Rules of Chan (Chắn)#

Chan (also spelled Chắn) is a traditional Vietnamese card game derived from To Tom. It is a sophisticated draw-and-meld game played with 100 cards and 4 players, requiring strategic thinking, memory, and careful observation of opponents' discards. The goal is to form combinations and achieve Ù (winning hand) or have the lowest score.

1. The Cards#

The deck consists of 100 cards divided into three suits plus special cards:

The Three Suits (Hàng)#

Special Cards#

• Chi Chi (四支): 4 copies - These are wild cards that can substitute for certain combinations

Each number from 2 to 9 has specific Vietnamese names:

• Nhị (2), Tam (3), Tứ (4), Ngũ (5), Lục (6), Thất (7), Bát (8), Cửu (9)

Card Reading Example#

A card marked "Tam Vạn" means: the number 3 (Tam) in the Myriad suit (Vàn). There are 4 identical copies of this card in the deck.

2. Basic Setup#

• Players: Exactly 4 players (traditionally played sitting in a square)
• Dealing: Each player receives 19 cards
• The Nọc: The remaining cards (24 cards) are placed face-down in the center as the draw pile
• Discard Pile: Cards discarded by players form a visible pile next to the Nọc

Dealing Procedure#

1. Shuffle the deck thoroughly
2. One player (the dealer) distributes 19 cards to each player, one at a time
3. Players arrange their cards privately (usually sorted by suit and number)
4. The player to the dealer's right takes the first turn

3. Gameplay Loop#

Chan focuses on pair-building rather than long sequence runs. Players aim to form two types of combinations:

Combination Types#

Turn Structure#

On your turn, you may perform ONE of these actions:

1. Draw (Bốc): Take the top card from the Nọc (draw pile)
2. Eat (Ăn): Take the card just discarded by the previous player to form a Chắn or Cạ
3. Discard (Đánh): After drawing or eating, you must discard one card face-up

Important Rules#

• You can only "Eat" if the discarded card immediately forms a valid Chắn or Cạ with cards in your hand
• If you draw a card that completes a Chắn or Cạ, you may immediately declare it
• The discard pile is visible to all players - use this information to track cards
• If the Nọc runs out before anyone wins, the game is a draw

4. Winning (Ù)#

You win (called Ù, pronounced "oo") when your 19 cards plus one card (drawn or eaten) form a complete hand of:

• Minimum 6 Chắn (pairs of identical cards)
• The remaining cards form valid Cạ (cross-pairs)
• Zero unmatched "orphan" cards

Winning Declaration#

When you believe you have a winning hand:

1. Announce "Ù!" clearly
2. Lay down all cards face-up
3. Other players verify your combinations
4. If valid, you win the calculated points (Cước)

5. Scoring (Cước)#

Victory points are calculated based on the complexity and rarity of the winning hand. Higher Cước = more points/money won.

Basic Cước (1 Point)#

Special Cước (Higher Points)#

Rare Cước (Maximum Points)#

Stacking Rules#

Some Cước can combine for higher total points:

• Example: Thiên Ù + Tôm = 3 + 2 = 5 points
• Local house rules may vary on stacking

6. Strategy Tips#

For Beginners#

1. Sort your hand immediately - Organize by suit, then by number to see potential pairs
2. Track discards - Watch what opponents discard to know what cards are "dead"
3. Prioritize Chắn over Cạ - You need at least 6 Chắn to win
4. Don't chase rare combinations - A simple Xuông win is better than waiting for Tôm

Intermediate Strategy#

1. Defensive discarding - Avoid discarding cards that might help the next player
2. Memory training - Track which cards have been played to calculate odds
3. Read opponents - Notice which suits they're collecting or avoiding
4. Flexible hands - Keep multiple paths to completion rather than one rigid plan

Advanced Concepts#

1. Card counting - Know exactly how many copies of key cards remain
2. Tempo management - Balance speed of completion vs. quality of Cước
3. Table position - Your seat relative to the dealer affects strategy
4. Psychological elements - Control your reactions when drawing key cards
