In this game, you need to deliver at least the minimum number of stones. No, this stones aren’t for quarrying since they are use for creating jewelry. These stones are composed of gold, silver, diamond, sapphire and other precious stones that you can think of. They will load the stones on your truck and you are set to go once all the stones are loaded. Try not to let any of them fell on the road while you are on your way to your destination. However, it you do drop any of them, never stop as you can’t pick them anyway. Continue on with the delivery.
