Pusoy Dos Rules
Everything you need to sit down at the table — how the cards rank, what you can play, and how to win. These match exactly how the game plays on JesterDosAI.
01 Objective
Be the first to empty your hand. Four players are each dealt 13 cards from a standard 52-card deck. As each player runs out of cards they lock into a finishing place — 1st, 2nd, 3rd, and 4th (the last player still holding cards).
02 Card ranking
Ranks, low to high — the 2 is the highest rank, the 3 the lowest:
Suits, low to high — suit only matters to break ties between equal ranks:
Put together, this makes the 2♦ the single highest card in the game.
03 The deal & opening
All 52 cards are dealt out — 13 to each of the four players. Whoever holds the 3 of clubs (3♣) leads the very first play, and that play must include the 3♣. You can lead it as a single, or fold it into a pair, triple, or five-card hand.
04 Turns, control & passing
Play passes around the table. On your turn you must either play a combination that beats the current pile, or pass. Passing sits you out until the pile resets.
When every other active player passes in a row, the last person to play wins control and leads a fresh pile with any combination they like. (If that player just went out, control passes to the next active seat.) You cannot pass when you have control — you must lead.
05 What you can play
Every pile is one of the shapes below. You can only answer a pile with the same shape and the same number of cards — a pair only beats a pair, a straight only a straight:
| Combination | Cards | Notes |
|---|---|---|
| Single | 1 | Compared by rank, then suit |
| Pair | 2 | Two of the same rank; higher rank wins, suit breaks ties |
| Triple | 3 | Three of the same rank |
| Five-card hand | 5 | Straight, flush, full house, four-of-a-kind, or straight flush |
There are no four-card plays.
06 Five-card hand ranking
A stronger category always beats a weaker one, regardless of the cards involved:
Straight < Flush < Full House < Four of a Kind < Straight Flush
So any flush beats any straight, any full house beats any flush, and so on. Within the same category, the higher-valued hand wins.
07 Straights
Valid straights run from A-2-3-4-5 (lowest) and 2-3-4-5-6, then 3-4-5-6-7 all the way up to 10-J-Q-K-A (highest). Wrap-arounds such as J-Q-K-A-2 are not legal.
Note that the two low straights containing a 2 or Ace still rank below 3-4-5-6-7 — the 2's high rank doesn't inflate a low straight's strength.
08 Beating the pile
Match the count and type, then win on value: higher rank (suit breaks exact ties) for singles, pairs, and triples; for five-card hands, a higher category wins outright, otherwise the higher-valued hand of the same category. You can never switch types mid-pile.
09 Winning
The first player to shed all 13 cards takes 1st place; play continues for the remaining seats until only one player is left holding cards (4th). Going out on the 2♦ — the highest card in the game — is the ultimate finish, and it's exactly why tournament scoring awards a bonus point for a win clinched on the 2 of diamonds.
