Some houses are built easily since the land is high, but some land have are low and that would be a problem one the house is erect. The flood could easily go in the house because it is too low. That is why; it is important that it should be filled with land first to make it higher. before starting the construction of the house.
Go to the site, where your truck could be filled with loads of soil. Drive your truck as fast as you can till you reach the site. Try to be careful so you won't drop any of the soil. You know that you are in trouble if you drop any of your cargo, but this is just a game and there is nothing that you can do about that anymore. Continue on your way and this time, try to be a little more careful than before. When you got to your destination, you need to press the Z/X button simultaneously to unload the soil. The game will be harder as you progress in the game, but that won't be a problem if you are up to the challenge yourself.
Play Dumptruck now and feel what it feels like to drive a truck that big!!!
