But I want to know the basic theory to play within a multiplayer?
In light of what others have said already, I think you need to clarify your question. What do you mean by 'the basic theory to play within a multiplayer'?
Many different versions of classic dice games can be found at casinos, but the basic concept remains the same: players bet on the outcome of a pair of dice. Unlike physical casino, online casinos use a provably fair random number generator instead of dice. It is also possible to play multiplayer versions, in which players compete against each other, but the specific concept of each game will vary.
I do think that the OP does wanna know how will the classic dice game work out when they wanna do multiplayer. I do think that it would be the same the either way and you would just take turns to see who wins and who doesn't at the end of the day.
It's not complicated at all, there are many traditional games as well, I did some online research. Many games with multiple dices and many games with multiple players as well therefore if OP does wanna know about those then here you go :
