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. Inspect remaining ranks and next-draw odds, then 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 a cut of each winning cycle in the Compiler.

Looks like a terminal.
Plays like a heist.

The Shoe Is a Visible Queue

See what's left, what returns on the reshuffle, and what's gone for good. Deep Scan reads the upcoming cards. You know the hand before you deal it.

DELETE Burns. INVERT Swaps.

During the dealer draw, burn queue [0] or swap it with [1]. Heat scales with the audit band. At 100% suspicion, SYS_ADMIN ends the run.

Six Patrons, Six Problems

Tourists, Regulars, Drunks, By-the-Book, Card Counters, and Whales. Each has a wallet, a hype meter, and unique betting AI. Pairings form table mixes that change how the floor bets and tilts.

Keep Them Seated. Then Take Their Wallets.

Hype is engagement. Blackjack spikes it. Losses drain it. At 100 they go HYPED. Starve it and they disconnect. Let them win enough to stay, then take the wallet.

Their 21 Keeps the Seat.

Every terminal pays out at once. A patron blackjack is the cost of keeping them seated. A dealer 21 is the extract.
