# snowflake fall blocks challenges

Coding challenges for snowflake fall. 

## Before we get started

Complete the [snowflake fall](/microbit/lessons/snowflake-fall/activity) activity and your code will look like this:

```blocks
basic.forever(() => {
    basic.showLeds(`
        . . . . .
        . . # . .
        . # # # .
        . . # . .
        . . . . .
        `)
    basic.showLeds(`
        . . # . .
        . # . # .
        # . . . #
        . # . # .
        . . # . .
        `)
})
```

### Challenge 1

### @video td/videos/snowflake-fall-1

To finalize our snowflake fall, let's add a different snowflake pattern.

```blocks

basic.forever(() => {
    basic.showLeds(`
        . . . . .
        . . # . .
        . # # # .
        . . # . .
        . . . . .
        `)
    basic.showLeds(`
        . . # . .
        . # . # .
        # . . . #
        . # . # .
        . . # . .
        `)
    basic.showLeds(`
        . # . # .
        # # # # #
        . # . # .
        # # # # #
        . # . # .
        `)
})

```


* Run your program and see if it works.
