Story of the design: Mahjong is a tile-based game with a rich history, originating in China around mid-1800s. Hong Kong-style Mahjong is a fast-paced tile game that's super popular across Asia. Played with four people and 144 tiles, it mixes skill, strategy, and a bit of luck. Players take turns drawing and discarding tiles, trying to build a winning hand made of matching sets. The hand shown here is one of the rarest and most exciting - you might've heard of it - it's called the "Thirteen Orphans," plus two Flowers for a bonus touch.Environmentally friendly ceramic coaster works as a placemat for hot or cold beverages, absorbing the water dripping from cups or glasses to keep your tabletop dry and free from water stains.
