Bagels – A Logic Game in Python

Hey everyone! Today, I’m sharing a fun little Python project: Bagels, a deductive logic game. 🧠

The goal? Guess a secret 3-digit number within 10 attempts.

But instead of getting direct hints, you receive clues to help you figure out the correct number:

Game Rules:

Fermi → A digit is correct and in the right place
Pico → A digit is correct but in the wrong place
Bagels → No correct digits

Example:

If the secret number is “123” and you enter “132”, you’ll see:

Fermi Pico Pico (1 is correct and in the right place, while 3 and 2 are correct but misplaced).

Here’s the full implementation in Python:

Code Breakdown

The program generates a random 3-digit secret number.
The user enters a guess and receives a clue in return.
The game loops for up to 10 attempts or until the player finds the correct number.
At the end, the player can choose to replay or exit the game.

How Can We Improve It?

I have a few ideas, but I’d love to hear your suggestions!

For example:

Add a hard mode where the secret number has no repeated digits.
Create a graphical version using Tkinter or Pygame.
Implement a multiplayer mode, where Player 1 sets a number and Player 2 tries to guess it.

What do you think? Any other improvements you’d suggest?

Let me know in the comments if you tried the game or have any optimizations to propose!
