Sudoku command

Description

I would like to make a Sudoku game command for Lancebot. Here are the rules for playing Sudoku, in case you don’t know: https://sudoku.com/how-to-play/sudoku-rules-for-complete-beginners/

Reasoning

Sudoku is one of the most popular puzzle games in the world currently and it provides a good challenge for your brain.

Proposed Implementation

• The bot will print an embed with a 6x6 Sudoku board, like so:
• The grid will have the columns numbered and rows alphabetized, like so:
• User will simply enter their input for the game by typing the coordinates of the square that they want to enter a number in (ex. A3), then the number they want to input (ex. 8). So in this case, what the user would type is: A3 8. If the user guesses correctly, then the bot will automatically update the original embed with the correct guess added. If the user wishes to edit their guess, they may do so by simply editing the message. If the user wants to remove a number from a square, they can type something like this: A3 X.
• Make 2 buttons, one called “Hint” and the other “Give Up”. I think it’s obvious what I want those buttons to do 😃
• To avoid spam of the “Hint” button, I’m going to record the last time the button is pressed using the built-in time module in Python and count 3 minutes from that time and after that time elapses, allow the user to click that button again. Then the process repeats.
• I am also considering the possibility of the bot generating puzzles with multiple or no solutions. The way I’m going to prevent this from happening is by using the backtracking method. I did some research online and I will be using this website as a guide.

Would you like to implement this yourself?

• I’d like to implement this feature myself
• Anyone can implement this feature

Ok, so based off this discussion (starts there), I have (hopefully) made my final decisions as to how I (and others) want this implemented.

• Instead of a 4x4 (or 9x9 for that matter), I will be making a 6x6 grid generator instead
• I will not be adding the embed that says whether a user’s input is right or wrong
• I will also be numbering each column and alphabetizing each row as shown below: That way, I can make it so that user can guess by entering something like B6 8. If the user wishes to edit their guess, they will simply edit the message with their guess. If they wish to remove a number from the board, the user would edit the message to say B6 X.

I believe those are the main takeaways from that conversation I linked. @onerandomusername @Sn4u Let me know if I missed anything.

Lastly, just to make sure: @jb3, do you still approve of this happening with those changes I mentioned above (in this comment)?

What about an image of the board that we edit every time the player makes a move? Could be done with PIL

See https://github.com/python-discord/sir-lancebot/pull/956#issuecomment-997322591

I’m not familar with PIL myself, either
