Real Tabletop Mahjong vs Solitaire Puzzle
Many online games labeled "Mahjong" are actually single-player Solitaire tile-matching games. Mahjong by Bossrod is the genuine 4-player social strategy game. You draw and discard from a 144-tile wall, call Chow (sequences), Pong (triplets), and Kong (quads), and race to build a winning hand.
