Probably your concern is what is the most accurate and correct info. As well Im blase on full details but that's human nature you ever play the telephone game ;-)
If you go and use GPT for this query you will see what rules it lists instantly and as a UX professional less steps/clicks/etc is more and usually wins the game. The rules it provided in a few seconds allowed me to quickly tell them and us to start a new game that we were able to finish to completion. Our first we were not trading 2 or 3 or 4 of the same commodity and had to stop.
I'm more highlighting that there isn't a single set of rules for Pit. The instructions have three different ways of playing.
You asked for "the rules" so GPT gave you some rules, fitting your preconceptions.
You asked about 'the Pit' and presumably didn't get from the answer that it's simply "Pit", suggesting again that it's fitting to your preconceptions.
I don't use GPT for several reasons, one being that every time I've seen GPT output on any non-trivial topic where I am competent enough to judge it, it's done a poor job, and the more so when you don't know enough to pose the question correctly.
For another example, at https://news.ycombinator.com/item?id=39483825 I noted how ChatGPT's response used 'Sydney', matching the question posed, while the character's name is actually spelled 'Sidney'.
I don't like systems which re-enforce false preconceptions, no matter how nice the UX.
