Welcome! You found a CS First Starter Project for the Sports theme. Watch this video at CS First to learn how to build it: https://csfirst.withgoogle.com/c/cs-first/en/sports/net-sports/introduction-to-conditionals.html If you're a teacher: Lesson plans are also available on the CS First site. If you decide to sign up for a CS First account, you'll be able to track your students' progress, order physical materials (kits), and access your students' projects in Scratch. This is a two player game, where you have to hit the ball, and when you miss the ball, the opponent gets the point. If you know tennis, then this is an online version of the game. If you don't, well then, it's a game that you have to hit the ball at the other person, and get a point if they miss it. I know there are other ways to get points, but they don't exist in this game.
