Mahjong Christmas is a puzzle game where the goal is kind of different from your regular mahjong games. You play by matching 2 tiles with each other to remove them from the board, and you'll continue doing this until all the tiles are gone. By the way, you'll be doing this while listening to some awesome Christmas music, so this might put you into the holiday spirit!
Click on one tile to highlight it, and then click on another tile that matches the first one. If the second tile doesn't match, the second tile will be highlighted instead.
