+## Let's play Rock Paper Scissors!
+
+### ~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.  (The game is built
+like a coin flipper, but with three choices instead of two.)
+
+### ~
+
+## 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``.
+
+### ~
+
+Your game is ready!
+
+Click **Compile** to move your program to the BBC micro:bit!
+
+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?

 # Set Transmit Power
 
-Sets the transmitter power for ``radio`` communications.    
+Make the ``radio`` signal of the micro:bit stronger or weaker.
-The power can be set to a value between 0 (-30dbm) and 7 (+4dbm).
+It can be as weak as `0` and as strong as `7`.
+
+The scientific name for the strength of the ``radio`` signal is
+**dBm**, or **decibel-milliwatts**. A signal strength of `0`
+can be measured as -30 dBm, and a strength of `7` can be
+measured as +4 dBm.
 
 ## Range
    
-At power level 7, in an open area without significant interference (coming from WiFi networks or other devices operating on the 2.4 GHz range), you can get a **range of over 70m**.   
+If your micro:bit is sending with a strength of `7`, and you are in
- 
+an open area without many other computers around, the micro:bit signal
-Indoors (or with additional interference), range will be significantly reduced.
+can reach as far as 70 meters (about 230 feet).
-
-## Important Security Consideration
-
-The functions in the ``radio`` namespace allow the BBC micro:bit to communicate with other micro:bits.
-
-This API does not contain any form of encryption, authentication or authorization. It's purpose is solely for use as a teaching aid to demonstrate how simple communications operates, and to provide a sandpit through which learning can take place.
-
-For serious applications, BLE should be considered a substantially more secure alternative.
-
-```sig
-radio.setTransmitPower(1)
-```
 
 ### Parameters
 
-* ``power`` -- a [number](/reference/types/number) between ``0`` and ``7``.
+* a [number](/reference/types/number) between ``0`` and ``7`` that
+means how strong the signal is.
 
 ### Example
 
-Sets the transmitter power to full power at 7.
+This program makes the ``radio`` send at full strength.
