The snowstorm last night was very strong that you can hear the hissing sound all over the city. You can expect so see the city covered in snow in the morning. Unfortunately, most vehicles can't be use because there are too much snow on the driveway. It has to be cleared out first before any vehicle could passed through. It is your job to plow the city because that is the job that you have been paid for. Right now, you got the most important of them all since there will be no one to go to their jobs if you can't do your job.
Drive and flow the snow out of the way. You don't have to flow it completely. Well, at least, you just need to flow some snow that would prevent the vehicles from moving. It is important that you flow enough percent of the snow that is indicated on the upper right portion of the screen to move to the next level. The next level will be harder because the percent of snow that you need to clear rises on each level. There are no time limits in this game, so take as much time to figure out how you can do your job.
