Alright kiddo! A "business game" is a make-believe type of game. You pretend to be someone who owns and runs a business, like a store or a restaurant.
Just like in real life, you have to make decisions about how to run your business. For example, you have to decide what things to buy to sell in your store, how to price them, and how to advertise them.
But in this game, you don't use real money! You use pretend money. And the other players are also pretending to run their own businesses.
You get to see how each other's businesses are doing, and you can even compete with each other to see who can make the most pretend money by the end of the game.
It can be a really fun way to learn about how businesses work and what it takes to be successful in real life!
