Mahjong Strategy for Beginners: Efficiency, Defence and Discards

Principle 1: speed beats size

Over a session, the player who wins the most hands wins the most points, even if each hand is small. A cheap hand that finishes stops three other hands from finishing, takes the deal, and in Riichi collects the riichi sticks and the bonus counters. Aim for the big hand only when the tiles hand it to you or when the minimum forces you to.

Principle 2: count how many tiles improve your hand

Every discard is a choice between two tiles, and the right question is: which one leaves more tiles in the wall that improve my hand? A two-sided wait (4-5 waiting for 3 or 6) has eight tiles that complete it; a middle wait (4-6 waiting for 5) has four; a single tile wait has three at most. Keep the shape with more outs, every time, and break pairs and middle waits before breaking two-sided ones.

Early: throw isolated terminals (1s and 9s) and lone honors you have no use for. They connect to the fewest tiles.
Keep tiles 3 to 7 longest. A 5 connects to more sequences than any other tile.
Two pairs are good; three pairs are a problem unless you are going for all pungs or seven pairs. Break the third.
Do not call (chow or pung) a tile that does not take you a full step closer. Calling fixes your hand and tells the table what you have.

Principle 3: read the discards

The discards in front of each player are the only information you get, and they are a lot. A player who discards a suit early does not want it; a player who has thrown no tiles of a suit for ten turns is collecting it. The tiles a player discards after calling tell you what the called set was not.

Three or more discards of one suit from a player: they are not in that suit. The tiles they have not discarded are the ones to fear.
A player who stops discarding honors and starts discarding middle tiles is ready or one away.
In Riichi, a declared riichi is an announcement. From that point every discard you make is a defensive decision, not an offensive one.
In American play, the exposures on the rack and the card together narrow a hand to one or two possibilities. Learn to read the card from the exposures.

Principle 4: know when to fold

When another player is clearly ready and your hand is three or more tiles from finishing, stop trying to win and start trying not to pay. This is the single habit that separates intermediate players from beginners, and it feels terrible the first ten times. A hand that does not win costs nothing; a hand that deals into a big win costs the evening.

Safe tiles, in order

A tile the ready player has already discarded. In Riichi this is absolutely safe (furiten); in Chinese play it is very nearly so, since few players wait on a tile they threw.
A tile discarded by anyone after the ready player’s last discard that they did not claim or win on.
Honors with two or three already visible. Nobody is waiting on the fourth dragon when three are on the table.
Terminals (1 and 9) and tiles “suji” to a discard: if a player threw a 5, the 2 and 8 of that suit are safer, because a two-sided wait on them would also have won on the 5.
Middle tiles (4, 5, 6) of a suit the ready player has not touched: the most dangerous tiles in the game. Throw them only when you have nothing else.

Principle 5: the deal and the winds matter

The dealer is paid more and pays more. When you are dealer, play fast and cheap; keeping the deal is worth more than a big hand. When the dealer is ready, fold earlier than you would against anyone else. A pung of your seat wind or the round wind is a free fan or yaku; keep a pair of them a little longer than other honors.

Variant notes

Chinese (Hong Kong): the three-fan minimum means you usually need one real pattern. Decide by your fourth discard whether the hand is heading for a half flush, all pungs or a cheap common hand with dragons, and shape every discard to it.
Riichi: declare riichi early with a good wait; waiting for a better hand costs more than it gains. Never discard a tile into a riichi that you cannot justify. Learn suji and the honor-count rule before anything else about defence.
American: the Charleston is the strategy. Decide on two or three candidate hands from the card before the first pass and pass away everything that fits none of them. Keep jokers for the sets that need three or more identical tiles; they are wasted on pairs, where they are not allowed anyway.

Five habits to build this month

Before every discard, name the tile you would throw next. If you cannot, your hand has no plan.
Count your outs for the two tiles you are choosing between.
Glance at all three discard rows before every discard, not just your own.
When someone declares or looks ready, say “fold” to yourself and switch to the safe-tile list.
After each session, remember one hand you dealt into and work out which safer tile you could have thrown instead.

Frequently asked questions

Is mahjong a game of luck or skill?

Both, in roughly the proportion of poker. Any hand can be lost to the tiles; over a session, the player who builds efficient hands and defends well wins consistently.

What should I discard first in mahjong?

Isolated honors you have no pair of, then isolated 1s and 9s, then isolated 2s and 8s. Keep middle tiles and anything connected to another tile in your hand.

When should I fold in mahjong?

When another player is clearly ready and you are three or more tiles from finishing. Switch to throwing only safe tiles: ones that player has already discarded, honors with several visible, and terminals.

Is it better to go for big hands or fast hands?

Fast hands, as a rule. Winning more often also stops the other three from winning. Go for a big hand when the deal gives you most of it or the minimum forces it.
