Guess the number with math random.
### ~avatar avatar
Welcome! This tutorial will help you create a guess the number game! Let's get started!
### ~
Add an event handler when button `A` is pressed.
```blocks
input.onButtonPressed(Button.A, () => {
})
```
Create a local variable of type number `x` and set it to a random number using `pick random`. `pick random` 9 generates a random number between `0` and `9`.
```blocks
input.onButtonPressed(Button.A, () => {
let x = Math.random(10)
})
```
Show the random number on the screen.
```blocks
input.onButtonPressed(Button.A, () => {
let x = Math.random(10)
basic.showNumber(x)
})
```
