What are Mah Jongg House Rules?

Most players follow the rules of the National Mah Jongg League. However, some groups like to switch things up a little by introducing a few rules of their own. When playing, make sure that you are fully aware of what is an official rule and what is a made-up 'house rule' (also known as 'table rule').

When playing in tournaments, or playing online, official rules will be followed, so it's definitely worth knowing what's what. When playing with people you don't know be sure to ask if the game will follow official rules, or include house rules. Here are a few examples of popular house rules: Mish or Mush, Atomic, Hot Wall, Cold Wall, Throw and Pick.
