Blackjack where you cheat the deck, not the rules.

01

Read the queue

The shoe is a sequential buffer. You see the next card by default; Deep Scan reads up to five. Plan the hand before anyone is dealt.

02

Rewrite the draw

DELETE burns the next card. INVERT swaps the top two. Every exploit raises suspicion. Hit 100% and SYS_ADMIN traces the signal.

03

Extract and evade

Hit the cycle quota before the floor empties or drawdown tanks. Keep patrons hyped. Spend 10% of a winning cycle in the Compiler.

Looks like a terminal.
Plays like a heist.

The Shoe Is a Visible Queue

Upcoming cards sit in an open sequential buffer, newest at the top. Base visibility is one card. Deep Scan plugin adds depth. You read the shoe, then you deal it.

DELETE Burns. INVERT Swaps.

03 // THE FLOOR

Six Patrons, Six Problems

Tourists, Regulars, Drunks, By-the-Book, Card Counters, and Whales. Each has a different wallet, a hype meter, and unique behavior. Let them win enough to stay seated. Extract as much as possible before they disconnect. An empty floor below quota is a loss.
