+
+Learn to create an answering machine on the micro:bit
+
+We will use `show string` to show text on the LED screen. *String* is a common name for *text* in programming languages. The function `show string` scrolls the text column by column at a *150* milliseconds interval. If you want to speed up or down the scrolling, simply change the *150*.

+# game of chance challenges
+
+Coding challenges for the answering machine tutorial. 
+
+## Before we get started
+
+Complete the [game of chance](/lessons/game-of-chance/activity) activity and your code will look like this:
+
+```blocks
+basic.showString("SELECT A BUTTON")
+```
+
+
+### Challenge 1
+
+Now we need to to play the game of chance by responding to the message. We want to respond `YOU WIN` when button `A` is pressed. Add a condition for button `A` and inside it show the string `YOU WIN`.
+
+
+```blocks
+basic.showString("SELECT A BUTTON")
+input.onButtonPressed(Button.A, () => {
+    basic.showString("YOU WIN")
+})
+
+```
+
+* `Run` the code to see if it works as expected.
+
+### Challenge 2
+
+What if micro:bit's answer to the question is GAME OVER? Let's have `GAME OVER` be displayed when button `B` is pressed. Add a condition for button `B` and inside it show the `GAME OVER`.
+
+```blocks
+basic.showString("SELECT A BUTTON")
+input.onButtonPressed(Button.A, () => {
+    basic.showString("YOU WIN")
+})
+input.onButtonPressed(Button.B, () => {
+    game.gameOver()
+})
+```
+
+* `Run` the code to see if it works as expected.
+
+### Challenge 3
+
+When you are asked a yes or no question, do you always say yes or no? Add a condition for `on shake` that displays `TRY AGAIN`.
