Shanghai, a captivating twist on the classic mahjong solitaire, offers players a fun and engaging experience. The objective of the game is straightforward yet challenging: clear the board by removing all matching pairs of tiles. To successfully remove a pair, each tile must be free on either the left or right side, as well as on top, ensuring they are accessible.

In general, tiles need to match exactly to be removed from the game. However, there are two notable exceptions to this rule that add a layer of strategy to the gameplay. Players have the flexibility to pick any two flower tiles or any two season tiles, regardless of their specific designs, making these tiles key elements in progressing through the game.

With its unique rules and engaging gameplay, Shanghai stands out as a delightful variant of mahjong solitaire, perfect for players looking to test their skills and enjoy a relaxing yet stimulating game.
