Hey computer scientists.

Welcome to Google CS First Friends.

Today you'll each create a game And you and your friend can play together.

The two of you will work together to catch objects and win points.

I'm going to be great at that.

I hope so, we'll make a great team.

All right.

In the process you'll learn an important computer science concept, variables.

In computer science, variables store information that can change.

So the number of Likes on my Facebook post.

Also stored in a variable.

The display of what song is playing on my music player.

Store it in a variable.

How 'bout the number of lives my video game character has left?

You guessed it, it's stored in a variable.

Wow, variables are everywhere.

Yep, and in today's project you'll use a variable to keep track of the points you and your friend earn together.

Well, let's get started.

Jason will take you through the steps to build your project and I'll see you in the last video.

All right, see you later.

Bye Jason.

Now it's your turn.
