If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Park your car without caring about any kind of rules or regulations. Use your arrow keys to drive and your space bar to brake and make sure you succeed parking it in time. Do not hit the legally parked cars or the ones in traffic, because you may damage your own car. Try to complete all eight levels successfully and have a lot of fun parking like a boss!
