+### ~avatar avatar
+
+Build a Rock Paper Scissors game with the BBC micro:bit!
+You can play the game with a friend who has it on a micro:bit.
+You can also play it with friends who are just using their hands.
+
+### ~
+
+## Step 1: Getting started
+
+We want the micro:bit to choose rock, paper, or scissors when you
+shake it.  Try creating an ``on shake`` block so when you shake the
+micro:bit, it will run part of a program.
+
+Clear up the blocks and add the blocks below.
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    
+})
+```
+
+Next, when you shake the micro:bit, it should pick a random number from `0` to `2`
+and store it in the variable `item`.
+
+Add a ``set`` block with a variable. Then add a ``pick random`` block,
+and store the random number in the variable,
+like this:
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let item = Math.random(3)
+})
+
+```
+
+### ~hint
+No one can predict random numbers. That's what makes them great for Rock Paper Scissors!
+### ~
+
+Each possible number these blocks can make (`0`, `1`, or `2`) means a different picture.
+We will show the right picture for that number on the LED screen.
+
+
+## Step 2: Picking paper
+
+Put an ``if`` block after the ``let`` block that checks whether
+`item` is `0`. Make sure the ``if`` block has an ``else if`` part
+and an ``else`` part.
+
+Next, add a ``show leds`` block that shows a
+picture of a piece of paper:
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let item = Math.random(3)
+    if (item == 0) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+    } else if (false) {
+
+    } else {
+
+    }
+})
+```
+
+## Step 3: A random rock
+
+Now we are going to add a new picture for the micro:bit to show
+when another random number comes up.
+
+Make the ``else if`` part check if the variable `item` is `1`.
+Then add a ``show leds`` block with a picture of a rock.
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let item = Math.random(3)
+    if (item == 0) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+    } else if (item == 1) {
+        basic.showLeds(`
+            . . . . .
+            . # # # .
+            . # # # .
+            . # # # .
+            . . . . .
+            `)
+    } else {
+
+    }
+})
+```
+
+## Step 4: Suddenly scissors
+
+Add a ``show leds`` block with a picture of scissors to the ``else`` part:
+
+```blocks
+input.onGesture(Gesture.Shake, () => {
+    let item = Math.random(3)
+    if (item == 0) {
+        basic.showLeds(`
+            # # # # #
+            # . . . #
+            # . . . #
+            # . . . #
+            # # # # #
+            `)
+
+    } else if (item == 1) {
+        basic.showLeds(`
+            . . . . .
+            . # # # .
+            . # # # .
+            . # # # .
+            . . . . .
+            `)
+    } else {
+        basic.showLeds(`
+            # # . . #
+            # # . # .
+            . . # . .
+            # # . # .
+            # # . . #
+            `)
+    }
+})
+
+```
+
+### ~hint
+
+You don't need to check if `item` is `2` because `2` is the only number left out of `0`, `1`, and `2`.
+That's why you can use an ``else`` instead of an ``else if``.

+
+Have fun!
+
+## Step 5: Are you the greatest?
+
+Here is a way you can make your Rock Paper Scissors game better.
+When button ``A`` is pressed, 
+the micro:bit will add `1` to your score.
+
+Open the ``Game`` drawer, and then add the block ``change score by 1`` to your program,
+like this:
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1)
+})
+
+```
+
+## Step 6: Prove you're the greatest!
+
+After your micro:bit can add `1` to the score, show how many wins you have.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    game.addScore(1)
+    basic.showString("WINS:")
+    basic.showNumber(game.score())
+})
+```
+## Step 7: Staying honest
+
+Success! Your micro:bit can track wins!
+But what about losses? 
+Use the ``Game`` drawer to subtract `1` from your score when you press button `B`. 
+
+Here are all the blocks you will need:
+
+```shuffle
+input.onButtonPressed(Button.B, () => {
+    game.addScore(-1)
+    basic.showString("LOSSES:")
+    basic.showNumber(game.score())
+})
+```
+Click **Compile** to move your program to the BBC micro:bit!
+
+## Your turn!
+
+How else can you make your game better?
