+
+Coding challenges for rock paper scissors. 
+
+## Before we get started
+
+Complete the following [guided activity](/microbit/lessons/rock-paper-scissors/activity) , your code should look like this:
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let img = Math.random(3)
+    if (img == 2) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+
+    } else if (img == 1) {
+        basic.showLeds(`
+            . . . . .
+            . # # # .
+            . # # # .
+            . # # # .
+            . . . . .
+            `)
+    } else {
+        basic.showLeds(`
+            . . . # #
+            # # . # .
+            . . # . .
+            # # . # .
+            . . . # #
+            `)
+    }
+})
+
+```
+
+### Challenge 1
+
+When the A button is pressed, increment the score by 1. You can select Game drawer then add change score by 1.
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let img = Math.random(2)
+    if (img == 2) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+
+    } else if (img == 1) {
+        basic.showLeds(`
+            . . . . .
+            . # # # .
+            . # # # .
+            . # # # .
+            . . . . .
+            `)
+    } else {
+        basic.showLeds(`
+            . . . # #
+            # # . # .
+            . . # . .
+            # # . # .
+            . . . # #
+            `)
+    }
+})
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1)
+})
+
+```
+
+* Click *run* to execute your code in the simulator
+
+### Challenge 2
+
+After incrementing the score, display the total number of wins you have.
+
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let img = Math.random(2)
+    if (img == 2) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+
+    } else if (img == 1) {
+        basic.showLeds(`
+            . . . . .
+            . # # # .
+            . # # # .
+            . # # # .
+            . . . . .
+            `)
+    } else {
+        basic.showLeds(`
+            . . . # #
+            # # . # .
+            . . # . .
+            # # . # .
+            . . . # #
+            `)
+    }
+})
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1)
+    basic.showString("WINS:")
+    basic.showNumber(game.score())
+})
+
+```
+
+* Run and compile the code to see if it works as expected.
+
+### Challenge 3
+
+You have successfully tracked and displayed the number of wins on the micro:bit! However, what about losses? Use the Game drawer to change score by -1 when button `B` is pressed.
+
+* Run and compile the code to see if it works as expected.
