Have you ever found yourself reminiscing about your first forays into the world of programming? Well, that’s where I found myself recently, recalling a simple card game I programmed in Fortran 77 when I was 14. I used my father’s USSR-made mainframe machine, punching in the code on paper cards. It was my first serious programming endeavor, and it ignited a passion that carried me through a career in software engineering, all the way to the lofty heights of the CTO position.
Over the past decade, though, my role became increasingly focused on management, leaving little room for my first love – coding. So when OpenAI introduced ChatGPT with its ability to write code, my curiosity was piqued. I thought, “Why not put this AI to the test?” And the perfect challenge came to mind: recreating that original card game simulation, but this time, in Python.
The process began with defining the game rules. Surprisingly, ChatGPT grasped the rules almost instantly, needing only minor corrections. With the game definition complete, I moved on to the planning phase. I requested ChatGPT to devise a Python OOP programming plan, outlining necessary classes, properties, methods, and the game flow algorithm. This too, required only a few tweaks before it was ready.
Finally came the actual coding. To my astonishment, ChatGPT’s first attempt was near perfect. This step completed the whole process in just 1.5 hours – a stunning achievement, considering the complexity of the game’s logic.
The experience rekindled a sense of wonder and excitement, much like that young boy coding on the USSR-made mainframe. More importantly, it also showed me the extraordinary potential of AI like ChatGPT in making programming more accessible and enjoyable.
Interestingly, I tried a similar exercise with Bard but the results were far from comparable. It’s clear to me that ChatGPT brings something unique to the table.
Here’s a glimpse of my enlightening conversation with ChatGPT.
“Drunk” Card Game.
User
Cards Game “drunk” description
A card deck that starts with 6 (not with 2) is shuffled and divided into two equal by the number of cards decks which from now on are called deck1 and deck2
Then the game is played in rounds
Each round consists of choosing the upper card from deck1 and deck2, comparing these cards, and putting both of them on the bottom of deck1 if its card is stronger than that from deck2. If the card from deck 2 is stronger than the card from deck 1 both cards go to the bottom of deck 2. A 6 is stronger than an ace. All other cards’ strength is standard as in any card game.
The game ends when either desk1 or desk2 is empty.
ChatGPT
The game you described is called “Drunk” and is a simple card game played with a standard deck of cards, except that the deck starts with 6 instead of 2. Here are the rules of the game:
1. Shuffle the deck and divide it into two equal piles, deck1 and deck2.
2. Each round, players draw the top card from their respective decks and compare them.
3. The card with the higher value wins. If the cards have the same value, the game continues to the next round.
4. The winner takes both cards and places them at the bottom of their deck.
5. A 6 is the highest value card, followed by King, Queen, Jack, 10, 9, 8, 7, 5, 4, 3, and Ace (which is the lowest value card).
6. The game ends when one of the decks is empty, and the player with the most cards remaining in their deck is the winner.
As the name suggests, this game can be played with drinks, where the loser of each round must take a sip of their drink. However, it’s important to drink responsibly and not to overdo it.
User
It is correct except of
1. There are no 5,4, and 3
2. 6 is the weakest card but it beats Ace
3. Ace is the strongest card
Please correct you summary
ChatGPT
I apologize for the mistake in my previous response. Here is the corrected description of the “Drunk” card game:
Objective: To win all the cards from the other player’s deck.
Setup: The deck consists of standard cards from Ace to King, excluding 2, 3, 4, and 5. The game starts with 6 as the lowest value card.
Gameplay:
1. Shuffle the deck and divide it into two equal piles, deck1 and deck2.
2. Each round, players draw the top card from their respective decks and compare them.
3. The card with the higher value wins. If the cards have the same value, the game continues to the next round.
4. The winner takes both cards and places them at the bottom of their deck.
5. The highest value card is Ace, followed by King, Queen, Jack, 10, 9, 8, 7, and 6, which is the lowest value card. However, 6 beats Ace, making it the strongest card in the game.
6. The game ends when one of the decks is empty, and the player with the most cards remaining in their deck is the winner.
Additional Rules: Players can add a drinking element to the game, where the loser of each round takes a sip of their drink. However, it’s important to drink responsibly and not to overdo it.

