+
+Welcome! This tutorial will help you create a guess the number game! Let's get started!
+
+### ~
+
+Add an event handler when button `A` is pressed.
+
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+})
+
+```
+
+Create a local variable of type number `x` and set it to a random number using `pick random`. `pick random` 9 generates a random number between `0` and `09`.
+
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(9)
+})
+
+```
+
+Show the random number on the screen.
+
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(9)
+    basic.showNumber(x)
+})
+

+# guess the number challenges
+
+Coding challenges for the guess the number tutorial. 
+
+## Before we get started
+
+Complete the following [guided tutorial](/microbit/lessons/guess-the-number/activity), and your code should look like this:
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(9)
+    basic.showNumber(x)
+})
+```
+
+### Challenge 1
+
+### @video td/videos/guess-the-number-2
+
+When button `B` is pressed, we want to clear the screen. This will make it so users can play your game over and over again! Add an event handler to handle this case.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    let x = Math.random(9)
+    basic.showNumber(x)
+})
+input.onButtonPressed(Button.B, () => {
+    basic.clearScreen()
+})
+```
+
+### Challenge 2
+
+Show an animation when you clear the screen! Choose what animation makes most sense to you. Be creative!
