# magic 8 challenges Coding challenges for the magic 8 tutorial #docs ## Before we get started Complete the following guided tutorial: * [tutorial](/microbit/lessons/magic-8-ball/tutorial) 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, () => { let x = Math.random(3) if (x == 2) { basic.showString("Yes", 150) } else if (x == 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, () => { let x1 = Math.random(5) // *** if (x1 == 2) { basic.showString("Yes", 150) } else if (x1 == 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 ``x`` is 3. ``` basic.showString("Ask a question", 150) basic.showNumber(8, 150) input.onGesture(Gesture.Shake, () => { let x2 = Math.random(5) if (x2 == 3) { basic.showString("Try again", 150) // *** } else if (x2 == 2) { basic.showString("Yes", 150) } else if (x2 == 1) { basic.showString("No", 150) } else { basic.showString("I don't know", 150) } basic.showNumber(8, 150) }) ``` **Challenge 3** Now what about if ``x`` 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, () => { let x3 = Math.random(5) if (x3 == 4) { basic.showString("Definitely!", 150) // *** } else if (x3 == 3) { basic.showString("Try again", 150) } else if (x3 == 2) { basic.showString("Yes", 150) } else if (x3 == 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!
