How to Play Mahjong (Traditional Chinese Version)
This game rules guide explains the traditional Chinese Mahjong rules – perfect for beginners while providing a foundation for understanding other versions.
Preparations
- Players: 4 (adaptable for 2 or 3 casually)
- Components (144 tiles total):
- Dots (Circles): 1–9
- Bamboo (Bams): 1–9
- Characters (Craks): 1–9
- Wind tiles: East, South, West, North
- Dragon tiles: Red, Green, White
- Bonus tiles: Flowers & Seasons (optional)
Setup
- Players build a wall of tiles: 18 tiles long × 2 tiles high, forming a square.
- Each player draws 13 tiles, except the dealer (East), who starts with 14 tiles.
- The dealer begins by discarding one tile, starting the game.
Gameplay Overview
Mahjong is played in clockwise turns. Each turn, a player:
- Draws a tile (from the wall or by claiming a discard).
- Discards one tile to maintain a hand of 13 tiles.
The goal is to form a winning hand of 14 tiles.
Objective: Winning Hand
A standard winning hand consists of 14 tiles, typically arranged as:
- 4 sets (Pungs, Chows, or Kongs) + 1 pair
Types of Sets
| Set | Description | Example |
|---|---|---|
| Pung | 3 identical tiles | 🀇🀇🀇 |
| Chow | 3 consecutive numbers in the same suit (only claimable from the player to your left) | 🀄🀅🀆 |
| Kong | 4 identical tiles (requires drawing an extra tile) | 🀈🀈🀈🀈 |
| Pair | 2 matching tiles (required to complete hand) | 🀆🀆 |
Declaring Mahjong (Winning)
When you complete your 14-tile hand:
- Declare “Mahjong!” or “Hu”.
- Reveal your hand.
- The round ends immediately.
Winning can occur by:
- Self-draw → Drawing the winning tile from the wall.
- Claiming a discard → Taking the winning tile discarded by another player.
Claiming Discards
Players may claim a discarded tile to complete a set:
- Pung or Kong: Claimable from any player.
- Chow: Only claimable from the player to your left.
When claiming, reveal the completed set immediately. If multiple players want the same tile:
- Pung/Kong claims take priority over Chows.
Scoring (Simplified Chinese Mahjong)
Scoring varies across regions, but in classic Chinese Mahjong:
| Combination | Points |
|---|---|
| Pung of number tiles | 2 pts |
| Pung of honor tiles | 4 pts |
| Kong | 8 pts |
| Flowers & Seasons | +1 each |
| Bonus hands (All Pungs, Pure Suit, etc.) | Extra multipliers |
Tip: Many Mahjong sets include a scoring chart – keep it handy!
Winning the Game
Mahjong is usually played over multiple rounds, with the dealer role rotating in this order:
East → South → West → North.
- After all four players have been dealer once, that’s called a wind round.
- At the end of the session, the player with the highest total score wins.
