Real Mahjong Online: 4-Player, Against the Computer, Where to Play

Searching for real Mahjong online usually means one thing: you want the four-player game, with a wall, a dealer, discards and someone across the table, not the tile-matching solitaire that fills most results. This page is honest about where you have landed. 144mahjong.com hosts solitaire, connect and tower boards, which use the same tiles as the table game but are played alone. Below is what the real game actually is, how it differs from those boards, which online services run the four-player game against the computer or against people, and which boards here come closest if what you want is practice with the tiles.

What real Mahjong is

The table game is played by four people with a set of 136 to 144 tiles: three suits (bamboos, characters and circles) numbered 1 to 9, four winds, three dragons and, in most sets, eight flower and season tiles. The tiles are shuffled face down and built into a square wall; each player takes thirteen, and the dealer, seated East, draws a fourteenth. A turn is one draw and one discard. Any discard can be claimed by another player to complete a set of three identical tiles (a pung), four (a kong) or, by the next player only, a run of three (a chow). The hand ends when someone holds four sets and a pair, or when the wall runs out. Then the hand is scored, the deal moves, and the next hand begins; a session is usually sixteen hands, one full rotation of the four winds. The complete beginner’s guide takes the deal step by step, and what is Mahjong explains the tiles themselves.

Four schools account for almost all of the play you will find online. Hong Kong Old Style is the fast Cantonese game with a three-faan minimum; the Chinese Official rules are the tournament standard with 81 scoring patterns; riichi is the Japanese branch with its locked declaration, dora tiles and the furiten rule; American Mah Jongg is the National Mah Jongg League game with jokers, the Charleston and a printed card of legal hands that changes every year. They share the engine and differ in what counts as a hand and what it is worth, which Mahjong hands and scoring sets side by side.

How it differs from the boards on this site

Mahjong solitaire was invented for a computer screen in the 1980s and borrows only the tiles. There is no wall to draw from, no discards, no opponents and no scoring patterns: 144 tiles are stacked in a layout, you remove free pairs, and the board is won when it is empty. Connect boards go one step further from the table, laying the tiles flat and clearing a pair only when a path with at most two turns joins them. Nothing in either format teaches you to read an opponent’s discards or to build a scoring hand, but both teach the tiles by sight, which is the first thing a newcomer to the real game struggles with. Types of Mahjong maps the whole family, and solitaire versus connect compares the two solo formats.

Where to play the four-player game online

The services below run the real game at the time of writing. They are named here as a guide, not as recommendations we are paid for; check each one’s current terms and prices before signing up, because most combine free play with a subscription or in-app purchases.

Riichi (Japanese Mahjong)

Mahjong Soul runs in the browser and as a phone app, with ranked matches against other players, private rooms for friends and practice games against computer opponents; it is free to play and sells cosmetic items. Tenhou is the long-running Japanese server, playable in the browser, free, with a largely Japanese-language interface and a rating ladder that serious players use. Both apply the standard riichi rules explained in the riichi primer.

American mahjong online: Real Mah Jongg and Mahjong 4 Friends

Real Mah Jongg and Mahjong 4 Friends are the two established services for the League game: tables with friends, with community players, with computer players, or a mix, using the current card. Both are subscription products with a free trial period, which is the way to play American mahjong online free on them: try the trial, then decide. The American rules walkthrough covers the turn, the Charleston and the jokers you will meet there.

Hong Kong, Chinese Official and mixed tables

Mahjong Time offers several rule sets on one platform, including Chinese Official, Hong Kong, riichi and American, with play against people or computer opponents; basic play is free and the fuller features are behind a subscription. For the Cantonese game specifically, a number of apps on the phone stores run Hong Kong rules against computer players, and many of them are free with advertising. The Hong Kong rules and scoring guide and the Chinese rules walkthrough will make their settings screens readable.

Against the computer only

If you simply want three opponents who never leave the table, offline games do that better than the networked services. Several riichi and Chinese-rules titles on Steam and the console stores play single-player against three computer opponents, and the Japanese arcade and console tradition of riichi games is decades old. The Mahjong that comes with Windows, however, is solitaire, not the table game, despite the name; the best Mahjong for PC explains which desktop titles are which.

Two and three players

Real Mahjong is built for four seats, but it bends. Japan has sanma, a codified three-player riichi game; Korea and Malaysia have their own three-player traditions; the American League has a procedure for three; and several two-player adaptations exist, including Siamese Mah Jongg. How many people you need lays out the options, with the two-player rules and the three-player rules in detail. Most online services only seat four, filling empty chairs with computer players.

The closest boards here

If your reason for wanting the real game is to learn the tiles, the solo boards on this site are a useful first week. The classic layouts use the full 144-tile set with the traditional faces, so bamboos, characters, circles, winds and dragons become recognisable at a glance; Mahjong Titans is the layout most people already know. Our own Dream Worlds has 78 classic layouts and a Dim blocked tiles setting that makes the free-tile rule visible. For the table game itself, the rules for beginners and the tile symbols cheat sheet are the two pages to print before your first online table.
