Getting started

Generate list of valid Nerdle solutions (equations):

$ python3 gen_perms.py > all_perms_file.py

Playing

Enter guesses as suggested by the program into Nerdle.

Enter responses from Nerdle as:

• black - 0
• purple - 1
• green - 2

$ python3 play.py
Enter guess:    58-46=12
Enter response: 10201100
Enter guess:    67*9=603
Enter response: 10101001
Enter guess:    35-6*5=5 - for sure 😉

Finding best initial guess

$ python3 gen_best_guess.py

This takes about 20 minutes to complete.

Spoiler: should return 58-46=12 as the initial guess. This guess is now hard-coded in play.py.
