Mahjong-H
Mahjong is a tile-based game popularized in East Asia since a very early time. People like it not only for the gameplay of it but also for the physical interaction with mahjong.
Mahjong-H implements a double-side design using the magnetic board. Each side is a board with magnetic powder inside. Just simply swipe the magnetic stick over the bricks to ‘flip’ the sides.
