# truth or dare challenges
A multi-player game that forces each player to reveal a secret or something funny.
## Before we get started
Complete the following [guided tutorial](/microbit/lessons/truth-or-dare/activity), and your code should look like this
```blocks
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
input.onButtonPressed(Button.A, () => {
let random = Math.random(2)
if (random == 0) {
basic.showString("TRUTH")
} else {
basic.showString("DARE")
}
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
})
```
### Challenge 1
Let's make the word "DARE" appear a little more often than "TRUTH". Change the line of code with `pick random (1)` to `pick random (2)`.
```blocks
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
input.onButtonPressed(Button.A, () => {
let random = Math.random(3)
if (random == 0) {
basic.showString("TRUTH")
} else {
basic.showString("DARE")
}
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
})
```
### Challenge 2
Instead of just saying "TRUTH" or "DARE", let's sometimes say "SKIP". This would allow the skipped person to spin the micro:bit without completing a truth or dare. Modify the if statement as shown.
``` blocks
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
input.onButtonPressed(Button.A, () => {
let random = Math.random(2)
if (random == 1) {
basic.showString("TRUTH")
} else if (random == 0) {
basic.showString("DARE")
} else {
basic.showString("SKIP")
}
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
})
```
* Run your code to see if it works as expected
### Challenge 3
Add some other messages, such as "TWO DARES" for the micro:bit to show. You will need to modify the parameter inside `pick random (3)` as well as adding another `if` condition.
