I have long loved Mahjong. This simple game of tiles which dates back to the Qing dynasty in China has spread rampantly throughout the world since the 20th century. There are dozens of iterations of the game that you can pay for, but why not play this classic for free? Enter Mahjong Shanghai. Mahjong Shanghai, which is found on www.bubbleshooter.net, is free to play, easy to learn, and will soon steal time from you as the addiction grows. Mahjong's concept is to take the tiles as arranged on the board, match them, and clear them. The caveat to this is that only tiles that are free on at least three sides can cleared. Tiles that are blocked, tiles that are covered, and tiles that are stacked cannot be cleared and thus enters the strategy portion of Mahjong. You will have multiple options to clear tiles from the board while trying not to block yourself from tiles you will need to clear to solve the puzzle. What looks easy at first, or at least the next right move may be the one that blocks you from clearing the puzzle. You always have to be a few moves ahead if you want to be successful, and with the growing challenge of the puzzle's design, you will have to adapt your strategy to become a master. Mahjong Shanghai has a simple interface, a nice background, and wonderfully colored tiles that any lover of this true classic will enjoy. Best of all it's free to play.
