# Magic 8 tutorial
Show a string to instruct the user how to play Magic 8! The magic 8 ball can only answer questions with "YES", "NO", or "MAYBE"...
## Rebuild the game!
The blocks have been shuffled! Put them back together so that...
* show "ASK A QUESTION" on the screen
* when the @boardname@ is shaken,
* generate a random number between 0 and 2.
* if the number is `2`, show "YES"
* if the number is `1`, show "NO"
* otherwise show "MAYBE"...
```shuffle
basic.showString("ASK A QUESTION")
input.onGesture(Gesture.Shake, () => {
let randomNumber = Math.randomInt(3)
if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
} else {
basic.showString("MAYBE")
}
})
```
