Here is my version of this game I made in early high school a couple years back. So, please forgive the crudeness... https://jondolan.io/fives/

I did not know of this game at the time, but I did hear from people that it was basically Mastermind with words (although I have not played that). The inspiration was a teacher of mine who used to work as a nuclear technician and when he had the graveyard shift, he would play the game with the other technician on duty over the phone.

It's originally called Jotto, and Mastermind is a generalization/de-specification of it that came later.
