Enjoy Mahjong Shanghai Dynasty, a classic mahjong game in which you eliminate pairs of identical tiles from a shape carefully laid out on the game area. You can only select tiles with at least one free side on their left and/or right. Additionally, pieces with tiles on top of them cannot be chosen. If you feel that the images are difficult to tell apart, you can use the numbers and letters in the top-right corners of the tiles to identify them. This Mahjong game does not have a time limit.
