First to Twenty! 🎮

Time for a real game! 🎲 Keep rolling and adding points. The first to reach 20 wins! 🏆

The Game Plan 📋

Our game will: start at 0, roll the dice, add points, and stop when we reach 20!

print('Goal: reach 20 points! 🎯')

Set Up the Score 0️⃣

Start the points at zero.

points = 0
goal = 20
print('Score:', points, 'Goal:', goal)

Keep Rolling With while 🔁

A while loop repeats UNTIL something happens. Keep rolling while points are under 20!

import random
points = 0
while points < 20:
    points += random.randint(1, 6)
print('Reached:', points)

Show Every Roll 👀

Print each roll so we can watch the score climb!

import random
points = 0
while points < 20:
    roll = random.randint(1, 6)
    points += roll
    print('Rolled', roll, '- score', points)

Win Message! 🥳

When the loop ends, you reached 20 — print a winner message!

import random
points = 0
while points < 20:
    points += random.randint(1, 6)
print('You win with', points, 'points! 🥳')

Count the Rolls 🔢

How many rolls did it take? Let's count!

import random
points = 0
rolls = 0
while points < 20:
    points += random.randint(1, 6)
    rolls += 1
print('Won in', rolls, 'rolls! 🎲')

Player One Plays 🧑

Let Player 1 play their turn to reach 20.

import random
p1 = 0
r1 = 0
while p1 < 20:
    p1 += random.randint(1, 6)
    r1 += 1
print('Player 1 took', r1, 'rolls')

Player Two Plays 🧑

Now Player 2 takes their turn!

import random
p2 = 0
r2 = 0
while p2 < 20:
    p2 += random.randint(1, 6)
    r2 += 1
print('Player 2 took', r2, 'rolls')

Find the Winner 🥇

Fewest rolls to reach 20 wins! Compare the two players.

r1 = 5
r2 = 7
if r1 < r2:
    print('Player 1 wins! 🥇')
else:
    print('Player 2 wins! 🥇')

The Whole Game! 🎮

Here's the full two-player game. Run it and see who wins! ✨

import random
def play():
    points = 0
    rolls = 0
    while points < 20:
        points += random.randint(1, 6)
        rolls += 1
    return rolls
p1 = play()
p2 = play()
print('Player 1:', p1, 'rolls')
print('Player 2:', p2, 'rolls')
if p1 < p2:
    print('Player 1 wins! 🏆')
else:
    print('Player 2 wins! 🏆')
