We broke Hold 'em.
Costanza is Texas Hold'em, flipped completely upside down.
The worst hand at showdown wins.
Simple to learn.
Painful to master.
If you've played Hold'em, you already know 95% of Costanza's rules.
Hole Cards
Each player receives two private cards face-down. Already rooting for low cards? You're getting it.
Preflop Betting
Blinds are posted. Betting begins. You fold, call, or raise. Same as always. Except now 73os is lookin' kinda spicey.
The Flop, Turn & River
Five community cards hit the board in standard fashion. Betting continues each round.
Showdown - Worst Wins
Make the best five-card combination from any combo of your two hole cards and the board - but evaluated in reverse. The weakest hand claims the pot.

You've got 7♣ 8♣. In Hold'em you're hoping for a 6. In Costanza you're hoping for anything low and ugly, the more disconnected the better. Same hand, completely different prayer. The board, the betting, the interface are all identical.
Every other rule is identical to Texas Hold'em. The hand rankings are just flipped. High card is #1. Straight flush is the kiss of death.
A few things worth knowing before you dig in.
None of this requires setup. It's just already there.
Your Opponent
He tilts, bluffs, panics when short-stacked, and has a different bet-sizing personality every session. He's not just a random number generator in a button down.
Each one changes a single rule. Everything from God mode to donut chips. Hit Free Upgrades before any game to flip them on.
These might work now, or not:

Hit a milestone and a badge appears. Some are obvious. Some are cryptic on purpose and we're not going to tell you what triggers them.
You're ready.
Go lose beautifully.
Three seconds in, you'll fold something good on instinct and immediately hate yourself. Welcome.
