Mahjong
riichi mahjong
One of my big interests is things relating to riichi mahjong (リーチ麻雀): a variant of the Chinese tabletop game “mahjong” invented in Japan. It’s a rather complicated, but fun game where the players take turns picking and discarding tiles (which function similar to cards in a game like poker) in order to build a winning hand.
