Taiwanese Mahjong

1 History and Origins

Taiwanese Mahjong (台灣麻將, also called "16-tile Mahjong" or "Blood Bath Mahjong") developed in Taiwan and became the dominant form of Mahjong on the island. It differs substantially from both Hong Kong and Classical styles, incorporating elements that make the game faster, higher-stakes, and more chaotic.

The 16-tile hand size is the most immediately distinctive feature: players deal and hold 16 tiles, meaning hands are larger and more complex. The ability to win multiple times in a single round creates dramatic swings in fortune and gives the variant its informal "blood bath" nickname among enthusiastic players.

Taiwanese Mahjong is popular in Taiwan, among Taiwanese diaspora communities worldwide, and has influenced rules in nearby regions. It is also sometimes called "Big Two Mahjong" or described simply as "the Taiwanese style" to distinguish it from Cantonese/Hong Kong rules.

2 The Tiles

Standard Taiwanese Mahjong uses 144 tiles: 108 suited tiles (Bamboo, Circles, Characters 1-9, four each), 16 wind tiles, 12 dragon tiles, and 8 bonus tiles (4 flowers, 4 seasons). Some sets include additional special tiles.

Flower and season tiles in Taiwanese Mahjong are drawn from the live wall (not the dead wall) as replacement tiles. When you draw a flower or season, set it aside, draw another tile from the live wall to replace it, and continue. This means the live wall depletes faster and the game is shorter per round.

3 Setup: The 16-Tile Hand

The key difference from other styles: each player holds 16 tiles (not 13) throughout the game.

1. Shuffle all 144 tiles. Build walls (36 tiles per player, 2 high, 18 wide, to accommodate the extra tiles).
2. Assign seat winds: East (dealer), South, West, North counterclockwise.
3. Break the wall by dice roll. Deal 4 tiles per round, four rounds (16 tiles each). Or deal 4 at a time for 3 rounds (12), then 4 more to reach 16.
4. The dealer does not draw an extra tile before discarding. All players start with 16 tiles. The dealer discards one tile to begin.
5. Handle any bonus tiles drawn: reveal, set aside, and draw replacement from the live wall.

Hand size: Players maintain 16 tiles in hand at all times (minus any open face-up melds). This means each player seeks to complete 5 melds plus 1 pair (total 17 tiles, with 1 discarded) or alternative structures that use all 16+1 tiles.

Wait: a standard Taiwanese winning hand is 16 tiles arranged as 5 melds (sets of 3) plus 1 pair (2 tiles) = 17 tiles total. The winning tile (drawn or claimed) is the 17th tile.

4 Turn Structure

Same basic flow as other variants: draw from the wall, then discard. Other players may claim discards for win, kong, pong, or chow. Play moves counterclockwise.

Claiming priority: win (highest), kong, pong, chow (next player only). When a claim is made, the claimer completes their meld face-up and discards one tile. Play continues from the player to the right of the discarder (not next in seat order).

Flower tile replacement: Drawn from the live wall (not the dead wall as in Hong Kong rules). Continue drawing from the live wall until you get a non-bonus tile.

5 Scoring: Tai System

Taiwanese Mahjong uses "tai" (台) as the scoring unit. Each tai doubles or multiplies the base payment. Payments are agreed in advance (e.g., 1 tai = NT$100 or equivalent).

Minimum Tai

Most Taiwanese groups require a minimum of 1 tai (or sometimes 3 tai) to win. Check house rules before playing.

Common Tai Sources

Payment: 1 tai = 1 unit of agreed currency. 2 tai = 2 units. Tai do not double exponentially in the Hong Kong faan sense; they typically add linearly or multiply by a fixed factor depending on house rules. Some groups treat each tai as a doubling (similar to faan); clarify before playing.

Dealer Payment

The dealer pays and collects more than non-dealers. Exact multiplier varies: common house rules are dealer pays/collects 1.5x or 2x. Check local rules.

6 Multiple Winning (Bao)

The most dramatic feature of Taiwanese Mahjong: a single player can win multiple times in one round. There is no limit on how many times you can win. This is sometimes called "blood bath" rules because a single player can collect from all three opponents repeatedly in the same round if they are on a winning streak.

After a player wins:

1. Payment is settled. The winner collects from the discarder (on discard win) or all three opponents (on self-draw win).
2. The hand is reshuffled and re-dealt. OR, in some rule sets, only the winner re-deals a new hand and the other players keep adjusted tile counts.
3. The game continues until the round ends (dealer passes) or a set number of rounds is completed.

Specific house rules for multiple winning vary significantly. Common variations: winner must deal next hand; stakes double after each consecutive win by the same player; each win in a round is counted and tallied for final settlement.

