Hong Kong Mahjong Strategy for Beginners

1. Sort your hand into jobs

Before choosing a discard, identify completed sets, a possible pair, incomplete sets and isolated tiles. A normal win needs four sets and one pair, so count the groups you can actually keep together.

Do not count overlapping tiles twice. In 3-4-5-6 Characters, 3-4-5 and 4-5-6 are two ways to use the same tiles, not two completed sets. Keep alternative shapes in mind before breaking one apart.

2. Two-sided, closed or edge wait: count the useful copies

A 4-5 Bamboo group can form a Chow with 3 or 6 Bamboo. A 4-6 group needs 5; a 1-2 group needs 3. Looking only at that group, the first shape accepts two tile types rather than one.

Each type has four copies. Subtract copies in your own hand and publicly visible discards or exposed sets. If all four 3 Bamboo are visible, 4-5 has only the 6 Bamboo route left. Unseen tiles may be in other hands; this count is not a promise that you can draw them.

This compares one incomplete set. The rest of the hand, the pair, faan and risk may change the best discard.

3. Plan how the hand reaches 3 faan

In our house rules, Concealed Hand (1) + All Chows (1) + Self-draw (1) reaches 3 faan. The same shape won on a discard has only 2, unless another scoring item applies. Your plan therefore needs to distinguish self-draw from a discard win.

Half Flush is worth 3 faan here, but it requires one numbered suit together with honours. It is a possible route when your tiles already support it; discarding several useful sets just to force it may slow the hand. Check actual tiles in the calculator before assuming patterns combine.

All faan totals in this guide use our browser house rules, without flowers or other bonuses unless stated. Check the table’s actual scoring before transferring a plan to a real game; a 0-faan training win does not prove the same hand may win at a 3-faan table.

4. Before a Chow or Pung, check three things

Does the claim complete a useful set? Does the hand still have a pair and a route to the winning minimum? Which tile will you discard immediately afterwards? Answer all three before accepting.

For example, claiming a Chow in a hand aiming for Concealed Hand + All Chows removes the concealed bonus. With no other scoring items, All Chows plus Self-draw would now give only 2 faan. Finishing a set faster does not help if the final hand cannot legally win. Passing keeps the concealed route but does not guarantee a better draw.

5. Read visible information without guessing certainty

Look at all three opponents’ exposed sets and discards. Several exposed sets mean fewer concealed sets remain to be formed, but do not prove that the player is waiting or has enough faan. A visible focus on one suit is a reason to reassess that suit, not proof of the whole hand.

A tile that was discarded earlier can still be dangerous now. Our rules do not make a tile permanently safe because someone previously discarded or passed it. When your own hand is far from a legal win, avoid treating every extra scoring chance as a reason to accept more risk.

6. A short decision exercise

Here are 13 tiles: three complete Chows, a pair of 8 Bamboo and 4–5 Bamboo. Assume all groups are concealed and no flowers or other bonuses apply. Either 3 or 6 Bamboo completes the shape. Under our rules, that is 2 faan on a discard or 3 on self-draw, so only self-draw meets the standard minimum.

One 3 Bamboo is already in your hand. If the other three 3s and one 6 are public, with no current discard available to claim, the unseen supply is (4 − 1 − 3) + (4 − 0 − 1) = 3 copies, all 6 Bamboo. Some may be in opponents’ hands; they are not three guaranteed draws.

Decision: recognising a two-sided shape is only the first step. Check the remaining copies, then whether the intended winning method reaches 3 faan. A 6 Bamboo discarded now would complete the shape but would still fail this hand’s standard-table minimum.

Assumptions: concealed hand, no flower or event bonuses, 3-faan minimum. A different table or bonus changes the decision.

7. Practise one decision at a time

First use the lessons to recognise pairs, sets and waits. Then play a guided hand and explain your intended discard before reading the hint. Compare the reasons, rather than simply copying the suggested tile.

Once turns feel comfortable, play a standard 3-faan hand. After settlement, check which patterns counted and whether a claim changed your original plan. Use the four-round match when you want to practise continuing through dealer changes and cumulative scores.
