Types of Mahjong Games: Every Style Explained

One Name, Many Games

Mahjong is not one game. The moment it left a single province it started splitting, and a century later "mahjong" names at least half a dozen games that disagree about how many tiles you hold, what you are allowed to claim, and what counts as a win. They all share the same 144-tile ancestor and the same draw-and-discard rhythm, which is why they feel related. Everything underneath that rhythm is negotiable, and every region negotiated differently. See also American vs Chinese Mahjong: Key Differences Explained.

This is the map. Each style below gets the same treatment: how many tiles, what scoring looks like, what makes it distinctive, and who it suits. Read the whole thing once, then pick one and stay with it for a while — the fastest way to stay confused is to learn three rulesets in one week and keep mixing their scoring rules together at the table. See also What Is Mahjong? A Complete Beginner Guide.

One thing worth settling first, because it trips up almost every beginner: the same hand shape can be worth very different amounts depending on which style you sit down to. A tidy all-simples hand is a cheap win in one ruleset and a strong one in another. So the question "is this a good hand?" has no answer until you name the game.

Hong Kong Mahjong

The most widely played style outside Japan, and the one we recommend learning first. You hold thirteen tiles, build four sets and a pair, and the only real gate on winning is a three-faan minimum — low enough that beginners score regularly instead of grinding through hand after hand with nothing to show for it.

Scoring is deliberately shallow. A small catalogue of patterns, no yaku list to memorise, no requirement that your hand be concealed. You can call tiles freely and still win; calling simply costs you some faan rather than disqualifying the hand outright.

What makes it distinctive is the pace. Games finish quickly, the minimum keeps hands honest without making them rare, and the scoring is forgiving enough that new players get a win in their first session. Flowers and seasons are usually included as bonus tiles worth a faan each.

Who it suits: anyone who wants a complete game they can be competent at within an evening, and anyone who will later move sideways into Riichi or Chinese Official.

Japanese Riichi Mahjong

The competitive standard, and by some distance the most studied. Riichi adds a declaration you can make once your hand is one tile from completion: you push a thousand-point stake into the table, announce it, and play your remaining draws face up. It converts a quiet endgame into public information and public pressure, which is why the game produces so many memorable finishes.

The gate on winning is yaku, not points. Your hand must contain at least one recognised pattern before it is allowed to win at all, and that single rule changes how the whole game is played — you cannot simply assemble four sets and a pair. Furiten forbids winning on a tile you have already discarded, which makes every discard a lasting commitment.

Red fives, or dora, add a layer of luck players either love or resent. Dora is only revealed after a win and inflates the score of whatever hand happened to contain it, which means a mediocre hand can pay unexpectedly well. A hand of unremarkable shape holding three red fives can outscore a beautifully constructed concealed hand, and experienced players build their risk tolerance around that possibility rather than pretending it away.

Defence is a first-class skill here in a way it is not in the faster styles. Because a single discard into a large hand can cost you more than you have won all evening, reading the table matters as much as reading your own tiles, and the discipline of folding a promising hand is often the correct play. That trade-off between pushing and folding is what gives Riichi its reputation for depth.

Who it suits: players who want a deep, well-documented game with a real competitive ladder and an enormous body of theory to read.

Chinese Official (MCR)

The tournament ruleset, codified so that a player from any country can sit down at an international table and lose to a specialist on equal terms. Eighty-one patterns, an eight-point minimum, and a scoring system built to be unambiguous rather than exciting.

MCR is the most demanding of the styles here in pure breadth. Reaching eight points is easy with the large patterns and nearly impossible with small ones, so real play becomes a hunt for one of the handful of shapes that will clear the threshold. Many points are also awarded for a fully concealed hand or for winning on the last tile, which rewards patience over speed.

The eight-point gate is the defining feature. It is far higher, in practice, than Hong Kong’s three faan, and it means a beginner’s "obvious" hand frequently cannot win at all. That is intentional: the ruleset exists to rank strong players, not to welcome weak ones. The practical consequence is that the first hour at an MCR table is mostly spent counting points rather than playing, and players who arrive from a casual style often lose several hands before they understand why.

Because the catalogue is fixed and published, MCR is unusually fair as a competitive format — everyone has the same eighty-one patterns available, and disagreements get decided by the rulebook rather than by house convention. That standardisation is exactly why international tournaments adopted it.

Who it suits: players interested in competition and standardisation, and anyone who enjoys the puzzle of a large pattern catalogue. Not a first ruleset.

American Mahjong

A genuinely different game wearing the same clothes. It uses 152 tiles — the standard set plus eight jokers — and you do not decide for yourself what you are building. Each year the National Mahjong League publishes a card listing the legal hands, and everyone at the table plays from that card.

