# magic 8 challenges
Coding challenges for the magic 8 tutorial
## Before we get started
2016-04-13 17:27:45 +02:00
Complete the following [guided tutorial](/lessons/magic-8/activity), and your code should look like this:
2016-03-26 00:47:20 +01:00
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
let randomNumber = Math.random(2)
if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
} else {
basic.showString("I DON'T KNOW")
}
basic.showNumber(8)
})
```

### Challenge 1
2016-03-26 00:47:20 +01:00
Now let's increase the number of responses the magic 8 ball can give. How about 5 responses instead? Let's change the limit of `pick random` to 4.
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
let randomNumber = Math.random(4)
if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
} else {
basic.showString("I DON'T KNOW")
}
basic.showNumber(8)
})
```
2016-05-06 18:28:26 +02:00
### Challenge 2
2016-03-26 00:47:20 +01:00
Now have the magic 8 ball respond "Try again" if **randomNumber** is 3.
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
let randomNumber = Math.random(4)
if (randomNumber == 3) {
basic.showString("TRY AGAIN")
} else if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
} else {
basic.showString("I DON'T KNOW")
}
basic.showNumber(8)
})
```
2016-05-06 18:28:26 +02:00
### Challenge 3
2016-03-26 00:47:20 +01:00
Now what about if **randomNumber** is 4? Let's have the magic 8 ball respond "Definitely!".
```blocks
basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
basic.clearScreen()
let randomNumber = Math.random(4)
if (randomNumber == 4) {
basic.showString("DEFINATELY")
} else if (randomNumber == 3) {
basic.showString("TRY AGAIN")
} else if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
}
else {
basic.showString("I DON'T KNOW")
}
basic.showNumber(8)
})
```
**Challenge 4**
Add 3 more responses so your magic 8 ball has 8 possible responses. Be creative!
