Mahjong Scoring Guide: Fan Patterns, Stacking, and Payouts Explained

Sichuan Blood Battle Mahjong uses an exponential fan scoring system. Every fan pattern you qualify for doubles your payout. Win with 1 fan and you earn 2× base. Win with 4 fan and you earn 16× base. Stack multiple patterns and your earnings can multiply dramatically — all in a single hand. This guide covers every fan pattern, how they combine, and the strategies to chase high-value wins.

1. How Scoring Works: The Fan Formula

Every room has a base rate. When you win, you collect:

Payout = Base Rate × 2^{total fan}

Fan patterns are additive: add up every qualifying pattern in your winning hand, then apply the exponent. The table below shows how fast payouts grow:

Fan Count	Multiplier	Example at 1,000 base
1 fan	2×	2,000
2 fan	4×	4,000
3 fan	8×	8,000
4 fan	16×	16,000
5 fan	32×	32,000
6 fan	64×	64,000

2. Who Pays: Self-Draw vs. Discard Win

ℹ️ Self-Draw vs. Discard Win

Self-Draw : You draw the winning tile from the wall. Every active opponent pays you the full payout. With 3 opponents, you collect the payout 3 times total.
Discard Win : An opponent discards your winning tile. Only that one player pays you the full payout.

This means a self-draw win is worth up to 3× more total coins than the same hand won by discard. Always build toward self-draw when you can.

3. Fan Pattern 1 — Ping Hu · 1 Fan

Ping Hu is the all-sequences win: your hand contains four sequences and one pair, with no triplets or exposed Pong melds. You must win with a closed hand — you cannot have made any Pong declarations. Ping Hu is the most common pattern and the foundation of fast, aggressive play.

Why aim for Ping Hu? It does not restrict which tiles you chase, making it easy to reach tenpai quickly. Combined with the Men Qian Qing bonus (closed self-draw), a Ping Hu self-draw hand earns 3 fan total — a solid 8× payout from a standard, flexible hand.

Ping Hu example: 1-2-3 wan, 4-5-6 wan, 3-4-5 tong, 6-7-8 tong + pair 9-9 tong (void suit = tiao)

💡 Ping Hu Strategy

Keep your hand closed. The moment you Pong, you lose Ping Hu eligibility. Sequences are flexible — a 4-5-6 block can complete with many tiles — so closed hands reach tenpai faster than Pong-heavy hands.

4. Fan Pattern 2 — Peng Peng Hu · 2 Fan

Peng Peng Hu (All Triplets) requires every one of your four sets to be a triplet or Kong — no sequences at all. Your pair can be anything. Because each set requires three of the same tile, this hand demands either aggressive Ponging or the luck of drawing triplets naturally.

At 2 fan, Peng Peng Hu gives a 4× multiplier on its own. Combined with Qing Yi Se (same suit), the total reaches 6 fan — 64× base rate. That is one of the highest practical scoring combinations in the game.

Peng Peng Hu: 3-3-3 wan, 6-6-6 wan, 9-9-9 wan, 2-2-2 tong + pair 5-5 wan (void suit = tiao)

5. Fan Pattern 3 — Seven Pairs · 2 Fan

Seven Pairs is an alternative winning structure: your 14 tiles form exactly 7 pairs. No sets, no Kongs — just pairs. This earns 2 fan (4× base) and plays very differently from standard hands. Because you never Pong, your hand stays fully closed, making it hard for opponents to read.

The strategy for Seven Pairs is patience and defense. You need 7 specific pairs, which means holding tiles and waiting for matches. Discard tiles that have no pair potential early, and protect your pairs from being discarded.

Seven Pairs : 7 pairs across wan and tong suits (void suit = tiao)

6. Fan Pattern 4 — Qing Yi Se · 4 Fan

Qing Yi Se (Pure Suit) is the most powerful standard fan pattern: every tile in your hand must be the same suit. Four sequences or triplets plus the pair — all from one suit. At 4 fan, this gives a 16× multiplier before any bonuses.

Since Blood Battle requires you to void one suit, you are already restricting to two suits. Qing Yi Se takes that further — you focus entirely on one. Pair Qing Yi Se with a self-draw and the Men Qian Qing bonus for a possible 6 fan total (64× base).

Qing Yi Se (all wan): 1-2-3, 3-4-5, 5-6-7, 7-8-9 wan + pair 4-4 wan (void suits = tiao + tong)

💡 The Strongest Practical Path

Qing Yi Se is achievable in most rounds if you commit to one suit from the exchange phase. Void both other suits mentally (you only officially void one, but keep only your target suit). When you reach tenpai in a pure-suit hand, even a discard win at 4 fan earns 16× base.

7. Fan Pattern 5 — Long Seven Pairs · 4 Fan

Long Seven Pairs combines Qing Yi Se and Seven Pairs: all 14 tiles form 7 pairs and they are all from one suit. This is the rarest and highest base-value pattern in the game. At 4 fan on its own, a self-draw Long Seven Pairs with Men Qian Qing reaches 6 fan — 64× base, collected from all 3 opponents.

Long Seven Pairs (all tong): 7 pairs, all tong suit (void suits = wan + tiao)

8. Bonus Fan Patterns

These patterns add +1 fan each on top of your base hand pattern. They can all stack with each other and with the main patterns above.

