Mahjong in Congo is an online casino game that combines elements of board, card and tile-based game-play. The game has been popular in China for centuries and continues to be enjoyed by many people around the world today. Mahjong in Congo is typically played with a set of mini-sized tiles that resemble dominoes. Players must attempt to match pairs of tiles by color and/or design, and then use their tiles to construct "walls" between their opponents. Points are scored by constructing the longest walls and claiming victory in the contest.
