+
+Welcome! This tutorial will help you create a guess the number game! Let's get started!
+
+### ~
+
+To create a new script, go to the [Create Code](/microbit/create-code) page and tap New Project under **Touch Develop**.
+
+Add an event handler when button `A` is pressed.
+
+```
+input.onButtonPressed("A", () => {
+})
+```
+
+Create a local variable of type number `x` and set it to a random number using `math->random`. `math->random(10)` generates a random number between `0` and `10` **excluded**.
+
+```
+input.onButtonPressed("A", () => {
+    let x = Math.random(10)
+})
+```
+
+Show the random number on the screen.
+
+```
+input.onButtonPressed("A", () => {
+    let x1 = Math.random(10)
+    basic.showNumber(x1, 150)
+})
+```
