American Mahjong Scoring Explained

Scoring in American mahjong is refreshingly simple compared with Chinese and Japanese styles. There are no fan or han tables to memorise and no counting of individual sets. Each winning hand on the card has a fixed value, and a few rules decide how much each player pays. This guide explains every rule, then walks through worked examples so you can settle a hand at the table in seconds.

Where the points come from

Every line on the card ends with a point value. On most cards values range from 25 points for common hands up to 50 or more for the hardest ones, usually concealed hands, singles and pairs, or hands that need several quints. The value is the base amount; who pays and how much depends on how you won.

That value never changes based on which tiles you happened to use. A hand worth 25 is worth 25 whether you completed it with three jokers or none, except for the jokerless bonus described below.

Winning on a discard

If you complete your hand by calling another player's discard:

• The player who discarded pays you double the hand's value.
• The other two players each pay you the value.

For a 25-point hand, the discarder pays 50 and the two others pay 25 each, for a total of 100 points. This is why discarding a tile that gives someone mahjong hurts: you pay twice as much as everyone else.

Winning by self-draw

If you draw the winning tile from the wall yourself (often called self-picked), there is no discarder to blame:

• All three players pay you double the value.

For a 25-point hand that means 50 from each player, a total of 150 points. Self-drawn wins are worth half again as much as discard wins, which is one reason patient players often wait rather than call a risky discard.

The jokerless bonus

If your winning hand contains no jokers at all, its value doubles before payments are worked out. That includes your exposures: if any group you exposed still contains a joker, the hand is not jokerless.

The jokerless bonus does not apply to singles and pairs hands. Jokers can never be used in singles or pairs, so those hands are always jokerless and their higher card value already reflects that.

With the bonus, a 25-point jokerless hand is scored as 50:

• Won on a discard: the discarder pays 100, the others pay 50 each, a total of 200.
• Self-drawn: everyone pays 100, a total of 300.

Worked examples

A quick way to remember it: start from the card value, double it if there are no jokers, then double again for anyone who has to pay double.

Wall games and dead hands

Wall game. If the last tile is drawn and discarded with no winner, the hand is a wall game. No one pays, the tiles are shuffled and the deal passes as usual.

Dead hands. A hand becomes dead when it can no longer match any line on the card, most often because a player exposed groups that no single hand allows, or has the wrong number of tiles. A player with a dead hand stops drawing and discarding for the rest of the hand. Under the standard rules they still pay the winner like everyone else. Many groups have house rules about errors, so agree on them before you start.

Mistaken mahjong. If a player declares mahjong by mistake and exposes their hand, most groups treat that hand as dead. Again, house rules decide whether any penalty is paid.

Keeping score

Groups score in different ways:

• Coins or chips. Many groups play for small stakes, such as a few cents per point, settling with coins or chips after each hand.
• Paper. Write each player's running total; the player with the most points at the end of the session wins.
• Points only. Online and in our trainer, scores are simple numbers with no money involved.

Whatever you use, settle each hand before the next deal so totals stay accurate.

Compared with Hong Kong and Chinese scoring

If you learned mahjong in Hong Kong or China, American scoring will feel very different:

• Hong Kong mahjong counts faan: points for features of your hand such as all one suit, all pungs or sets of dragons. Most tables need a minimum of three faan to win, and a payment table turns faan into points that roughly double with each step.
• Chinese official rules add up a long list of scoring elements and need a minimum of eight points.
• Japanese riichi counts han and fu and has its own detailed tables.
• American mahjong skips all of that. The card already fixed the value when the hand was written, so you only need to know how you won and whether you used jokers.

The trade-off is that the card limits which hands can win at all. In Hong Kong mahjong you can win with almost any complete hand that reaches the minimum; in American mahjong only the lines on the card count, no matter how good your tiles look.

Common scoring questions at the table

Does exposing change the value? No. An exposed hand and a concealed hand are only worth different amounts when the card lists them as different lines. Calling a discard for a pung does not lower your score.

Does a joker swap change the value? No. Swapping a real tile into someone's exposure to take their joker changes nothing about either player's score; it only changes which tiles each player holds.

What if two players want the same discard for mahjong? The player next in turn after the discarder gets it. Mahjong always takes priority over a call for an exposure.

What if I win with the last tile of the wall? It is scored like any other self-draw: everyone pays double.

How scoring should shape your choices

Scoring is simple, but it still affects strategy:

1. Value is not everything. A 25-point hand you can finish beats a 50-point hand you cannot. Choose the line closest to your tiles first.
2. Use jokers freely when it matters. The jokerless bonus is nice, but holding out for it often costs the whole hand. Go jokerless only when it happens naturally.
3. Defence pays. Because the discarder pays double, the cheapest point you can save is the one you do not hand to an opponent. Late in the hand, avoid discarding tiles that match other players' exposures.
4. Self-draws are worth more. If your hand is one tile away and a risky discard appears, consider whether waiting to draw it yourself is better.

Practise with automatic scoring

The Mahjong Coach settles every American practice hand with these rules: card value, double for the discarder or for everyone on a self-draw, and the jokerless bonus except for singles and pairs. The end-of-hand card shows exactly who paid what, so after a few hands the arithmetic becomes automatic. Start with the two Charleston lessons, then move on to full practice hands against computer opponents.
