Start
Each player is secretly dealt an Ace. Players win by obtaining cards that match the suit of their assigned Ace.
Your Turn
On your turn, either Draw or Trade.
- Draw: Take the top card of the draw pile in secret. Put it in your Bank face down or on your Trading Floor face up.
- Trade: Offer any number of cards from your Trading Floor for any number of cards from one other player's Trading Floor.
- If your trade is rejected, you're unable to send another offer to that player till your next turn. You can still send offers to other players, or draw instead.
Bank
Cards placed into your Bank are not revealed or moved until the end of the game.
Trading Floor
Cards placed on your Trading Floor can be traded later on. Once a card is there, it stays there until it is traded away. Cards you receive in a trade can go either in your Bank or back on your Trading Floor.
Forced Draw
If every active player trades consecutively, the next player must draw.
Winning
When the draw pile is empty, players count how many cards in their Bank and Trading Floor match the Secret Suit of their Ace. The player with the highest count wins. If two players have the same amount, the winner is determined by tiebreakers:
- Most Sister Suit cards(Cards that share the color of your Secret Suit)
- Most total cards
- Most face cards
- Highest total value (Face cards count as 10)
Bot Personalities
Bots are randomly assigned personalities before each game. On Easy Mode, you can see which personality each bot has. On Normal Mode, their personalities are hidden. On Hard Mode, one of the bots will be the "Hustler" personality, which plays more like a skilled human would.
BrokerTrades most of the time.
ProspectorDraws most of the time.
BankerUsually puts cards in their Bank.
ShopkeeperUsually puts cards on their Trading Floor.
BenefactorAccepts trades more often.
HagglerCounters trades more often.
MiserRejects trades more often.
GratefulThe more you trade with them, the more they will accept bad trades from you.
SpitefulRemembers who rejects their offers and is less willing to accept even good trades from them.
TricksterObscures their Secret Suit by playing erratically.
AuditorTracks which Suit each opponent wants, and denies them.
Hustler ADVANCEDOne bot on Hard Mode will have this personality. Plays more like a clever human than the other bots.
Secret SuitThe Ace you are dealt at the start of the game assigns your Secret Suit. When there's no cards left to draw, the player with the highest count of their own Secret Suit wins the game.

Assumed SuitYou can keep track of what you think an opponent's Secret Suit is. Click that opponent's Bank to choose a suspected suit; the marker is only a reminder for you and does not change the game. You cannot mark your own Secret Suit as an opponent's suit.

One Man's TrashEarly in the game, cards outside your Secret Suit and Sister Suit are basically trash, because you don't know who wants them. Once opponents reveal what they value through their trading habits, that same trash becomes useful fodder: cards you don't want, but somebody else does. Sometimes you should accept a trade you don't want to set up a trade you do.

GoodwillOne-sided deals will only get you so far. A fair deal now can make a player more willing to deal with you later. Goodwill mostly applies to the Spiteful and Grateful personalities, but also applies to playing against humans online.

Sending vs. Accepting a TradeSending an offer uses your turn if the trade is accepted. Accepting someone else's offer happens on their turn, so you still get to act on your own turn. That makes acceptance especially valuable.

- Prevented a completed game’s delayed end reveal from resurfacing after a new game starts.
Version 3.1

Version 3.0.1

- Updated the decorative table wordmarks to use Quarta's two-tailed Q.
- Changed the endgame stat label from “Suit cards” to “Secret Suit cards.”
