Your goal is to make as much money as possible before time runs out. The first thing you'll need to do in each level is build your factory. Build it near the middle of the map, and make sure it's close to lots of building sites (they look like dirt tiles).

To make money, you need to send delivery trucks to construction sites. This will cost a little bit of money, and then you'll get paid when the truck completes the delivery. Check each order to see how much it costs and how much money you'll make when you deliver it. Some will make you way more money than others! Also, try to find orders that are as close to your factory as possible. Click on the order to supply it.

Make money faster by finishing more orders. You can buy new trucks to complete orders faster, or buy a new factory that's closer to the building orders. Buy upgrades between levels to make even more money!