6. The game ends when one of the decks is empty, and the player with the most cards remaining in their deck is the winner.
User
Please create a plan for writing an OOP Python program for the game. Specify classes with their properties, methods, and a game flow algorithm. The program should print the initial desk1 and desk2 piles, the results of each round, and the desk piles after every 10 rounds. Please don’t write the program itself.
ChatGPT
Sure, here’s a plan for an OOP Python program for the “Drunk” card game:
Classes:
1. Card – represents a single card in the deck.
Properties:
– value (int) – the value of the card (from 6 to Ace).
– suit (string) – the suit of the card (e.g. ‘hearts’, ‘diamonds’, ‘clubs’, or ‘spades’).
2. Deck – represents a deck of cards.
Properties:
– cards (list) – a list of Card objects in the deck.
Methods:
– shuffle() – shuffles the deck randomly.
– draw() – removes and returns the top card from the deck.
– add_card(card) – adds a Card object to the bottom of the deck.
– is_empty() – checks if the deck is empty.
3. Player – represents a player in the game.
Properties:
– name (string) – the name of the player.
– deck (Deck) – the player’s deck of cards.
Methods:
– draw_card() – draws a card from the player’s deck.
– add_cards(cards) – adds a list of cards to the bottom of the player’s deck.
– take_turn(opponent_card) – compares the player’s card with the opponent’s card and returns the result.
4. Game – represents the game.
Properties:
– player1 (Player) – the first player.
– player2 (Player) – the second player.
– round_count (int) – the current round number.
Methods:
– start() – starts the game and runs the game loop.
– print_decks() – prints the current state of the decks.
– game_loop() – runs the main game loop and handles the logic of each round.
– end_game() – ends the game and prints the winner.
Game Flow Algorithm:
1. Create a Deck object and populate it with Card objects from 6 to Ace.
2. Shuffle the deck.
3. Create two Player objects and divide the deck between them.
4. Create a Game object and set the two players as its properties.
5. Call the Game object’s start() method to start the game loop.
6. In the game loop, each player takes turns drawing a card and comparing it to their opponent’s card.
7. The player with the higher card value wins the round and takes both cards, placing them at the bottom of their deck.
8. If the cards have the same value, the game continues to the next round.
9. After every 10 rounds, print the current state of the decks.
10. The game ends when one player’s deck is empty, and the other player is declared the winner.
User
Please add to the above
1. in (3) specify that the division between players is equal – each player gets the same number of cards
2. Add an explanation of printing a round result
3. Elaborate more on the (8) – continue to the next rounds till one side wins and takes all the cards
ChatGPT
Sure, here are the updated instructions for the OOP Python program:
1. Create a Deck object and populate it with Card objects from 6 to Ace.
2. Shuffle the deck.
3. Create two Player objects and divide the deck between them equally (each player gets the same number of cards).
4. Create a Game object and set the two players as its properties.
5. Call the Game object’s start() method to start the game loop.
6. In the game loop, each player takes turns drawing a card and comparing it to their opponent’s card.
7. The player with the higher card value wins the round and takes both cards, placing them at the bottom of their deck.
8. If the cards have the same value, the game continues to the next round until one player wins and takes all the cards.
9. After each round, print the result of the round, including the cards drawn by each player and the winner of the round.
10. After every 10 rounds, print the current state of the decks.
11. The game ends when one player’s deck is empty, and the other player is declared the winner.
Printing a round result:
After each round, print the result of the round, including the cards drawn by each player and the winner of the round. For example, the output might look like this:
“`
Round 1:
Player 1 drew the 7 of hearts
Player 2 drew the Ace of diamonds
Player 2 wins the round
“`
Elaboration on step 8:
If the cards have the same value, the game continues to the next round until one player wins and takes all the cards. The players keep drawing cards and comparing them until one player has a higher card value. When one player wins the round, they take all the cards that were drawn in that round and place them at the bottom of their deck. If a player runs out of cards during a round, the game ends and the other player is declared the winner.

The `game_init()` function initializes the game by creating a deck, splitting it in half, and creating the `Player` objects. In the `main()` function, we repeatedly play rounds of the game until one player runs out of cards, and print the results of each round and the state of the players’ decks every 10 rounds. Finally, we print the name of the winning player.

Please add the following prints and leave the rest of the code untouched
1. Print the piles before the first round. Print all the cards of each player in addition to the number of cards.