7 Special Hands

Taiwanese Mahjong includes additional special hands beyond the standard limit hands:

• Thirteen Orphans: One each of all terminal and honor tiles plus one duplicate. Maximum payment.
• Seven Pairs: Seven different pairs (14 tiles). Valid as a special hand in Taiwanese rules. Scores extra tai.
• All Green: Hand of only Bamboo tiles that are green in color (2, 3, 4, 6, 8 Bamboo) plus optionally Green Dragon.
• Pure One Suit: 5 melds and 1 pair all in one suit. High tai value.
• All Honors: 5 melds of wind/dragon tiles plus honor pair.
• Earth Hand: Dealer wins on their initial discard's claim (first tile discarded in the round).
• Heaven Hand (Tianhu): Dealer wins on the very first draw without discarding. Maximum payment.

8 Dealer Advantages

The dealer position in Taiwanese Mahjong carries significant advantages beyond paying/collecting more:

• Dealer retains seat on any win, not just when they win. If no one wins a round, the dealer also retains. The dealer seat only passes when another player wins.
• Dealer's Heaven Hand: If the dealer has a complete winning hand with their initial 16 tiles (before any discards), they declare Tianhu and collect maximum payment from all three opponents.
• Extended dealer rounds: Because the dealer retains on draws as well as wins, strong dealers can accumulate many consecutive hands and collect higher and higher payments if stakes escalate with rounds.

9 Strategy

Embrace the larger hand. With 16 tiles, you have more flexibility than in 13-tile variants. You can often pursue two semi-complete hand shapes simultaneously and decide which to complete based on what you draw or can claim.

Track flower tiles carefully. Since replacement draws come from the live wall, early flower tiles reduce the wall significantly. Players with many flowers early get closer to their winning hand but shorten the game for everyone.

Multiple-win rounds reward aggression. If you win once, you may win again in the same round. Push for complete hands rather than waiting for marginally better hands. Speed and quantity of wins often matter more than maximizing tai per hand.

Dealer defense matters most. With a strong dealer running hot, the other three players should coordinate discards to avoid feeding the dealer winning tiles. Tracking what the dealer has exposed tells you which tiles to hold back.

Concealed hand bonuses are worth protecting. The extra tai for a fully concealed hand is significant. Avoid claiming unless the speed benefit is overwhelming.

10 Common Misconceptions

• "Taiwanese Mahjong uses 13 tiles like other styles." No. Hands are 16 tiles, requiring 5 melds plus 1 pair (17 tiles with the winning tile).
• "Flower tiles replace from the dead wall." In Taiwanese rules, flowers are replaced from the live wall, unlike Hong Kong rules where the dead wall is used.
• "You can only win once per round." Taiwanese rules allow multiple wins per round by the same player.
• "Tai are the same as faan." They play a similar role but are implemented differently. In many Taiwanese groups, tai add linearly rather than doubling exponentially. Confirm house rules.

11 Frequently Asked Questions

Why 16 tiles instead of 13?

The 16-tile hand is a distinctive Taiwanese tradition that allows larger, more complex winning hands with 5 melds instead of 4. It creates longer, more strategic hand-building phases.

What is a "tai" worth?

Tai are the scoring unit agreed upon before play. Common values range from NT$10 to NT$100 per tai in casual games. High-stakes games can go much higher. Some groups treat each tai as doubling (like faan); others add them linearly. Agree beforehand.

Can the dealer ever lose the seat voluntarily?

No. The dealer retains the seat after winning a hand or after a draw. The seat only passes when another player wins.

Is Seven Pairs a valid hand in Taiwanese Mahjong?

Yes, in most Taiwanese rule sets. Seven pairs (7 unique pairs = 14 tiles) is a valid special hand with its own tai value, typically 1-2 tai above the minimum.

How many rounds are in a full Taiwanese game?

Typically one East round (until each player has been dealer at least once). Many groups play just one dealer rotation. High-stakes groups may play East + South rounds.

What is the maximum tai possible?

Depends on house rules, but some groups play with a cap (e.g., 8 or 10 tai maximum). Limit hands pay a fixed maximum regardless of calculated tai.

How does self-draw payment work?

On a self-draw (Zimo) win, all three opponents each pay the winning player based on the hand's tai value. The dealer pays more (1.5x or 2x by house rules). This is why self-draw wins are so valuable.

Are there different rules for claiming in Taiwanese Mahjong?

Priority is the same: win beats kong beats pong beats chow. Chow can only be claimed by the player who draws next (left neighbor). In some Taiwanese groups, chow to win is allowed; in others it is not. Check house rules.
