You play the casino’s dealer program in SYSTEM 21, a blackjack roguelike that launches on Steam on 2 December 2026.
System Forge Studio is publishing the game itself, and its Steam page confirms the date. The free demo covers the first two campaign cycles and was out during October’s Steam Next Fest, so you can test the card queue before the full game launches.
The upcoming cards appear in a visible draw queue before they’re dealt. You can use DELETE to burn the next card or INVERT to swap the top two. You can also peek at the dealer’s hole card once per round, though that costs heat. Every intervention raises global suspicion, and at 100%, SYS_ADMIN traces the signal and your run ends.
Your targets are six types of patron: Tourists, Regulars, Drunks, By-the-Book, Card Counters, and Whales. Each has a wallet, a hype meter and different betting behaviour, and they disconnect if you fleece them too fast.
The campaign runs seven cycles, with quotas from $400 to $5,600. One persistent shoe grows from 4 decks to 8. Between cycles, you spend a slice of your winning profit on one of twelve plugins in the Compiler shop. Winning the campaign unlocks a Hard protocol with deal latency, where hesitating makes suspicion climb, and eleven Anomaly Challenges run from Easy to Insane.
The game is single-player, and the chips are simulated. The press kit says there’s no real-money wagering, and no loot boxes or microtransactions tied to gambling mechanics. The game is fully playable on the keyboard, with rebindable controls, and it supports nine languages on Steam. The press kit describes the look as strict Bauhaus.
Since the demo, the studio says it has worked through player feedback, fixing bugs and changing balance. It also says the full game adds dark mode, controller support, and better animations and sound. The Steam page’s description mentions neither dark mode nor controller support.
The studio hasn’t announced a price, and the press kit lists it as TBA.
The blackjack roguelike isn’t new territory. RogueJack: Roguelike Blackjack is already on Steam and pitches monsters and endless dungeons in “a game of 21.” Possessed Kingdom, a turn-based roguelike deckbuilder with route-drawn battles, launches on Steam on 3 December, a day after SYSTEM 21.
