Siren Jam: Car Parking Puzzle

An ambulance, a fire engine or a police car is boxed in. Tap the other cars aside, unblock one straight lane, and this car parking puzzle lets it leave straight ahead.

The emergency unit can't turn. It gets out straight ahead or by backing straight out, so one of its two lanes has to be cleared. Tap a car and it pulls away in the direction of its arrow. Tap in the wrong order and it bumps into whatever is in the way. Work out who has to move first, open the lane, and watch the siren race off to the hospital, the fire or the bank alarm while the crowd cheers.

How it plays
• Tap a car to send it out along its arrow
• Clear the lane in front of or behind the trapped emergency unit
• Get it out inside the move limit, and respond fast for up to three stars
• Every level is checked by our solver, so every jam has a way out

160 levels in 8 worlds
Downtown, Maple Suburbs, Harbor City, Roadworks District, Snowy Heights, Festival Square, Sunny Farmland and Frontline Valley each bring 20 jams and their own twists: one-way ring roads, barricades you tap away, timed zebra crossings, traffic lights you switch, a drawbridge you lower and broken-down cars that need a tow. The jams grow from a gentle warm-up to lots packed with more than forty vehicles.

Power-ups for tight spots
• Tow Truck lifts a stubborn car straight out of the lot
• Traffic Light turns every signal green for a few seconds
• Hint shows you a good next move
• Freeze stops the response clock for ten seconds

A lively little town
People on the sidewalks chat about the jam, react to every honk and cheer when the unit arrives. Each world has its own neighborhood to look at while you think: a marina, a fairground, a frozen pond, farm fields with a working tractor and a toy army camp.
