Big Two

How to play

1. How to start a game of Big Two: The page opens on the setup screen. The House rules card has four rows, each with a switch: suit order (♦ lowest / ♣ lowest), 2s in straights (allowed / banned), flush comparison (suit first / rank first) and first lead (lowest card / last winner). Flip one and that row rewrites itself. Pick a computer level (Beginner / Standard) and tap Deal me in. All 52 cards are dealt one by one; tap anywhere to skip the deal.
2. How to play cards and why a play is refused: Tap a card to select it — it lifts and gets a violet outline, and the readout row names the hand you have formed. When a play cannot go, the Play button greys out and the status line says why: "The first play must include ♦3", "Play 5 cards — you picked 4", "These cards do not form a hand", "Pair 9 does not beat Pair K". Tap Pass when you cannot or will not beat the table; you cannot pass while leading. Hint only selects a legal play for you — it never plays it.
3. What clearing the table and taking the lead mean: After a play, the other three players either beat it or pass. Three passes in a row clear the table: the cards sweep back to whoever played last, and that player takes the lead with any single, pair, triple or five-card hand. Lead, last-card and whose-turn markers stay on the seats, so you can read the table even if you missed the animation.
4. How Big Two is scored: The first player to go out wins. Every loser pays per card left: 1 point each for 1–9 cards, 2 each for 10–12, 3 each for all 13; the winner collects everything, so the four scores always sum to zero. During play the readout shows "13 left · ending now −39" and updates the moment you play. Every deal has a code such as B02L1739204 — Copy deal link in the menu lets a friend play the exact same cards.

Rules & variants

Big Two basics: four players, one 52-card deck without jokers, 13 cards each and no kitty. The goal is to be the first to get rid of all your cards. Play moves in a fixed order — you, then the next player, the player across, and the previous player. The leader plays any legal hand; each following player must play the same number of cards and beat it, or pass. Passing does not lock you out of the trick. When three players pass in a row the table clears and the last player to play leads again. The round ends the instant anyone goes out.

Card ranking in Big Two: 3 is the lowest rank and 2 is the highest — 3 4 5 6 7 8 9 10 J Q K A 2, which is where the name comes from. Equal ranks are separated by suit, by default ♦ diamonds < ♣ clubs < ♥ hearts < ♠ spades, so the 3 of diamonds is the lowest card in the deck and the 2 of spades the highest. Some tables rank clubs lowest instead (♣ < ♦ < ♥ < ♠); the suit order switch handles that, and the lowest card becomes the 3 of clubs.

Big Two hands: singles, pairs, triples and five-card hands. Five-card hands rank, from low to high: straight < flush < full house < four of a kind (plus any fifth card) < straight flush. Four of a kind cannot be played on its own — it needs a fifth card. There are no bombs in Big Two: hands of different sizes never beat each other, so a straight flush only beats other five-card hands, never a single or a pair.

Comparing hands: singles compare rank first, then suit. Pairs and triples compare their highest card. Straights and straight flushes compare their top card (10-J-Q-K-A is the highest ordinary straight). A full house compares only its triple, four of a kind only its quad. Flushes compare suit first and then ranks from the top down by default; switch flush comparison to rank to compare ranks first and use suit only for a tie. Between different five-card classes the higher class always wins.

Can a straight contain a 2? Tables disagree more on this than anything else. By default A-2-3-4-5 and 2-3-4-5-6 count as straights here — and because they hold a 2 they outrank 10-J-Q-K-A, with A-2-3-4-5 the highest straight of all — while wrap-arounds through K-A-2 (J-Q-K-A-2, Q-K-A-2-3, K-A-2-3-4) never do. Set 2s in straights to Banned and A2345 and 23456 stop counting too — select them and the status line says "House rule: no 2 in straights".

Who leads first: by default the holder of the 3 of diamonds (3 of clubs when clubs are lowest) leads, and that first play must include the card — as a single, or inside a pair, triple or five-card hand. The alternative is that last round's winner leads with anything from the second round on; the first round still goes to the lowest card. Both are on the first-lead switch.

Big Two scoring: the winner collects every point the losers pay, so the four scores always sum to zero. This version uses tiered rates: 1 point per card for 1–9 cards left, 2 per card for 10–12, 3 per card for all 13. Nine cards cost 9 but ten cost 20, and an untouched hand costs 39 — that jump is why shedding cards early matters. The settlement card lists every loser's cards left, rate and penalty, and the winner's total.

Big Two versus President and other climbing games: President (Scum) lets you play any number of matching cards and ranks finishing positions; Big Two fixes hand sizes at 1, 2, 3 or 5, ranks suits as well as ranks, and scores by cards left. Big Two is also known as Big 2, Deuces, Dai Di and Pusoy Dos (which differs in some local rules). Players coming from other climbing games most often forget two things: different hand sizes never beat each other, and suits matter.

How many players and how long: Big Two is a four-player game. Here you play alone against three computer players, so you can start or stop any time. A round usually takes three to six minutes, and the menu has a fast animation speed. Your round is saved in this browser as you play: close the page, come back, and the same table is waiting — who leads, what is on the table and whose turn it is.

Big Two strategy: count plays, not cards — split your 13 cards into as few hands as possible and keep straights and full houses together rather than breaking them into singles. Save 2s and aces for winning back the lead instead of spending them on low singles early. Watch every opponent's card count; when someone is down to one card, stop leading singles and switch to pairs or five-card hands. Around ten cards left, shed fast — dropping below ten halves your rate. And pass freely when you cannot beat the table cheaply.

Common beginner mistakes: trying to beat a single with a pair (sizes must match — there are no bombs); playing four of a kind without a fifth card; forgetting that suits break ties, so the 2 of spades is the top card; and treating J-Q-K-A-2 as a straight — wrap-arounds never count here, and whether A2345 and 23456 count depends on the house-rule switch.
