How to Count Fan Points Step by Step
Scoring in mahjong can feel confusing at first. But it follows clear rules. Fan points are the building blocks of mahjong scoring. Each fan represents a multiplier. More fan means a higher score. This guide teaches you how to count fan points step by step. You will learn to score any hand with confidence.
Tile Knowledge for Scoring
Before counting fan, know your tiles. Mahjong has three suits: Bamboo, Characters, and Dots. Each suit has tiles numbered 1 through 9. There are four copies of each tile. Honor tiles include four Winds and three Dragons. Flower tiles add bonus points in some variations.
Fan points come from patterns in your hand. A pattern is a special arrangement of tiles. Each pattern has a fixed fan value. You add up all the fan values from your patterns to get your total score.
Some patterns are simple. Some are complex. You can combine multiple patterns in one hand. The total fan determines how much the winning player receives.
Step One: Check for Basic Fan Patterns
Start with the simplest patterns. These are easy to spot and add one fan each.
A "fully concealed hand" gives one fan. This means you won with a closed hand. You never called a pung, chow, or kong. You drew the winning tile yourself from the wall.
A "self-draw" win gives one fan. You drew the winning tile yourself. This is also called "tsumo." Even if your hand is open, drawing your own winning tile earns one fan.
A "single wait" gives one fan. Your hand waits on only one specific tile. For example, you hold 3 and 5 and wait on 4. Or you hold a pair and one of another tile, waiting for the third.
A "no point hand" gives one fan. This is also called "pinfu." Your hand has no triples, no honor tiles, no terminals, and no bonus patterns. It is a clean hand of sequences and a matching pair.
A "terminal in each set" gives one fan if exactly three sets contain terminal tiles. A terminal is a 1 or 9 tile.
Step Two: Check for Honor Tile Patterns
Honor tiles add fan points to any hand.
A "dragon triple" gives one fan. You have three identical Dragon tiles. Red, Green, or White Dragon all count. A Dragon pair does not give fan.
A "seat Wind triple" gives one fan. The Wind matching your seat position. If you sit South and have three South Winds, that is one fan.
A "round Wind triple" gives one fan. The Wind matching the current round. East round means East Wind triples are worth one fan.
If the seat Wind and round Wind are the same, a triple of that Wind gives two fan. For example, East seat during East round with three East Winds.
Step Three: Check for Suit-Based Patterns
These patterns involve the numbered suits.
A "mixed triple sequence" gives two fan. You have the same number sequence in all three suits. For example, 1-2-3 Bamboo, 1-2-3 Characters, and 1-2-3 Dots.
A "pure straight" gives two fan. You have a 1-2-3-4-5-6-7-8-9 straight in one suit. This uses three sequences covering all nine numbers.
A "full flush" gives three fan. Your entire hand uses only one suit plus honor tiles. All Bamboo tiles with some Dragon or Wind triples. This is also called "honor and one suit."
A "half flush" gives two fan. Your hand uses one suit and honor tiles but the sequences within that suit are mixed with honors.
Step Four: Check for Terminal and Honor Patterns
These patterns involve the edge tiles and honors.
A "mixed outside hand" gives one fan. Every set in your hand contains at least one terminal or honor tile. No set is purely middle numbers.
A "pure outside hand" gives two fan. Every set contains a terminal tile. No honor tiles are used. All sets must include a 1 or a 9.
A "all terminals and honors" gives two fan. Your entire hand uses only 1s, 9s, Winds, and Dragons. No middle numbers at all.
A "all honors" gives four fan. Your hand uses only Wind and Dragon tiles. This is a very rare pattern.
Step Five: Check for Special Patterns
Some patterns are rare and score many fan.
A "seven pairs" gives two fan. Your hand has seven different pairs. This pattern is only possible with a closed hand.
A "thirteen orphans" gives a limit hand score. This is the highest fan level. You collect one of each terminal and honor tile plus one duplicate. This pattern is very rare.
A "little three dragons" gives two fan. You have two Dragon triples and one Dragon pair. For example, three Red Dragons, three Green Dragons, and a pair of White Dragons.
A "big three dragons" gives a limit hand score. You have three Dragon triples. Red, Green, and White all in triples.
Step Six: Add Up All Fan Points
Count every applicable pattern from your hand. Add them together. Some patterns combine. Some do not. Check which patterns are compatible.
Here is an example. You win with a closed hand (1 fan). You drew the winning tile yourself (1 fan). You have a Dragon triple (1 fan). You have a mixed triple sequence (2 fan). Total is 5 fan.
Another example. You win with an open hand (no closed bonus). You have a seat Wind triple (1 fan). You have a half flush (2 fan). Total is 3 fan.
Step Seven: Convert Fan to Score
Each rule set has its own scoring table. A common system is base points times two to the power of fan. Base points are usually 20 or 30 points.
A one fan hand: 20 base times 2 equals 40 points. A two fan hand: 20 base times 4 equals 80 points. A three fan hand: 20 base times 8 equals 160 points. A four fan hand: 20 base times 16 equals 320 points. A five fan hand: 20 base times 32 equals 640 points.
In family games, you can use a simpler system. Each fan doubles the base score. Use a scoring chart for quick reference.
Summary
Counting fan points follows a clear order. Start with basic patterns. Check honor tile patterns. Look for suit-based patterns. Check terminal and honor patterns. Look for rare special patterns. Add all compatible fan values. Convert to score using your house rules. Practice counting fan in your family games. It becomes easy with experience. Soon you will count fan as naturally as you build your hand.
