How to make the game right?

Question

JavaScript

Hello, I'm making a clone of the color switch game. Here is a link to CodeSandbox: https://codesandbox.io/embed/vjk3p48v45
Now I have implemented almost everything, but there is one problem. I can't make the ball go down. That is, I want to make the ball go down at a certain speed and when it reaches the circle, compare the color of the sector and the color of the ball. PS do not judge strictly the code, write such applications for the first time.

So?
