Your First Mahjong Game, Turn by Turn

Before the first tile

Rules are easier to absorb in order than as a list. This is one hand, played from the wall to the final payment, with the decision at each step spelled out. It uses Chinese Official rules because that set is the strictest: if you can follow a hand here, every other style is a relaxation of it.

Four players. Dealer sits east; you sit west with 13 tiles. The wall is 136 tiles, no flowers. Base stake agreed at the table before the deal.

Step 1: build the wall

Every player stacks 17 pairs of tiles face down into a square. The dealer throws two dice; the total decides which wall to break and how many stacks in. Tiles are dealt in four rounds of three to each player, then one final tile each; the dealer takes the fourteenth and plays first.

Nothing in this step involves strategy. What matters is that the wall is a fixed resource: every tile you draw comes from it, and every tile your opponents draw comes from the same place.

Step 2: read the deal

Your starting hand:

2 3 3 characters · 5 6 7 circles · 8 8 9 bamboo · east east · white white

Before discarding anything, count what you have:

Two pairs — east and white, either of which can become a set or stay as the pair.
One near-run — 2 3 characters, one tile from a run.
One complete run — 5 6 7 circles.
One awkward pair — 8 8 bamboo with a 9 beside it, which is close to a run but not close enough.

That is a good start: one completed set, three blocks that can become sets, and two pairs to work with.

Step 3: the first three discards

The player to your left discards a 4 characters. You could chow it with your 2-3, but you decline. The 2-3 block waits on two different tiles and can still widen; claiming it locks one set early and spends your chow on the least valuable option.

The player opposite discards a white dragon. You claim it. Three white dragons is a completed set worth fan, and it removes a pair that was competing with your east pair for the pair slot. Your hand drops to 10 tiles plus the meld.

The player to your right discards a 9 bamboo. You decline again. It connects with nothing: your 8-8 pair wants a third 8, and a lone 9 gives you no new block.

Three decisions, one claim. The pattern is: claim when it adds value, decline when it narrows your shape.

Step 4: the middle game

You draw a 1 characters and the 2-3 becomes a complete 1-2-3 run. The hand now reads:

1-2-3 characters (complete)
5-6-7 circles (complete)
White dragon pung (complete, claimed)
8-8-9 bamboo and a pair of east winds

Two sets plus the meld, one near-run, and a pair. You are one set and one pair away from a win, with a clean route: the 8-9 bamboo needs a 7, and the east pair can become the pair or become a pung if a third east appears.

This is the point where most beginners start discarding whatever is not working. Resist that. The 8-8-9 is a real block; every other tile in hand is part of a set.

Step 5: reaching a wait

You draw a third east. Now the hand is complete in shape:

1-2-3 characters
5-6-7 circles
White dragon pung
East wind pung
8-8 bamboo as the pair

Before that draw the hand held two pairs — east and 8 bamboo — a double-pung wait on four out tiles. The third east resolved it into four sets and a pair. And then you check the value.

Step 6: the check that saves you

Count the fan. No honours? No — you have two honour pungs. All pungs? No, you have two runs. Half flush? No, three suits. Terminal pung? The 1 in 1-2-3 is a run tile, not a pung.

The hand scores 4 fan — below the Chinese Official minimum of 8. Declaring it would be a false win, which carries a penalty in tournament play.

This is the lesson the whole walkthrough exists to teach: a hand can be complete, have a wide wait, and still be illegal. Shape and value are two separate checks, and the second one comes first.

Step 7: adjusting instead of declaring

With the hand at 4 fan, you have two choices: keep building toward a pattern that adds value, or continue as though you were waiting and hope to score. The correct move is to keep building — and to stop discarding dangerous tiles while you do it.

The river shows two 7 bamboo and one 9 bamboo already discarded. The 9 is therefore the safer of the two to discard, which means the hand becomes a single wait on 7. Narrower, but the 9 does not come back to hurt you.

That trade — a narrower wait for a safer discard — is the whole of defensive play in one decision.

Step 8: the payment

The player opposite discards the 7 bamboo you were waiting on. You win on a discard, so that player pays the full value alone. The other two pay nothing.

Had you won on a self-drawn tile instead, all three would have paid. That difference is why self-draw is worth chasing when the hand is close: not more points per player, but three payers instead of one.

Step 9: what to review

Three questions after every hand, win or lose:

How many out tiles did I have? If you cannot answer, you were guessing.
How dangerous was my last discard? Name the level, not the feeling.
Could I legally declare? Check the fan before the wait, every time.

Answer those three and the next hand is easier than this one.

Quick answers

Should I claim the first chow offered?

Usually not, if the block you would claim is your widest one. Claim the set that completes value, not the set that is easiest to finish.

Why did a complete hand get rejected?

Because it scored below the style's minimum. In Chinese Official that is 8 fan; in riichi the hand needs at least one yaku.

Is it worth narrowing a wait for a safer discard?

Yes, when an opponent is close to winning. The cost of dealing in is usually larger than the cost of a narrower wait.

Why do self-drawn wins feel bigger?

Because every opponent pays instead of just the discarder. The value per player can be lower and the total still higher.
