Blackjack — Live Croupier Table

American blackjack for the casino floor. A Game Master opens a physical table as the croupier and paces the game: bets open, cards dealt, reveal, next round. Up to four players bet into the same round against a single dealer hand. The house is the bank, so the croupier never risks a cent, and everything is decided server-side.

How it works

Start to finish

The croupier panel: open bets, deal, reveal, the auto toggle and dev bots 2 / 3
01 — The croupier

The croupier runs the table
- Opens bets, deals, reveals and starts the next round by hand, like a real pit dealer.
- Or flips the table to auto and lets timers pace the phases.
- Dev bots can fill the empty seats to exercise a full table solo.
A split in play: the seat fans into two hands and the plate tracks each hand's total as they play out in turn 3 / 3
02 — The rules

Full American rules, decided on the server
- Hit, stand, double and split: equal rank only, one split, double-after-split except on aces. Dealer stands on all 17s, blackjack pays 3:2.
- With an ace or a ten-value card up, the server checks the hole card before anyone risks double or split money. A dealer blackjack ends the round on the spot; player blackjacks push instead of losing.
- The six-deck shoe is reshuffled every round, so card counting is off the table.

Under the hood

What keeps it solid

Money

Bets are debited as they're placed; wins are created at settlement.
Every movement is logged.
KVP snapshots and an owed-money ledger turn a disconnect, a table close, a resource stop or a crash into a refund, at worst on next login.

Testing

The round is a pure Lua state machine with the deck injected from outside.
The test suite deals rigged shoes and replays whole rounds in a plain Lua interpreter, no game running.
A headless-Chrome harness drives the real page through deal, split, reveal and settle, each fix landed against a failing negative control first.

Seats and animation

Seat anchors are read off the table model's skeleton bones at runtime, the technique Rockstar's own casino script uses.
Official casino animations cover bet, hit and stand plus the win, lose, push and bust reactions.
Cards fly in from the shoe, the hole card flips in 3D, chips fly from the bet button to the spot; sounds are scoped to their round.

Anti-abuse

Bet limits with a hard 4× per-seat exposure cap, and action throttling.
A 20-second action window auto-stands absent players; an anti-AFK watchdog frees seats.
Single-exit close paths, so money leaves a table through exactly one route.
