Mahjong Solitaire vs American Mahjong: Key Differences
The confusion is understandable. Both games are called "mahjong." Both use the same set of tiles. They show up in similar places online. But they are completely different games, different objectives, different rules, different number of players, different skills.
If you've been enjoying Mahjong Solitaire for years and just discovered there's a "real" mahjong, this is the page that explains the difference and why solitaire players often end up loving the real game.
Mahjong Solitaire: the tile-matching puzzle
Mahjong Solitaire (sometimes called Shanghai, Mahjong Trails, or just Mahjong on apps) is a single-player puzzle game. Tiles are arranged in a layered shape (often a turtle, dragon, or pyramid). Your goal is to remove all tiles by matching pairs of identical "free" tiles, tiles with no other tile blocking them on the left, right, or above.
Mahjong Solitaire was invented in 1981 by computer programmer Brodie Lockard, originally as a Plato system game. It uses the visual look of mahjong tiles but borrows none of the actual mahjong gameplay. There's no strategy beyond pattern recognition. There are no opponents. There's no betting, no scoring system, no skill development beyond getting faster at spotting matches.
American Mahjong: the actual game
American Mahjong is a four-player strategy game where each player tries to assemble a winning hand of 14 tiles that matches one of the patterns on the annual NMJL card. Players draw tiles from a wall, discard tiles they don't want, and call discarded tiles from other players to complete groups (Pungs, Kongs, Quints).
The game includes the Charleston (a unique tile-passing ritual at the start), Joker tiles (wild cards that substitute for any tile in groups of three or more), and a card-driven set of rules that changes annually. There's strategy, defensive play, table awareness, opponent reading. A typical game lasts 10-20 minutes and a session is often four or more games.
Why solitaire players often love real mahjong
If you've enjoyed thousands of hours of Mahjong Solitaire, you already have skills that transfer:
- You recognize tiles fast, the suits, honors, jokers
- You're comfortable with the visual aesthetic and the cultural references
- You enjoy the meditative quality of arranging tiles
What you've been missing is the social element, the competitive depth, and the puzzle of building a hand from a constantly changing pool of tiles. American Mahjong adds all of those without removing what you liked about solitaire.
How to try American Mahjong if you've only played solitaire
The fastest way is to play a few games against bots on americanmahjongg.app. The site is free, no signup, and the tile recognition skills from solitaire mean you'll feel oriented from the first hand.

Most solitaire-to-American-Mahjong converts say their first three to five games are confusing, then something clicks and the game becomes hard to put down.
