Mahjong is a tile-based game that originated in China and has a rich history of over 500 years. It's a game of skill, strategy, and luck, and its rules can vary slightly depending on the platform. At Taiwanese mobile casinos, players aim to make the best possible hand from the 13 tiles they are dealt. All Mahjong games must contain four players, so when playing single-player Mahjong, the three remaining players are typically computer-simulated.
Players must create sets of three and four tiles in order to create a winning hand. Additionally, players can opt to call for a discard, which allows them to take a tile from the discard pile that is either matching what they have in their hand or would complete the hand. The game is won when one of the players has formed a winning hand with all of the tiles in their hand.
