Mahjong is a tile-based table game that originated in China many centuries ago. The goal of the game is for players to create sets of tiles from the walls of tiles which, when completed, can be used to score points. The game is usually played with four people, although it can also be played with just two or three people.
The game is popular around the world, most notably in China and Japan, though it is easy to find versions of it online to play regardless of geographic location. The game is thought to help people develop better problem-solving and strategic thinking skills, as well as fostering cooperation and communication between players.
