In Hong Kong Mahjong, how you win matters almost as much as what you win with. A self-drawn win and a discard win with the same hand can result in very different payouts. Understanding this difference is crucial for both strategy and settling up at the end of the game.

The Two Ways to Win

Discard Win (食糊 / Sik Wu)

You complete your hand by claiming another player’s discarded tile. The player who discarded the winning tile is called the shooter (出銃 / cheut chung).

Self-Drawn Win (自摸 / Zi Mo)

You complete your hand by drawing the winning tile yourself from the wall. No other player “shot” you the tile.

The Key Payment Difference

This is the most important thing to understand:

Win Type	Who Pays
Discard Win	Only the shooter pays
Self-Drawn Win	All three other players pay

With a discard win, the unlucky player who discarded your winning tile bears the entire cost alone. With a self-drawn win, the pain is spread across all three opponents.

But there’s more: a self-drawn win is also worth 1 extra faan (自摸 bonus), which increases the base payout amount.

How Payouts Are Calculated

Let’s walk through the math with concrete examples.

Base Payment Structure

In Hong Kong Mahjong, payouts follow a doubling pattern based on faan:

Faan	Payment per Loser
3	$8
4	$16
5	$32
6	$64
7	$128
8+ (limit)	$256

(These are example amounts using a common base unit. Your table’s actual amounts depend on the agreed-upon base.)

Example 1: A 5-Faan Hand

Scenario A — Discard Win (5 faan):

Only the shooter pays: $32
Total received by winner: $32

Scenario B — Self-Drawn Win (5 faan + 1 faan zi mo = 6 faan):

Each of three players pays: $64
Total received by winner: $192

The self-drawn win earns 6 times more than the discard win in this case. That’s a massive difference.

Example 2: A 3-Faan Hand

Scenario A — Discard Win (3 faan):

Shooter pays: $8
Total: $8

Scenario B — Self-Drawn Win (3 faan + 1 zi mo = 4 faan):

Each of three pays: $16
Total: $48

Again, the self-drawn win pays 6 times the discard win.

Example 3: Near the Limit

Scenario A — Discard Win (7 faan):

Shooter pays: $128
Total: $128

Scenario B — Self-Drawn Win (7 faan + 1 zi mo = 8 faan, limit):

Each of three pays: $256
Total: $768

Now the self-drawn win pays 6 times more — and it hits the limit.

Why Self-Drawn Wins Are So Powerful

The math reveals two compounding factors:

Triple payment — Three players pay instead of one
Extra faan — The +1 faan bonus doubles the per-person amount

These multiply together, making self-drawn wins significantly more valuable. This is why experienced players often aim for a self-drawn finish when they’re one tile away (聽牌 / ting pai).

Strategic Implications

For the Winning Player

If you’re one tile away from winning, consider whether your winning tile has already been discarded. If copies are in the discard piles, your chances of drawing it yourself decrease.
Sometimes it’s worth waiting an extra turn for a self-drawn win rather than immediately claiming a discard, especially with a high-faan hand.
But don’t get greedy — a discard win beats no win at all.

For Defending Players

If someone is clearly close to winning (one away), be extremely careful with your discards.
It’s sometimes safer to let them self-draw than to risk being the shooter. If they self-draw, you share the cost with two other players. If you shoot them, you pay alone.
This is the foundation of defensive play in mahjong.

The Shooter’s Dilemma

Being the shooter is the worst outcome for the losing side. You pay 100% of the cost instead of 33%. This is why defensive discarding is such an important skill — avoiding being the one who throws the winning tile.

Special Cases

Robbing a Kong (搶槓)

If a player tries to add a tile to an existing revealed pung to make a kong, and that tile would complete your hand, you can “rob the kong” and declare a win. This is treated as a discard win, with the kong-declaring player as the shooter.

Last Tile Win (海底撈月)

Winning on the very last tile drawn from the wall gets an additional faan bonus. If it’s a self-draw of the last tile, the bonus stacks with the regular self-drawn bonus.

Dealer Bonus

When the dealer (East) wins, all payments are typically multiplied by 1.5x. When the dealer loses, they pay 1.5x. This applies to both win types.

Quick Reference: Discard vs Self-Drawn

Factor	Discard Win	Self-Drawn Win
Who pays	Shooter only	All 3 opponents
Bonus faan	None	+1 faan (自摸)
Risk to losers	High (for shooter)	Shared evenly
Strategic value	Good	Great
Typical total payout	1x	~6x

FAQ

Is it always better to self-draw?

In terms of payout, yes — self-drawn wins are always worth more. But you can’t always control whether you draw the tile or someone discards it. Don’t pass up a discard win hoping for a self-draw unless you have a strong reason.

Does the self-drawn bonus always apply?

Yes, in standard Hong Kong Mahjong rules, a self-drawn win always earns +1 faan. Some house rules may modify this, but it’s virtually universal.

What if two players can win from the same discard?

In standard rules, if multiple players can win from the same discard, the player closest in turn order (counterclockwise from the discarder) gets priority. Some groups allow multiple winners from a single discard — clarify this before playing.
