# guess the number challenges
Coding challenges for the guess the number tutorial.
## Before we get started
Complete the following [guided tutorial](/lessons/guess-the-number/activity), and your code should look like this:
```blocks
input.onButtonPressed(Button.A, () => {
let x = Math.random(9)
basic.showNumber(x)
})
```
### Challenge 1
When button `B` is pressed, we want to clear the screen. This will make it so users can play your game over and over again! Add an event handler to handle this case.
```blocks
input.onButtonPressed(Button.A, () => {
let x = Math.random(9)
basic.showNumber(x)
})
input.onButtonPressed(Button.B, () => {
basic.clearScreen()
})
```
### Challenge 2
Show an animation when you clear the screen! Choose what animation makes most sense to you. Be creative!
