Mahjong is a four-player tile game where players draw and discard tiles to build a complete hand of 14 tiles. A standard winning hand contains four sets (groups of three tiles) and one pair. The player who completes their hand first declares Mahjong and wins points from the other three players.
This guide covers everything you need to play your first real game: what the tiles are, how turns work, how to claim discards, and how winning works. If you’ve only played the phone tile-matching game, this is a different game entirely — and a much more interesting one.
The Tiles
A standard Mahjong set has 144 tiles across several categories.
Suit Tiles (108 tiles)
The three numbered suits form the backbone of most winning hands:
- Bamboo (Bam / 竹) — numbered 1 through 9, four copies of each (36 tiles)
- Characters (Wan / 萬) — numbered 1 through 9, four copies of each (36 tiles)
- Circles (Dots / 筒) — numbered 1 through 9, four copies of each (36 tiles)
Tiles numbered 1 and 9 in each suit are called terminals. Tiles numbered 2 through 8 are called simples. Terminals are harder to incorporate into sequences, which is why they appear in the discard pool early in most games.
Honour Tiles (28 tiles)
Honour tiles have no numerical value and cannot form sequences — they can only be used in pairs or pungs (three of a kind).
- Wind tiles — East (東), South (南), West (西), North (北) — four of each = 16 tiles
- Dragon tiles — Red (中 / Chun), Green (發 / Fa), White (白 / Baak) — four of each = 12 tiles
Bonus Tiles (8 tiles)
- Flowers — four tiles (Plum, Orchid, Chrysanthemum, Bamboo)
- Seasons — four tiles (Spring, Summer, Autumn, Winter)
When you draw a bonus tile, set it aside face-up and draw a replacement tile from the end of the wall. Bonus tiles add bonus points to your score in Hong Kong Mahjong but don’t count toward your hand structure.
Setting Up
Before dealing, players determine seating. This is typically done by rolling dice or drawing tiles. The player assigned East is the dealer for the first hand.
Building the wall: All 144 tiles are shuffled face-down and stacked into four rectangular walls (two tiles high, 18 tiles long), forming a square in the centre of the table. This is the wall that players draw from.
Dealing: The dealer draws 14 tiles; all other players draw 13. Play begins with the dealer.
The Goal: Building a Winning Hand
Your objective is to assemble a complete hand of 14 tiles. The standard structure is:
- Four sets (each set is a pung or a chow)
- One pair (two identical tiles)
Pung — Three identical tiles
Example: 🀇🀇🀇 (three 1-Bamboo tiles)
Chow — Three consecutive tiles in the same suit
Example: 4-Characters, 5-Characters, 6-Characters
Pair — Two identical tiles
Example: Two Red Dragon tiles
Some special hands deviate from this four-sets-one-pair structure and score extra. Those are covered in our Mahjong rules guide.
How a Turn Works
Play moves counter-clockwise around the table. On your turn:
- Draw one tile from the wall
- Assess whether the drawn tile improves your hand
- Discard one tile face-up to the centre
You always hold 13 tiles between turns. When you draw (or claim) the 14th tile that completes your hand, you win.
Drawing a Bonus Tile
If you draw a Flower or Season tile, set it aside face-up and draw a replacement tile from the opposite end of the wall (the “dead wall” or “kong box”). This replacement tile is your actual draw for the turn.
Claiming Discards — The Core of Mahjong’s Tension
When any player discards a tile, the other three players can potentially claim it — interrupting normal turn order. This is what makes Mahjong dramatically different from most card games.
Types of Claims
| Claim | What You Need | Who Can Claim |
|---|---|---|
| Pung | Two matching tiles in hand + discard = three of a kind | Any player |
| Kong | Three matching tiles in hand + discard = four of a kind | Any player |
| Chow | Two consecutive tiles + discard = sequence of three | Next player only |
| Mahjong | Discard completes your winning hand | Any player |
Claim Priority
When multiple players call at the same time:
Mahjong > Pung/Kong > Chow
If two players both call Mahjong on the same discard, the player closer to the discarder in turn order wins.
After Claiming
The claimed tile and its completed set are laid face-up on your side of the table — this is called melding. You then discard one tile to continue. Melded sets cannot be changed; they are locked in for the rest of the hand.
Strategic note: Melding reveals part of your hand to opponents. A concealed hand (no melded sets, won by self-draw) typically scores more, but you have to draw everything yourself.
Kong Rules
When you claim or draw a fourth tile to complete a kong (four of a kind):
- Lay all four tiles face-up (or three face-up, one face-down for a concealed kong)
- Draw a replacement tile from the dead wall
- Kongs count as one set but require you to have an extra tile to maintain hand size
Winning: Declaring Mahjong
When your 14-tile hand is complete, you declare Mahjong and reveal your full hand. Other players check it for validity.
Two Ways to Win
Self-draw (Zimo / Tsumo): You draw the winning tile from the wall yourself. All three other players each pay you based on the hand’s value.
Discard win (Ron): Another player discards the tile that completes your hand. That player alone pays you (in standard Hong Kong Mahjong). This is why experienced players are cautious about what they discard.
Self-draw wins typically score more than discard wins.
What Happens When the Wall Runs Out?
If all wall tiles are drawn and no one has won, the hand ends in a draw. The dealer re-deals and the same player remains dealer (no wind rotation occurs on a drawn hand in most variants).
Scoring Basics
Not all winning hands are equal. A hand’s value depends on its composition:
- All-pung hands (no sequences, only triplets) score significantly more than chow-heavy hands
- All-one-suit hands (e.g., all Bamboo tiles) score bonus points
- Concealed hands (won by self-draw with no melded sets) often earn extra
- Dragon pungs and seat/round wind pungs add points
- Rare special hands (all terminals, all honours, thirteen orphans) can pay enormous amounts
Losing players pay the winner based on the hand’s value. If you win by self-draw, all three pay. If you win on a discard, only the discarder pays (standard Hong Kong rules).
Common Beginner Mistakes
Locking onto one hand type — Beginners often decide on a hand they want and refuse to adapt when the tiles don’t come. Experienced players constantly reassess and pivot.
Claiming every pung — Melding a pung gains you a set but locks you in and broadcasts your intentions. Sometimes holding and keeping your hand concealed is stronger.
Ignoring the discard pool — The tiles other players throw away are free information. Before you discard each turn, glance at all three discard pools. Patterns will start speaking to you.
Feeding a winning player — When you sense an opponent is close (they’re discarding slowly, or their discard pool suggests a near-complete hand), switch to safe tiles. See our guide on reading the table.
Not tracking your seat wind — Your seat wind tile is worth more in a pung than other wind tiles. Knowing which wind is yours matters for scoring.
