Sichuan Mahjong

1 History and Origins

Sichuan Mahjong (四川麻将, Sichuan Majiang) is the dominant style in Sichuan province in southwest China, and one of the most distinctive regional variants in existence. While most regional variants differ mainly in scoring and bonus tiles, Sichuan Mahjong differs fundamentally in its core tile set and claiming rules.

The variant developed in Sichuan's capital Chengdu, where Mahjong is an integral part of local culture. Chengdu's famous teahouse culture and slower pace of life are associated with long Mahjong sessions. The local style evolved to be faster per hand while remaining deeply strategic through the emphasis on hand efficiency without the shortcut of claiming opponents' discards.

Several sub-styles of Sichuan Mahjong exist, including Bloody Rules (Xuezhan Dao Di), where play continues after the first win until all players have won or the wall runs out. The game has become popular online through Mahjong apps targeting Chinese players and has attracted international interest from strategy enthusiasts.

2 The Tiles (108 Total)

Sichuan Mahjong uses only the three suit tiles. No honor tiles at all.

• Characters (Wan): 1-9, four copies each = 36 tiles
• Bamboo (Tiao): 1-9, four copies each = 36 tiles
• Circles (Tong): 1-9, four copies each = 36 tiles

Total: 108 tiles. No winds. No dragons. No flowers. No seasons. No bonus tiles of any kind in the standard version.

Some rule sets include flower/season tiles as optional bonuses, but the core game is played without them. The stripped-down tile set intensifies the focus on number patterns and suit purity.

3 Setup

1. Shuffle all 108 tiles face-down.
2. Each player builds a wall of 27 tiles (2 high, 13-14 wide, adjusted for 108 total tiles across 4 players).
3. Assign dealer (East) and seat order counterclockwise.
4. Deal 13 tiles to each player. Dealer draws 1 extra tile (14 total) and discards to begin.
5. No dead wall is needed in most Sichuan rules since there are no bonus tiles requiring replacement, and kongs (if allowed) draw from the live wall end.

4 Turn Structure: Draw-Only Rules

This is the most unusual feature of Sichuan Mahjong compared to all other major variants:

You cannot claim discards to form melds (pong, chow, or kong). On your turn, you always draw from the wall. The only time you may claim a discard is to win (declare Mahjong).

1. Draw: Take one tile from the live wall. Always. You never take from the discard pile to build sets.
2. Win or discard: If your hand is complete, declare Mahjong. Otherwise discard one tile face-up.
3. Win from discard: Any player may claim the discarded tile ONLY if it completes their winning hand. They cannot claim it to form a pong or chow.

This means:

• There are no face-up melds (exposures). All 13 tiles remain concealed in hand throughout.
• There is no need for claiming priority rules for pong/chow, since neither is possible.
• The game is entirely self-directed. You build your own hand from wall draws.
• Discards are only relevant if they complete another player's hand.

Kong rules in Sichuan: Some rule sets allow declaring a kong when you draw the fourth copy of a tile you already have three of in hand. Draw a replacement from the live wall. Some rule sets disallow kongs entirely. Check house rules.

5 Winning Conditions

A standard winning hand: 4 melds (sequences of 3 or triplets of 3) plus 1 pair = 14 tiles. Same structure as other variants.

The winning tile may be:

• Self-drawn (Tsumo/Zimo): You draw the winning tile from the wall.
• Discarded by an opponent: The tile completes your hand. You claim it and declare Mahjong.

Suit purity requirements: Many Sichuan rule sets require the winning hand to use tiles from no more than two suits, or even just one suit. "Qing Yi Se" (pure one suit) requirements vary by local rules. Some groups allow any combination of the three suits; others require suit restriction. Confirm before play.

Minimum requirement: Many Sichuan groups have no minimum point requirement for the basic hand, or a simple requirement of having a specific suit combination. The absence of honor tiles means traditional faan-from-honors strategies do not apply.

6 Scoring

Sichuan Mahjong scoring varies by local rules, but common frameworks:

Scoring by Hand Type

Payment is typically: discard win, the discarder pays; self-draw win, all three opponents pay. Dealer pays/collects double in most Sichuan rule sets.

Xuezhan (Bloody Rules) Scoring

In the Xuezhan (Blood Battle) variant, the game continues after each win until all players have won or the wall runs out. Scoring accumulates across all wins in the round. A player who wins first gets their payment, then the round continues for remaining players. The last player standing who has not won typically pays additional penalties.

7 Multiple Winners

Sichuan Mahjong commonly allows multiple players to win in the same round (Xuezhan/Bloody Rules):

1. First player to win declares Mahjong. Payment is settled (discarder pays or all opponents pay for self-draw).
2. The round continues. The winning player may stay in or drop out, depending on house rules.
3. If another player then wins, payment is settled again.
4. The round ends when all players have won, or the wall is depleted, or a time/hand limit is reached.

A player who wins but whose winning tile came from a player who already won may have adjusted payment rules. Some groups require that once you win, you cannot collect from players who have already won in the same round. Check house rules for payment structure in multiple-win rounds.

