# dice roll challenges
Create a dice on the micro:bit.
## Before we get started
Complete the following [guided tutorial](/lessons/dice-roll/activity), your code should look like this:
```blocks
input.onGesture(Gesture.Shake, () => {
let roll = Math.random(6);
if (roll == 5) {
basic.showLeds(`
. # . # .
. . . . .
. # . # .
. . . . .
. # . # .`);
}
else if (roll == 4) {
basic.showLeds(`
. . . . .
. # . # .
. . # . .
. # . # .
. . . . .`);
}
else if (roll == 3) {
basic.showLeds(`
. . . . .
. # . # .
. . . . .
. # . # .
. . . . .`);
}
else if (roll == 2) {
basic.showLeds(`
# . . . .
. . . . .
. . # . .
. . . . .
. . . . #`);
}
else if (roll == 1) {
basic.showLeds(`
. . . . .
. # . . .
. . . . .
. . . # .
. . . . .`);
}
else {
basic.showLeds(`
. . . . .
. . . . .
. . # . .
. . . . .
. . . . .`);
}
});
```
### Challenge 1
Modify the line of code with `pick random` so that only number 1-4 can appear on the dice.
```blocks
input.onGesture(Gesture.Shake, () => {
let roll = Math.random(4);
if (roll == 5) {
basic.showLeds(`
. # . # .
. . . . .
. # . # .
. . . . .
. # . # .`);
}
else if (roll == 4) {
basic.showLeds(`
. . . . .
. # . # .
. . # . .
. # . # .
. . . . .`);
}
else if (roll == 3) {
basic.showLeds(`
. . . . .
. # . # .
. . . . .
. # . # .
. . . . .`);
}
else if (roll == 2) {
basic.showLeds(`
# . . . .
. . . . .
. . # . .
. . . . .
. . . . #`);
}
else if (roll == 1) {
basic.showLeds(`
. . . . .
. # . . .
. . . . .
. . . # .
. . . . .`);
}
else {
basic.showLeds(`
. . . . .
. . . . .
. . # . .
. . . . .
. . . . .`);
}
});
```
### Challenge 2
Let's make a trick dice! Modify the line of code with `pick random` so that only numbers 3-6 can appear on the dice. Also note that we need to ensure `roll = 0` when only 1 dot is shown on the BBC micro:bit.
```blocks
input.onGesture(Gesture.Shake, () => {
let roll = Math.random(4) + 2;
if (roll == 5) {
basic.showLeds(`
. # . # .
. . . . .
. # . # .
. . . . .
. # . # .`);
}
else if (roll == 4) {
basic.showLeds(`
. . . . .
. # . # .
. . # . .
. # . # .
. . . . .`);
}
else if (roll == 3) {
basic.showLeds(`
. . . . .
. # . # .
. . . . .
. # . # .
. . . . .`);
}
else if (roll == 2) {
basic.showLeds(`
# . . . .
. . . . .
. . # . .
. . . . .
. . . . #`);
}
else if (roll == 1) {
basic.showLeds(`
. . . . .
. # . . .
. . . . .
. . . # .
. . . . .`);
}
else {
basic.showLeds(`
. . . . .
. . . . .
. . # . .
. . . . .
. . . . .`);
}
});
```
### Challenge 3
Add a couple more conditions so that the BBC micro:bit randomly chooses a number between 1 and 8.
