Traffic Jam 1.0

the author of this app says:

Move other vehicles out of your way as you try to get your yellow Beetle out of the traffic jam. The fewer moves you make, the higher your score will be. If you can get your car out in a given number of moves (or less), you will go on to the next level. If you have to leave the game and wish to come back to it later, you can do so because this program allows you to save the game and load it again later.

There are 10 levels in the unregistered version, but the full version has hundreds. You will be impressed with the colorful, realistic graphics and sound effects.
