CAR PARKING JAM 3D
Car Parking Jam 3D is a sliding-block puzzle dressed up as a car park. The cars are parked nose to tail, one of them needs to reach the exit, and each car can only move forwards or backwards along its own lane. You slide the others out of the way until the path opens up.
If you've played the wooden block version of this, or any of the unblock-the-red-car puzzles, you know the idea. The 3D view doesn't change the rules, but it does make it easier to see which cars are actually blocking which, and the levels here are laid out well enough that most have a clean solution once you spot it.
The first batch of levels are warm-ups. After that they start filling the lot, adding long vehicles that take up more room, and putting the exit somewhere inconvenient. There's no timer, so a hard level is something to sit with rather than rush.
Drag a car with the mouse or a finger. It's comfortable on a phone and works fine on desktop.
