Your goal is to make enough money selling ice cream to move on to the next city. You will have ten days to reach the required amount of money. You will need to make more money for each city as you pass to higher levels. Each day, you can use your available money to purchase cones, ice cream, and toppings by pushing the yellow buttons in the inventory. The greater quantities you buy, the better the deals. For instance, 1 liter of ice cream costs $1.25, but you can purchase 2.5 liters for $2.50, which is more than twice the amount for only twice the price.
