Python code isn't looping player turns

[Reta]

Hey all, so I was tasked to create a Double Hog game. For the most part, with help from my teacher, my code works 95%. However, as for this game, the game loops until a player in the lobby reaches 100 points, in which point a congratulations message appears. But in my code, as soon as each player finishes a turn, e.g. all 4 players get a turn, instead of looping, the code just ends. Also, I would like help for the congratulations message, when printed, how do I make it in a way that it prints out the first user that reaches 100 points? Any help would be much appreciated :)

    print ("-------------------------MAIN MENU-------------------------")
    print ("1. Play a game \n2. See the Rules \n3. Exit")

                break
