Where can I play it?
Mahjong Time offers numerous tournaments with chips (games for fun), coins (tournament buy-ins), and cash which is the transaction method. It is safe and I have paid for all myself using paypal. I'm unsure about credit transactions though. The cash games are using REAL CASH and you must be 18+ to submit transactions. Under law they are not defined as an online casino as they have argued with district courts in southern California that mahjong is purely based on skill. Their headquarters is based in San Diego, California.
On Facebook's search app bar, there is a decent version called Mahjong Hong Kong. Just type that in and you will be led to a logo with a mahjong tile surrounded by a blue and yellow back round. It is pretty good if you run out of chips on Mahjong Time and serves its purpose. I recommend it for practice as you can take your time on this version.
