Balance the goods loaded on your truck while driving to the market in this uphill racing game. Your goods are mostly tasty hamburgers, so try not to drop them along the way. The more you deliver whole, the higher your score. When you reach the end of the level, unload your precious cargo at the conveyor belt, then park in the yellow space.
