Pure One-Suit Hand Building Tutorial

A pure one-suit hand is a classic goal in mahjong. In this traditional Chinese folk social entertainment game, a hand made entirely from one suit plus honors scores well and feels rewarding. Building one takes planning and patience. This tutorial walks you through every step, from the opening deal to the final winning tile.

Tile Knowledge

A pure one-suit hand uses tiles from only one suit.

Your three suit choices:
- Bamboo (Tiao): Green tiles with bamboo stick designs. Numbers 1 to 9.
- Characters (Wan): Red tiles with Chinese character markings. Numbers 1 to 9.
- Dots (Tong): Blue or green tiles with circular dot designs. Numbers 1 to 9.

Allowed honors in a pure one-suit hand:
- All four winds (East, South, West, North).
- All three dragons (Red, Green, White).

You can mix honor tiles with your chosen suit. The hand remains pure as long as you use only one number suit.

Tile count for a pure one-suit hand:
- 36 tiles in each suit (four copies of numbers 1 through 9).
- 28 honor tiles (16 winds plus 12 dragons).
- Total available: 36 tiles of your suit plus 28 honor tiles.

You do not need honors. Some players prefer a pure suit hand without any honors. This is harder but scores even more.

Game Steps

Follow these steps to build a pure one-suit hand.

Step 1 — Check your opening hand.
Count tiles in each suit. If you have six or more tiles in one suit, consider a pure one-suit hand. If you have seven or more, start building immediately. Fewer than six tiles in any one suit makes a pure hand difficult.

Step 2 — Choose your suit.
Pick the suit with the most tiles. If two suits have equal count, choose the one with more connected tiles. Connected tiles are numbers close together, like 4-5-6, not 1-8-9.

Step 3 — Discard other suits.
Remove all tiles from the other two suits first. These tiles do not help your goal. Discard them quickly to show your intent. Early discards signal your direction to other players.

Step 4 — Check your honor tiles.
Honor tiles can stay in your hand. They are part of a pure one-suit hand. Keep honor tiles that form pairs or are valuable. Discard single honor tiles if you have too many.

Step 5 — Build sequences in your suit.
Focus on making sequences within your chosen suit. Sequences are three consecutive numbers like 2-3-4 or 6-7-8. They are easier to complete than triplets.

Step 6 — Watch for the pair.
Your hand needs a pair to win. The pair can be any two identical tiles from your suit or honor tiles. Keep a pair safe. Do not break it unless you have a second pair.

Step 7 — Stay on track.
Once you discard the second suit, do not go back. Changing suits mid-game wastes turns. Commit to your pure one-suit goal and keep drawing.

Valid Hand Combinations

Pure one-suit hands follow the same structure as regular hands: four groups plus one pair.

Valid group types:
- Sequences within your suit: Three consecutive numbers of your chosen suit.
- Triplets within your suit: Three identical numbers of your suit.
- Honor triplets: Three identical wind or dragon tiles.
- Kong: Four identical tiles.

Example pure one-suit hand (Bamboo):
- 2-3-4 Bamboo (sequence)
- 5-6-7 Bamboo (sequence)
- 8-8-8 Bamboo (triplet)
- East-East-East (honor triplet)
- 4-4 Bamboo (pair)

This hand uses only Bamboo tiles and honor tiles. It qualifies as a pure one-suit hand.

Common pure one-suit patterns:
- All sequences: Easier to build. Five sequences including the pair.
- Mixed sequences and triplets: Medium difficulty. Two sequences and two triplets.
- All triplets: Hardest. Four triplets plus a pair. Rare in family play.
- Honor heavy: Many honor tiles plus a few suit sequences.

What to avoid:
Do not mix two suits. Even one tile from a second suit breaks the pure one-suit condition. Check your hand before declaring.

Scoring

Pure one-suit hands score higher than mixed hands in family mahjong.

Base scoring:
- Pure one-suit hand (with honors): 6 points.
- Pure one-suit hand (no honors, all from one suit): 8 to 10 points.
- All sequences inside the pure hand: +2 points.
- All triplets inside the pure hand: +4 points.

Bonus elements:
- Self-drawn winning tile: +2 points.
- No calls on other players (self-drawn entirely): +2 points.
- Dragon triplet: +1 point per triplet.
- Seat Wind triplet: +1 point.

Comparison to mixed hands:
- Average mixed hand: 2 to 4 points.
- Average pure one-suit hand: 6 to 10 points.
- Pure one-suit hands score about double a mixed hand.

The higher score makes the challenge worthwhile. Even if you only win once in a session, a pure one-suit hand can put you ahead.

Game Skills

Skill 1 — Start with Bamboo or Dots.
Bamboo and Dots are easier to read for beginners. Their number markings are more visible. Characters require recognizing Chinese script, which can be slower.

Skill 2 — Keep middle numbers.
Numbers 3 through 7 are the most flexible in your chosen suit. They can form sequences in both directions. Edge numbers like 1 and 9 only form one direction.

Skill 3 — Use honors as fillers.
If your suit tiles are not connecting well, keep honor tiles. Honors break up the hand and give you triplet opportunities. They also provide safe discards if needed.

Skill 4 — Call for tiles wisely.
Calling (claiming an opponent discard) shows your hand direction. If you call a tile from your pure suit, everyone knows your plan. Sometimes it is better to draw your own tiles and keep opponents guessing.

Skill 5 — Know when to give up.
If after ten draws your pure suit has not improved, consider changing direction. A pure one-suit hand requires luck and patience. If the tiles are not coming, switch to a mixed hand. This is better than losing the round.

Summary

Building a pure one-suit hand is a rewarding challenge in mahjong. Check your opening hand for six or more tiles in one suit. Discard other suits quickly. Build sequences and keep honors as fillers. Score double or more compared to mixed hands. This traditional Chinese folk social entertainment game offers many paths to victory. The pure one-suit hand is one of the most satisfying. Practice with Bamboo or Dots first. As you gain confidence, try Characters. Pure one-suit hands will elevate your family game nights.
