TPG writes, "As a change from a usual schedule, I want to start with a little history lesson. According to all the history books ever made, Mahjongg is pretty old. Certainly older than most other games you see on your iPhone, clocking in at around 150 years old depending on which theory you believe. It's no surprise why it's stuck around for so long as it's pretty good fun. There are a few different variants of the game with arguably two being the most popular. One is a four player version a little bit like Rummy or Dominos, while the other is the one that is most often demonstrated in games such as Mahjongg Artifacts 2."
