Happy Trucks

Happy Trucks is a fill-in puzzle game. Your job is to fill the trucks with liquid. Do this in all 30 levels. Each level has a different truck, so you need to estimate the amount of liquid that will fit in that truck. You shouldn't overfill the truck, nor should you fill it halfway. If you make a mistake in the rating section, you will have to start over at that level. The game is very fun and you will enjoy playing it.
