The most internationally popular variant, known for its accessibility and social gameplay
Hong Kong Mahjong (also called Cantonese Mahjong) is the most widely played variant worldwide and the standard taught in most Western countries. It emphasizes hand completion over complex scoring patterns, making it ideal for social play and beginners.
Bonus tiles are drawn, immediately revealed, placed aside, and replaced with a tile from the dead wall. They add points but are not part of the winning hand structure.
Standard winning hand: 4 sets + 1 pair = 14 tiles
Sets can be:
The pair (eyes) must be exactly two identical tiles.
Hong Kong Mahjong typically requires a minimum score to declare Mahjong:
Hong Kong Mahjong uses a "fan" system where each fan doubles the base payment. Scoring elements are cumulative.
Always keep the minimum scoring requirement in mind. Build hands that include at least one scoring pattern (all Pongs, mixed suit, dragons, etc.).
Decide early whether to go for a quick, low-scoring win or hold out for a high-value hand. Don't get stuck in between.
Keeping your hand concealed adds flexibility and scoring potential. Only call tiles when it significantly advances your position.
Pay attention to what's been discarded to calculate which tiles are still available and what opponents might be building.
A dynamic variant featuring joker tiles, continuous gameplay, and unique scoring patterns
Taiwanese Mahjong (also called Taiwanese 16-Tile Mahjong) is known for its fast pace, additional tiles, and continuous play style. The addition of joker tiles and flowers that count toward the winning hand creates a more flexible and dynamic game.
The defining feature of Taiwanese Mahjong:
Unlike Hong Kong style, flowers are integral to the hand:
Base: 4 sets + 1 pair = 14 tiles
Plus: Any flowers/seasons you've drawn
Final hand can be 16-17 tiles (14 main tiles + 2-3 bonus tiles)
East wind continues as dealer until they lose:
Taiwanese Mahjong uses "tai" (similar to fan). Common minimum is 4-5 tai to win.
Most Taiwanese games require 4-5 tai minimum to declare Mahjong. This can be achieved through:
Jokers are powerful - use them to complete difficult sets. Save them for crucial combinations rather than easy fills.
Track which bonus tiles have appeared. If you have 2-3 flowers/seasons, consider building your hand to capitalize on completing the set.
With limited Chow calling, focus on building Pongs. This is easier with jokers and scores more tai.
Taiwanese Mahjong moves quickly. Be ready to pivot your strategy based on jokers and flowers you draw.
The most standardized and strategically complex variant, featuring the riichi declaration system and defensive play
Japanese Mahjong, commonly called Riichi Mahjong, is the tournament standard in Japan and increasingly worldwide. It features highly standardized rules, complex scoring, and deep strategic elements including defensive play. The signature "riichi" declaration adds a layer of risk and reward not found in other variants.
The absence of bonus tiles makes the game more predictable and allows for deeper strategic calculation.
The defining mechanic of Japanese Mahjong:
Must have at least one yaku to win - no exceptions:
Dora indicators add scoring but are NOT yaku:
A unique defensive mechanism preventing certain wins:
Opening your hand reduces value significantly:
Japanese scoring is the most complex, using a two-component system:
Accumulated through yaku and dora. Each han roughly doubles the score.
Base score determined by hand composition (closed vs. open, sets vs. sequences, type of wait, etc.)
Calculated from han and fu using a standardized table. Ranges from 1,000 to 48,000 points (limit hands).
Maximum scoring hands worth 32,000-48,000 points:
A major element not emphasized in other variants:
Optimizing your hand to reach tenpai quickly:
Information gathering is crucial:
Don't always riichi immediately. Consider: your lead, hand value without riichi, dangerous tiles in your wait, and table position.
Dora are valuable but not yaku. Having multiple dora doesn't matter if you can't complete a yaku-qualifying hand.
Keep hands concealed unless calling immediately wins or creates a significantly better hand. Concealed hands score much higher.
Track your position. Sometimes a small win to avoid 4th place is better than risking everything for a big hand.
