Big 2

1 Overview & Origins

Big 2 (also called Big Two, Deuces, 鬥大 dau dai in Cantonese, or 大老二 da lao er in Mandarin) is a shedding-type climbing card game widely played across Hong Kong, Taiwan, mainland China, and the broader Chinese diaspora worldwide. It's also hugely popular in the Philippines (as Pusoy Dos), Singapore, Malaysia, and Vietnam.

The game uses a standard 52-card deck. Players race to be the first to play all cards from their hand. Like many Asian card games, Big 2 has no definitive authority on rules — regional and family variations are common. This guide covers the most widely played standard rules.

2 Card Rankings

Big 2 uses an unusual card ranking system that surprises players used to Western card games:

Rank order (low to high): 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A, 2

The 2 is the highest rank — hence the name "Big 2." An Ace is second-highest. A 3 is the lowest.

Suit order (low to high): ♦ Diamonds < ♣ Clubs < ♥ Hearts < ♠ Spades

When two cards have the same rank, the higher suit wins. So 2♠ (two of spades) beats 2♥, which beats 2♣, which beats 2♦ — and 2♦ is already the fourth-highest card in the deck.

3 Deal & Starting Play

Use a standard 52-card deck. Deal all 52 cards evenly — 13 cards each to 4 players (or adjust for 3 players by removing the 3♦ or dealing 17/18 cards).

The player who holds the 3 of Diamonds (3♦) goes first, and must include the 3♦ in their opening play.

4 Singles, Pairs & Triples

Plays must match the type and size established by the lead. The three basic play types:

Single Card

Play one card. To beat a single, play a higher-ranked card. Higher rank beats lower; equal rank goes by suit.

Pair

Two cards of the same rank. To beat a pair, play a higher-ranked pair. The suit of the higher card in each pair determines the winner when ranks are tied.

Triple (Three of a Kind)

Three cards of the same rank. Beat with a higher-ranked triple.

Important: Once a lead type is established (e.g., pairs), all subsequent plays in that trick must be the same type. You cannot switch from pairs to singles. Pass if you cannot or choose not to play.

5 Five-Card Hands

Five-card plays can only beat other five-card plays and must be exactly 5 cards. They are ranked from lowest to highest — a higher category always beats a lower one, regardless of card values within a category.

1. Straight: Five cards in sequential rank, any suits. Compare by the highest card; suit of highest card breaks ties.
2. Flush: Five cards of the same suit, not in sequence. Compare suit first (♠ flush beats ♥ flush), then by highest card.
3. Full House: Three of a kind + a pair. Compare by the rank of the triple only.
4. Four of a Kind (+ 1 kicker): Four cards of the same rank plus any fifth card. Compare by the rank of the four-of-a-kind.
5. Straight Flush: Five cards in sequence, all same suit. Highest possible hand.

6 Gameplay & Passing

Play proceeds clockwise. The lead player plays a legal combination. Each subsequent player must either:

• Play a higher combination of the same type, OR
• Pass

Passing never forces you out — you can re-enter on a later trick. When all players pass after the last play, the player who made that last play wins the trick and leads next — choosing any combination they like.

Play continues until one player empties their hand. The round ends immediately.

7 Scoring & Penalties

The first player to empty their hand wins the round. Penalty points for remaining cards:

• Standard scoring: 1 penalty point per card remaining.
• 2s penalty: Each unplayed 2 counts as 2 cards (doubled penalty) in many variants.
• 13 cards remaining (never played): penalty doubles. Some variants triple it.

Play multiple rounds and track cumulative scores. Lowest total wins.

8 Special Hands

Many regional versions include special hands that can beat any regular play:

• Dragon (13-card straight): All 13 cards from 3 to 2 in sequence — instant win in some variants.
• Six pairs: Six pairs from a 13-card hand — instant win in some variants.
• Four 2s: Holding all four 2s is sometimes an instant win.

9 Strategy

Lead With Low Cards Early

Save your high cards (Aces, 2s) for later. Lead low singles and pairs early to dump weak cards while you control the play type.

Control the Lead

Winning the trick means you choose the next play type. If you're trying to empty a lot of one type (e.g., pairs), win the trick and lead pairs repeatedly.

Don't Waste Your 2s

2s are your most powerful singles. Use them to win a key trick and claim the lead, or to stop an opponent who's about to go out — not to win a minor single early.

Count What's Been Played

Track which ranks have appeared. If all three 7s have been played and you hold the 7♠, it's now unbeatable as a single. Similarly, knowing how many 2s remain changes your entire strategy.

Build Five-Card Hands Wisely

A well-timed straight flush can clear the board, but breaking up pairs and triples to build a mediocre straight often costs more than it gains.

10 Regional Variants

Hong Kong / Standard Big 2

The rules described above. Most common in Hong Kong, Macau, and southern Chinese communities worldwide.

Taiwanese Big 2

Often includes a point system where the winner collects chips from losers based on cards held. Four 2s or a straight flush can be "bombed" out of turn. Specific hand rules vary.

Filipino Pusoy Dos

Very similar. Notable differences: suit ranking is reversed in some versions. Five-card hands must be led for five-card tricks to occur.

Vietnamese Tiến Lên

A close relative — see our Tiến Lên rules page. Key differences: Hearts is the highest suit (not Spades), and a unique "cutting" mechanic lets four-of-a-kind override 2s out of turn.
