We need a dump truck to carry all those pile of dirt to pile on those UN -leveled platform, so we can build something out of it and make it a useful piece of land. Most of the time, we do this to a land that we want to turn into a residential lot. No platform can sit on top of an UN-levelled land. We need to level it first before we can start the construction. The building of the house would be impossible without it. Honestly, that is the best way to use those pile of dirt. In this game, you are the driver of the dump truck, but this truck is unlike the common truck that you see since it is massive. You need to reach the dumpsite and go to the next level. However, that won't be easy since the terrain is difficult and there are lots of parked vehicles in the area. The game would be harder and more difficult as you make some progress. You can't access the next level if you aren't able to master the current level first. To do that, you just need go the finish line as fast as you can.
