In Costanza Poker, everything is the opposite.
The worst hand in regular poker is the best hand here.

High Card — The ultimate winner. Nothing fits together.
One Pair — Second best. Just two matching cards.
Two Pair
Three of a Kind
Straight — A-2-3-4-5 is the best straight; T-J-Q-K-A is the worst.
Flush
Full House
Four of a Kind
Straight Flush — Almost always fatal. A-2-3-4-5 suited is the one version you can live with.
Royal Flush — T-J-Q-K-A suited. You made it. You should be proud. Now please, just go low.

Heads-up (2 players) Texas Hold'em rules — but rankings are inverted.
Hold'em mode: Each player gets 2 hole cards. Use any combination of hole cards and board to make your best 5-card hand.
Omaha mode: Each player gets 4 hole cards. You must use exactly 2 of your hole cards and exactly 3 board cards.
Five community cards are dealt (Flop, Turn, River).
Best 5-card hand wins — but “best” means closest to High Card.
Blinds start at 10 / 20. Starting stacks are 2,000.
Match plays until one player runs out of chips.

Within the same hand type, lower card values win.
High card / Flush: lowest top card wins — 7-high beats Q-high, 2-high beats Ace-high.
Pairs / Trips / Quads: lowest rank wins — pair of 2s beats pair of Aces.
Straights: Ace plays low (as 1) — A-2-3-4-5 is the best straight because it's the lowest. T-J-Q-K-A is the worst.
Outside of straights, Ace is always high (14) — so it's the worst card to have in your high-card hand or flush.

Avoid connecting cards — straights and flushes hurt you.
Mixed suits, non-sequential ranks are your best friends.
Suited connectors (7♠8♠) are trash — fold them.
Offsuit, disconnected cards (2♣ 9♦) are gold.
The Hand panel bottom-right shows your current hand rank and percentile in real time.
