Let's Roll Some Dice! 🎲

Welcome to the Roll the Dice game! 🎲

A dice (or "die") has six sides with numbers 1 to 6. We're going to roll one with code! 🎉

console.log('Rolling the dice! 🎲')
console.log('Numbers 1 to 6! 🔢')

The Six Faces 🎲

A die has six faces:

⚀ one
⚁ two
⚂ three
⚃ four
⚄ five
⚅ six

When we roll, we get one of these! 🎯

console.log('A die has 6 sides ⚀⚁⚂⚃⚄⚅')

Random Again! ✨

To roll, we need a random number. Remember Math.random()? ✨

It gives a number between 0 and 1. Let's use it for dice! 🎲

let r = Math.random()
console.log('Random: ' + r + ' ✨')

Make It 0 to 5 🔢

If we multiply by 6 and round down, we get 0, 1, 2, 3, 4, or 5. 🔢

But dice start at 1, not 0... we'll fix that next! 😄

let n = Math.floor(Math.random() * 6)
console.log('Number 0 to 5: ' + n)

Add 1 for Dice! ➕

Dice go from 1 to 6, not 0 to 5. So we just add 1! ➕

Now we get 1, 2, 3, 4, 5, or 6. A real dice roll! 🎲

let roll = Math.floor(Math.random() * 6) + 1
console.log('You rolled: ' + roll + ' 🎲')

Roll Again and Again 🔁

Every run gives a new roll! 🎲 Sometimes 2, sometimes 6, sometimes 4!

It's a surprise every time. 😲

let roll = Math.floor(Math.random() * 6) + 1
console.log('This roll: ' + roll + ' 🎲')

A Roll Function 🛠️

Let's make a little machine called rollDie. Call it anytime to roll! 🛠️

function rollDie() {
  return Math.floor(Math.random() * 6) + 1
}
console.log('Roll: ' + rollDie() + ' 🎲')

Three Rolls! 🎲🎲🎲

Now we can roll three times super easily! 🎲🎲🎲

Just call our machine three times. 🔂

function rollDie() {
  return Math.floor(Math.random() * 6) + 1
}
console.log('Roll 1: ' + rollDie())
console.log('Roll 2: ' + rollDie())
console.log('Roll 3: ' + rollDie())

Show a Dice Emoji 🎲

Let's make it fun! We can show the dice emoji with the number. 🎲

Roll and celebrate! 🎉

let roll = Math.floor(Math.random() * 6) + 1
console.log('🎲 You rolled a ' + roll + '! 🎉')

Lucky Six? 🍀

Did you roll a six? That's lucky! 🍀

We can check with if and celebrate the big roll! 🎉

let roll = Math.floor(Math.random() * 6) + 1
if (roll === 6) {
  console.log('Lucky six! 🍀🎉')
} else {
  console.log('You rolled ' + roll + ' 🎲')
}

You Can Roll Dice! 🎲

Yay! You learned to roll a die in code! 🎉

Math.random() * 6 gives 0 to 5 🔢
Add + 1 to get 1 to 6 ➕
Wrap it in a function to reuse 🛠️

console.log('You can roll dice! ✅')
console.log('Next: two dice! 🎲🎲')

Quick Check 🧠

Brain time! 🤔

Answer it in the interactive lesson

Great Roll! 🎉

You can roll a die with code now! 🎲

Random number 🔢
Multiply by 6 ✖️
Add 1 ➕

Next: let's roll two dice and add them up! 🎲🎲

console.log('Lesson done! ⭐')
console.log('Two dice next! 🎲🎲')
