I think it would be at least forty years ago when I first learnt to play Mah Jong. My brother-in-law and my sister taught us. We enjoyed many fun games with my sister and her husband and we bought a Mah Jong set to use with our children but the set has been in the cupboard for many years now. It is a long while since it has seen the light of day,
I was invited to join a Mah Jong group a couple of weeks ago and have since enjoyed getting back into the flow of the game.
I will admit that I had to read the introductory rules of the game to brush up on the rules before I headed out to my first game. When I joined the group I found that they had a book that was far more detailed than the one I had.
I am really enjoying getting back into the game and I have bought the new book so I can be well prepared for our next get together.
You can see how well-thumbed the book is that one of the player uses.

I’m interested to see that because I was given a Mah Jong set recently. I’ve never played it and the rules look quite complicated to me.
The rules seem complicated but once you start playing it all seems very logical.
