YOU ARE
THE HOUSE.

See every card before it hits the table. Then change it.

Run the casino backend. Rig outcomes. Stay under the radar. One wrong move and SYS_ADMIN wipes you.

Windows & macOS · Demo available

Blackjack where you cheat the deck, not the rules.

01

Read the queue

The shoe is an open array. You see what's coming. Plan the hand before a single card lands.

02

Break the deck

Delete the next card. Swap the top two. Every exploit spikes suspicion, push too hard and you're reset.

03

Run the floor

Hit quota. Manage heat. Upgrade between runs. Whales, counters, tourists, each one a different puzzle.

Looks like a terminal. Plays like a heist.
