## Before we get started

Your beginning code should look like this:

```blocks 
let coll: string[] = []
coll.push("puppy")
coll.push("clock")
coll.push("night")
coll.push("cat")
coll.push("cow")
input.onGesture(Gesture.LogoUp, function () {
    let index = Math.randomRange(0, coll.length)
    let word = coll[index]
    basic.showString(word)
})
input.onGesture(Gesture.ScreenDown, function () {
    game.addScore(1)
})
game.startCountdown(30000)
```

## Challenge 1

Let's add more words for the player to act out! But first, we need to increase the time in one round to give the player more time get through all the words. Let's change the ``||game:start countdown||`` statement.

```blocks
let coll: string[] = []
coll.push("puppy")
coll.push("clock")
coll.push("night")
coll.push("cat")
coll.push("cow")
input.onGesture(Gesture.LogoUp, function () {
    let index = Math.randomRange(0, coll.length)
    let word = coll[index]
    basic.showString(word)
})
input.onGesture(Gesture.ScreenDown, function () {
    game.addScore(1)
})

game.startCountdown(60000) 
```

* Run your code to see if it works as expected

## Challenge 2

Now let's add 5 more words to our list of charade words. Right above the the line ``||arrays:get value at index||`` add 5 lines that say ``||arrays:coll add value to end||``. In this example, we will add the words **bicycle, telephone, sun, car, and ant** but you can add whatever words you like.

```blocks
let coll: string[] = []
coll.push("puppy")
coll.push("clock")
coll.push("night")
coll.push("cat")
coll.push("cow")
coll.push("bicycle") 
coll.push("telephone") 
coll.push("sun") 
coll.push("car") 
coll.push("ant") 
input.onGesture(Gesture.LogoUp, function () {
    let index = Math.randomRange(0, coll.length)
    let word = coll[index]
    basic.showString(word)
})
input.onGesture(Gesture.ScreenDown, function () {
    game.addScore(1)
})
game.startCountdown(30000)
```

* Run your code to see if it works as expected.

## Challenge 3

Remove a life using ``||game.remove life||`` when the screen is down using the ``||input:on screen down||`` event.

## Challenge 4!

Play the game and try guessing all these words in less than 2 minutes!