8 Special Hands

• Qing Yi Se (Pure One Suit): The entire hand in one suit. High payment, typically 4-8x base value. Since honors are removed from the game, this is the primary premium hand in Sichuan.
• All Pung (Dui Dui Hu): Four triplets plus a pair, no sequences. Worth 2-3x base value typically.
• All Sequences (Ping Hu): Four sequences plus a pair, no triplets. Basic hand, standard payment.
• All Terminals (Qing Lao Tou): Four triplets of only 1s and 9s (since honors are absent, terminals are the closest to honor tiles in difficulty). Maximum or near-maximum payment.
• Nine Gates: 1-1-1-2-3-4-5-6-7-8-9-9-9 all in one suit, fully concealed. Maximum payment.
• Seven Pairs: Seven unique pairs (14 tiles). Valid in many Sichuan rule sets.

9 Strategy

Suit Commitment is Critical

Without honors tiles creating natural hand anchors, the most important strategic decision in Sichuan Mahjong is which suit or suits to build in. In rules that require suit purity to win big, committing to one suit early and discarding the other two aggressively is the dominant strategy.

Tile Efficiency Over Everything

Since you cannot claim discards for melds, every tile in your hand came from your wall draws. Hand building is purely about how efficiently you convert draws into completed melds. Count how many tiles advance your hand ("outs") and discard whatever reduces your outs least.

Discard Reading is Different

In Sichuan, discards tell you less about opponents' hands since they cannot be claimed for melds. But discards still show what suits opponents are abandoning. If three players are dumping Bamboo tiles, Bamboo may be plentiful in the wall, which either helps or hurts your Bamboo-focused hand depending on how many you need.

No Defense Through Safe Tiles in the Same Way

In Hong Kong or Riichi, discarding a "safe" tile (one already discarded by the player you fear) prevents them from winning on it again. In Sichuan, the same logic applies only for win prevention: safe tiles are tiles you know your opponent cannot use as a winning tile. Since there is no claiming for melds, the only danger is being the discarder of the winning tile.

Pure Flush Payoff

If you draw several tiles early in one suit, committing hard to Qing Yi Se (pure flush) is often correct. The payout multiplier for a pure flush is much higher than a mixed hand. Even if pure flush is harder to achieve, the expected value calculation often favors the committed approach.

Kong Decision

Where kongs are allowed: declaring a kong gives you an extra draw. But it also slightly reveals your hand (the four tiles are shown). In a game where all hands are normally concealed, a kong is a meaningful information leak. Only declare kongs when the extra draw is critical or when the hand is already near complete.

10 Sichuan vs Other Variants

11 Common Misconceptions

• "You play Sichuan Mahjong with 144 tiles." No. Standard Sichuan uses 108 tiles (no honors, no bonus tiles). The smaller tile set is fundamental to the style.
• "You can pong from another player's discard." No. In Sichuan, the only time you may take a discard is to win the hand. No claiming for melds of any kind.
• "Without honors, the game is simpler." Removing honors and claims actually increases the emphasis on tile efficiency and pattern recognition. The game rewards deep understanding of suit structure.
• "The game ends after the first player wins." In Xuezhan (Bloody Rules), common in Sichuan, the round continues after the first win. Multiple players can win in the same round.

12 Frequently Asked Questions

Can I take discards in Sichuan Mahjong?

Only to win. You cannot claim a discard to form a pong, chow, or kong. All melds must be built from wall draws.

How many tiles are used in Sichuan Mahjong?

108: only the three suited suits (Bamboo, Circles, Characters), values 1-9, four of each. No winds, dragons, flowers, or seasons in the standard game.

What is Xuezhan (Bloody Rules)?

Xuezhan (Blood Battle/Bloody Rules) is a Sichuan variant where play continues after the first player wins. The round continues until all players have won or the wall is empty, allowing multiple winners per round.

Is Qing Yi Se (pure one suit) required to win?

Not always, but it is the premium hand. Some rule sets require the winning hand to use tiles from at most two suits. Others allow any combination. Check house rules.

Can I declare a kong in Sichuan Mahjong?

Depends on house rules. Some groups allow self-drawn kongs (you have all four of a tile in hand or draw the fourth). Others disallow kongs entirely. When allowed, draw a replacement from the live wall end.

What is the minimum hand to win?

A complete hand (4 melds + 1 pair). Some rule sets have additional requirements like suit restrictions (at most 2 suits) or a minimum scored value. Check local house rules.

Why are there no honor tiles?

Sichuan Mahjong evolved locally with a preference for pure suit-based play. Removing honors simplifies the tile set and increases the density of playable tiles per suit, changing the game's strategic focus entirely.

How does self-draw payment work?

On a self-draw win, all three opponents each pay the winner. In Xuezhan, a player who wins by self-draw after other players have already won collects from the remaining players who have not yet won (and possibly from those who have, depending on house rules).

Is Sichuan Mahjong good for beginners?

The no-claims rule removes the complexity of discard priority and open meld management, making the turn structure simpler. However, the strategic depth of hand building without claiming shortcuts is challenging in a different way. Good for experienced players who want a fresh challenge.

Can I win with Seven Pairs in Sichuan Mahjong?

In many Sichuan rule sets, yes. Seven unique pairs (14 tiles) is a valid special hand. Check with your group before play.
