At the end of the tutorial, click keep editing. Your code should look like this:

basic.showString("Ask a question", 150)
basic.showNumber(8, 150)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
    let randomNumber = Math.random(3)
    if (randomNumber == 2) {
        basic.showString("Yes", 150)
    } else if (randomNumber == 1) {
        basic.showString("No", 150)
    }
    else {
        basic.showString("I don't know", 150)
    }
    basic.showNumber(8, 150)
})

Challenge 1

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 math->random to 5.

basic.showString("Ask a question", 150)
basic.showNumber(8, 150)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
    let randomNumber1 = Math.random(5) // ***
    if (randomNumber1 == 2) {
        basic.showString("Yes", 150)
    } else if (randomNumber1 == 1) {
        basic.showString("No", 150)
    }
    else {
        basic.showString("I don't know", 150)
    }
    basic.showNumber(8, 150)
})

Challenge 2

Now have the magic 8 ball respond "Try again" if randomNumber is 3.

basic.showString("Ask a question", 150)
basic.showNumber(8, 150)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
    let randomNumber2 = Math.random(5)
    if (randomNumber2 == 3) {
        basic.showString("Try again", 150) // ***
    } else if (randomNumber2 == 2) {
        basic.showString("Yes", 150)
    }
    else if (randomNumber2 == 1) {
        basic.showString("No", 150)
    }
    else {
        basic.showString("I don't know", 150)
    }
    basic.showNumber(8, 150)
})

Challenge 3

Now what about if randomNumber is 4? Let's have the magic 8 ball respond "Definitely!".

basic.showString("Ask a question", 150)
basic.showNumber(8, 150)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
    let randomNumber3 = Math.random(5)
    if (randomNumber3 == 4) {
        basic.showString("Definitely!", 150) // ***
    } else if (randomNumber3 == 3) {
        basic.showString("Try again", 150)
    }
    else if (randomNumber3 == 2) {
        basic.showString("Yes", 150)
    }
    else if (randomNumber3 == 1) {
        basic.showString("No", 150)
    }
    else {
        basic.showString("I don't know", 150)
    }
    basic.showNumber(8, 150)
})

Challenge 4

Add 3 more responses so your magic 8 ball has 8 possible responses. Be creative!
