Chapter 7. Games of Fortune

In Chapter 6, we learned how easy it is to create projects that incorporate dynamic information using variables. However, variables have a limitation; they store only one value at a time. Sometimes, we want a variable to store multiple values.

Welcome to lists. In Scratch, a list allows us to associate one list (a variable) with multiple items or values in much the same way we create a list before going to the grocery store.

In this chapter, we will take a trip to the fortune-teller to demonstrate lists, and I predict you'll learn how to:

• Store and retrieve information in lists

• Keep track of items in a list by using a counter

• Identify intervals using the mod block

• Use if/else control blocks to make decisions

• Ask the user a question and store the keyboard input

That's a lot to process, but we can do it.
