Understanding the Basic Objective and Game Flow

Mahjong is a tile-based game played by four players that combines elements of skill, strategy, and chance. The primary goal is to be the first player to form a winning hand by collecting specific combinations of tiles. Unlike many Western card games, mahjong emphasizes pattern recognition and tactical decision-making throughout the entire match.

The game uses 144 tiles divided into several categories. There are three main "suits" similar to playing card suits: Bamboo (represented by bamboo stalks), Characters (represented by Chinese numerals), and Dots (represented by circular symbols). Each suit contains tiles numbered 1 through 9, with four copies of each tile in play. Beyond the numbered suits, the game includes Honor tiles, which consist of four Wind tiles (East, South, West, North) and three Dragon tiles (Red, White, Green), with four copies of each as well.

A typical game proceeds through several rounds, with players taking turns drawing and discarding tiles. Each player begins with 13 tiles, and on their turn, they draw one additional tile, bringing their hand to 14 tiles temporarily. They then must discard one tile to return to a waiting state of 13 tiles. The winner is the player who completes a legal hand by forming specific combinations before other players do.

Understanding the flow of play is essential before learning specific rules. Players sit in predetermined positions, and the game moves in a counterclockwise direction around the table in most traditional versions. The concept of "melds" (sets of matching tiles) and the strategic timing of when to claim discarded tiles versus waiting for a draw both influence how games develop.

Practical Takeaway: Before playing, familiarize yourself with the 144-tile composition and remember that the core objective involves collecting tiles to form winning patterns before other players do. The sequential turn structure and passing of tiles follow a predictable rhythm that becomes natural with practice.

The Four Types of Tile Combinations and Hand Patterns

Mahjong hands are built from four fundamental types of tile combinations, each serving as a building block for successful play. Understanding these combinations is critical because a legal winning hand must contain specific patterns that adhere to strict rules.

The first combination type is called a "Pung" (or "Pung"), which consists of three identical tiles. For example, three 5-Dot tiles form a Pung. This is one of the most common combinations in mahjong. The second type is a "Kong," which is four identical tiles. Kong combinations are powerful and relatively rare, as they require collecting all four copies of a single tile. Players can form a Kong from their hand, or they can claim a Kong through specific gameplay mechanics that occur later in the round.

The third combination is a "Chow" (or "Sequence"), which consists of three consecutive numbered tiles from the same suit. For example, 3-Bamboo, 4-Bamboo, and 5-Bamboo form a valid Chow. A crucial rule about Chows is that they can only be formed from numbered tiles (1-9 in any suit), never from Honor tiles like Winds or Dragons. Players must understand that a Chow like 8-Character, 9-Character, 1-Character is not valid because it wraps around the sequence.

The fourth combination type is a "Pair," consisting of two identical tiles. A legal winning hand must contain exactly one Pair. This means a winning hand always has this structure: four combination sets (each being either a Pung, Kong, or Chow) plus one Pair, totaling 14 tiles.

Most traditional mahjong variations require a winning hand to follow this pattern: Pung + Pung + Pung + Pung + Pair (for example), or Kong + Chow + Chow + Pung + Pair, or any other valid combination of four melds plus one pair. Some variations include special hand patterns with different requirements, but the basic four-meld-plus-pair structure remains standard.

Practical Takeaway: Memorize the four combination types: Pung (3 identical), Kong (4 identical), Chow (3 consecutive numbered tiles from one suit), and Pair (2 identical). Every legal winning hand contains exactly four of these melds plus one Pair, totaling 14 tiles. Practice identifying these patterns in sample hands before playing with experienced players.

Initial Setup and the Distribution of Tiles

Setting up a mahjong game properly ensures fair play and establishes the foundation for a smooth game session. The setup process involves determining player positions, shuffling and stacking tiles, and distributing the initial hand to each player.

Four players sit around a square or rectangular table, with designated positions named after compass directions: East, South, West, and North. The East position is considered the most important and typically begins the game as the dealer. In many variations, the East position also has specific advantages or special scoring rules. Players may determine who sits where through random selection or by agreement before play begins.

All 144 tiles are placed face-down on the table and thoroughly shuffled. Players then work together to build a "wall" consisting of stacked tiles. Each player builds a section of the wall in front of their seating position. The wall typically consists of tiles stacked two high and arranged in two rows of 18 stacks each, creating a rectangular structure around the center of the table. In some variations, players build walls of different dimensions, so confirming the specific variant being played is important.

The dealer (East player) rolls two dice to determine where tile drawing begins. Based on the dice result, a specific position on the wall is identified as the starting point. The dealer draws two tiles from this position (taking the top tile and then the bottom tile from a stack), then each subsequent player in counterclockwise order draws two tiles at a time until each player has 12 tiles. The dealer then draws one additional tile, giving them 14 tiles total, while other players hold 13 tiles each.

After the initial distribution, players organize their tiles (keeping them face-up and visible only to themselves) and examine their hands to assess potential patterns and strategies. The dealer then plays first by discarding one tile face-up in the center of the table, where it becomes available for other players to claim.

Practical Takeaway: Practice the wall-building process and tile distribution routine several times before playing competitively. Proper setup ensures the game starts correctly. Remember that the dealer receives 14 tiles while other players receive 13, giving the dealer a first-move advantage that alternates among players across multiple rounds.

Drawing, Discarding, and Claiming Tiles During Play

The core gameplay mechanics of mahjong revolve around drawing tiles from the wall, discarding unwanted tiles, and claiming tiles that other players have discarded. Mastering these mechanics is essential to playing competent mahjong.

During each turn, a player must draw exactly one tile from the wall, typically from the next position in line following the established pattern from the initial deal. After drawing, the player examines all 14 tiles in their hand and must discard exactly one tile by placing it face-up in the center area of the table. This discarded tile remains visible to all players and becomes available for other players to claim through specific actions.

When another player discards a tile, the other three players have the opportunity to claim it, but only under specific conditions. A player may claim a discarded tile to complete a Pung (collecting three matching tiles, with the two already in their hand). A player may also claim a discarded tile to complete a Kong (collecting four matching tiles total). Additionally, a player may claim a discarded tile to complete a Chow, but only the player immediately following the discarder in turn order may claim a tile for this purpose in most traditional variations. These claiming actions are called "calling" a tile.

A critical rule states that a player may only claim a discarded tile to form a complete winning hand (called "calling meld" or "winning off the discard"). In this situation, any player, not just those following the discarder, may claim the discarded tile to win the round. This action takes precedence over other players' intentions to claim the same tile for other purposes.

If no player claims a discarded tile, it remains in the discard pile and play continues with the next player drawing from the wall and then discarding. If a