Men Qian Qing — +1 Fan

You win by self-draw with a fully closed hand — no Pong or open Kong declarations. This is the single most accessible bonus fan: simply keep your hand closed and draw your own winning tile. Combined with Ping Hu or Qing Yi Se, Men Qian Qing pushes the hand up by one full doubling tier.

Hai Di Lao Yue — +1 Fan

You win by drawing the very last tile from the wall. Because the wall is finite (108 tiles total), the last draw is a rare and celebrated event. If you are still alive in the end game and on tenpai, there is always a chance the last tile completes your hand.

Gun Guo He — +1 Fan

You win on the replacement draw after a Kong. When you declare a Kong, you draw an extra tile from the dead wall. If that tile completes your hand, you receive the Gun Guo He bonus. Declaring Kongs aggressively when you are close to tenpai increases your chances of triggering this bonus.

9. Fan Stacking: Combined Patterns

Fan patterns add together before the exponent is applied. Here are the most powerful achievable combinations and their total payouts:

Pattern Combination	Total Fan	Multiplier	Example at 1,000 base
Ping Hu	1 fan	2×	2,000
Ping Hu + Men Qian Qing	2 fan	4×	4,000
Ping Hu + Men Qian Qing (self-draw, ×3 opp.)	2 fan	4×	12,000 total
Peng Peng Hu	2 fan	4×	4,000
Qing Yi Se	4 fan	16×	16,000
Qing Yi Se + Men Qian Qing	5 fan	32×	32,000
Qing Yi Se + Men Qian Qing (self-draw, ×3)	5 fan	32×	96,000 total
Qing Yi Se + Peng Peng Hu (theoretical)	6 fan	64×	64,000
Long 7 Pairs	4 fan	16×	16,000
Long 7 Pairs + Men Qian Qing (self-draw)	5 fan	32×	96,000 total

💡 Self-Draw Triples Your Total Earnings

On a 5-fan self-draw hand (32×) at a 1,000 base room, each opponent pays 32,000 coins. With 3 opponents you collect 96,000 in a single hand. That is nearly 100× the base rate. This is why chasing self-draw is always worth the extra effort.

10. Strategy: When to Chase High Fan vs. Just Win

High-fan hands take longer to build. The question is always: is the extra time worth the extra payout? Here are the key decision points:

Early game (first 10 discards): Always aim for at least Qing Yi Se if your hand allows it. You have time. A 4-fan hand is 16× base vs. 2× for a 1-fan win — that difference is massive.
Mid-game (10–20 discards): If you are not close to tenpai for a high-fan hand, fall back to a simpler pattern. Being on tenpai at 1 fan is better than holding a half-finished 4-fan hand.
Late game (last 10 tiles): Get to tenpai at any cost. Even a 0-fan win at end of wall protects you from the Flower Pig penalty.
After first player wins: Increase aggression. You need to win before the wall runs out. Simplify your target hand if needed.

11. Flower Pig Penalty

If the round ends — either because 3 players win or the wall runs out — and you are still holding any tiles from your declared void suit, you become a Flower Pig . You must pay every player who is currently in tenpai (waiting to win) a penalty payment, in addition to any other end-of-wall settlements.

⚠️ Flower Pig: The Worst Outcome

The Flower Pig penalty can cost more coins than losing several normal hands. Always discard your void suit tiles as your first priority — even before building your winning hand. Never hold onto void tiles hoping for a better discard opportunity later.

FAQ

Q1. What is the most valuable fan pattern in Blood Battle Mahjong?

Qing Yi Se (all same suit) and Long 7 Pairs (7 pairs all same suit) both score 4 fan (16× base) on their own. With bonus patterns stacked, both can reach 5–6 fan. Long 7 Pairs is rarer; Qing Yi Se is more achievable since you can use sequences.

Q2. Can I have both Ping Hu and Peng Peng Hu in the same hand?

No. Ping Hu requires all sequences; Peng Peng Hu requires all triplets. They are mutually exclusive — you cannot have both at once.

Q3. Does Qing Yi Se require a closed hand?

No. Qing Yi Se only requires every tile (including exposed Pong and Kong melds) to be the same suit. You can Pong freely and still qualify. This makes it more achievable than Ping Hu for players who Pong aggressively.

Q4. What is Men Qian Qing and how does it add fan?

Men Qian Qing means you win by self-draw with a completely closed hand — no Pong or open Kong declarations made during the round. It adds +1 fan on top of your main pattern. It stacks with everything: Ping Hu + Men Qian Qing = 2 fan; Qing Yi Se + Men Qian Qing = 5 fan.

Q5. What is the Flower Pig penalty?

If the round ends and you are still holding any tiles from your declared void suit, you become a Flower Pig. You must pay a penalty to every player who is currently in tenpai. Always discard void suit tiles as your first priority to avoid this outcome.

Q6. Is self-draw always better than a discard win?

In total payout, yes. Self-draw collects from all active opponents (up to 3), while a discard win collects only from the one discarder. A 4-fan self-draw at 1,000 base collects 16,000 from each of 3 opponents = 48,000 total. The same hand on a discard win = only 16,000.

Q7. Can fan patterns stack with each other?

Yes. Fan values are additive — you add all qualifying patterns together, then apply the exponent. Qing Yi Se (4) + Men Qian Qing (1) = 5 fan = 32× base. There is no cap on stacking in standard play.