Winning therefore means matching a printed pattern rather than constructing a shape, and the skill shifts from hand-reading to card-reading: recognising which of the listed hands your fifteen tiles are closest to, and how far you can drift toward one before committing. Jokers stand in for tiles in most positions, which makes some hands dramatically easier than others for reasons that have nothing to do with your play.

The Charleston opens every hand: three compulsory passes of three tiles, then an optional courtesy pass, which is by far the most social phase of any mahjong game. The card is republished annually, so an expert in one year’s card is a competent beginner in the next — a rare feature in a game this deep.

Who it suits: clubs and social players, especially anyone who wants a fresh puzzle every year rather than a fixed ruleset to master.

Taiwanese Mahjong

Sixteen tiles instead of thirteen, which changes everything downstream. Holding one extra tile per hand means you build five sets and a pair rather than four, and it makes your hand roughly a full step further from completion on average — games last longer, and a single well-timed call matters more.

The distinguishing mechanic is the flower replacement. Whenever you draw a flower or season you place it aside and draw a replacement from the back of the wall, so your hand keeps cycling and the wall drains faster than the tile count suggests. Scoring is by tài, a flexible bonus counter that stacks on top of the base hand value.

Taiwanese play also tends to allow more speculative bidding than Hong Kong, and the extra tile gives you more room to keep a marginal shape alive. If you already know Hong Kong, expect your instincts about hand length to be off by about one tile for your first few games — the extra tile is exactly the trap.

Who it suits: players who know Hong Kong or Chinese Official and want a variant that is genuinely different rather than a scoring tweak.

Sichuan Mahjong

The fast, aggressive blood-battle variant that has become hugely popular for mobile play. There are no honours at all — no winds, no dragons — leaving a 108-tile set. Before play you must void a suit, declaring that you will never win with it, which instantly converts the dense suit-by-suit decisions of other styles into one early commitment.

The "bloody battle" part is the win condition: play does not stop when someone wins. The winner leaves the table, the remaining players continue, and the hand goes on until three of the four have finished or the wall runs out. One deal produces multiple winners, and the player who wins first does not necessarily win the most.

Sichuan scoring is impatient in exactly the way the rest of the ruleset is. It rewards going out fast and punishes the player left holding tiles, and the voided-suit rule makes a bad early decision expensive. It has no concept at all of the thoughtful endgames you see in Riichi, and almost no defensive play — the game is designed so that the cost of stalling is higher than the cost of a bad discard.

The stripped-down tile set is worth understanding separately. Remove the honours and you are left with three suits of thirty-six tiles, which means every tile you need is roughly a third more likely to appear than it would be in a full set. Hands come together fast, the wall is proportionally shorter, and the whole game compresses into a much tighter window.

Who it suits: players who want short, high-tempo games and are happy with a ruleset built for volume rather than depth.

Mahjong Solitaire

Not mahjong, despite the name. It is a single-player tile-matching puzzle in which you clear a stacked layout by pairing off identical tiles that have at least one long side free. There are no opponents, no draws, no scoring decisions — just a layout that is either solvable from where you are or is not, and the only real skill is recognising which pairs you can afford to spend.

It shares the tile faces and the word "mahjong" and essentially nothing else. It is the reason a lot of Western players first type the word into a search box, and it is a legitimately good puzzle you can play free in your browser as Mahjong Solitaire. It is not a way to learn the four-player game, and the two should not be confused when you are choosing something to play tonight.

If the four-player game is what you are after, the styles above are your options and Hong Kong is the gentlest door in. If you want a quiet fifteen minutes with a familiar-looking board, this one is genuinely worth the time — just know which of the two you signed up for.

Who it suits: solo players, and anyone who wants the pleasure of the tiles without the table.

Mahjong Connect

A second single-player take on the tiles, and a different puzzle from solitaire. Instead of clearing a stacked layout, you connect two identical tiles with a path that bends no more than twice, removing pairs until the board is empty. Like solitaire it needs no opponents and no ruleset — just pattern recognition and a little planning.

The two single-player games suit different moods. Solitaire is a slow, layered clear; Connect is a faster, spatial match where the shrinking board pushes you to spot pairs quickly. Both are free to play in the browser and need nothing downloaded, which makes them the easiest way to enjoy the tiles when you do not have time or players for a full four-player game.

If you want the layered puzzle, play Mahjong Solitaire. If you prefer the faster connect-and-clear loop, Mahjong Connect is the one to open. Neither teaches the four-player game, but both are a genuine few minutes of the tiles on any device.
