, no sign-up.

Siren is free to play. It shows ads and offers a few optional one-time purchases — remove ads, cosmetic skins and themes — but the whole game, all 80 rescues, is free. Progress is never for sale.

Clear the jam. Make the rescue.
