Welcome! This tutorial will help you create a guess the number game! Let's get started!
### ~
To create a new script, go to the [Create Code](/microbit/create-code) page and tap New Project under **Touch Develop**.
Add an event handler when button `A` is pressed.
```
input.onButtonPressed(Button.A, () => {
2016-03-26 00:47:20 +01:00
})
```
Create a local variable of type number `x` and set it to a random number using `math->random`. `math->random(10)` generates a random number between `0` and `10` **excluded**.
```
input.onButtonPressed(Button.A, () => {
2016-03-26 00:47:20 +01:00
let x = Math.random(10)
})
```
Show the random number on the screen.
```
input.onButtonPressed(Button.A, () => {
2016-03-26 00:47:20 +01:00
let x1 = Math.random(10)
basic.showNumber(x1, 150)
})
```
