Ninety seconds from the game itself: a boxed-in ambulance, the three calls, and the road from Downtown to Frontline Valley.

Rush hour. The ambulance is boxed in.

  1. Rush hour. The parking lot is packed solid, and there's an ambulance stuck in the middle.
  2. It can't turn. It can only drive forward, or back.
  3. Tap a car and it drives the way its arrow points.
  4. Pick the right order, clear one lane, and the ambulance is free.
  5. Race an ambulance to the hospital, a fire engine to the fire, and a police car to the bank alarm.
  6. Drive them through downtown, the docks, snowy hills and farm country.
  7. A hundred and sixty-plus levels, and the jams keep getting bigger.
  8. Lower the drawbridge. Flip the lights. When a wreck won't budge, call the tow truck.
  9. Out on the frontline, even the tanks are stuck in traffic.
  10. Siren Jam. Clear the way.

How a jam works

  1. It's boxed in

    The ambulance is parked in the middle of the jam with cars on every side. It can't turn, so it can only leave straight ahead or straight back.

  2. Tap a car

    A car drives off only the way its arrow points, round the one-way ring road and out. If anything is in the way it honks and stays put, the cars in the way flash red, and the tap costs no move.

  3. Find the order

    Clear one of the two lanes, ahead or behind. One is usually cheaper, and on later levels the move limit leaves no room for the other.

  4. Race out

    Finish within the move limit to win. The faster you finish, the more stars you get, up to three. Then the crew races to the rescue.

  1. Level 14, Downtown: the ambulance boxed in on every side, the hospital at the top of the street.
    Downtown, level 14
  2. Level 9, Downtown: a police car boxed in by rows of cars outside the city bank, an arrow on every car.
    Downtown, level 9
  3. Level 46, Harbor City: a raised drawbridge blocks the road to the hospital, and a speech bubble asks you to tap it.

  • Traffic Light turns every light green for 8 seconds.

  • Hint shows the next good move.

  • Freeze stops the clock for 10 seconds.

What gets in the way

  • Traffic lights: one tap swaps them all

Quick answers

What is Siren Jam?

Siren Jam: Parking Puzzle is a free puzzle game for Android and iPhone. In every level an emergency vehicle (an ambulance, a fire engine or a police car) is parked in a jammed car park and boxed in on every side.

You tap the other cars so they drive away, in the right order, until the emergency vehicle has a clear lane and can race to the hospital, the fire or the bank alarm.

Is it free? Can I buy anything?

Siren Jam is free, and there is nothing to buy: no coin packs, no subscriptions and no paid levels.

You earn coins by clearing levels (more for new stars), from the daily gift and, if you choose, by watching a short ad. Coins buy power-ups, and five extra moves when you run out.

Are there ads?

Siren Jam shows an ad only when you ask for one. In the shop, or when you are out of moves and short of coins, you can tap Watch to see a short ad for 40 coins, up to five times a day. There are no ads during a level and no banner ads.

When did it come out, and where can I get it?

Siren Jam is out now, free, on Google Play and the App Store. It came out on Google Play on 30 September 2026 and on the App Store on 8 October 2026.

On the App Store it is available in 174 countries and regions: every App Store country except mainland China. The buttons at the top and bottom of this site go straight to the store pages.
