A solo card-driven game system

One deck.
Endless worlds.

Poker Run Engine turns a standard 52-card deck into a full solo campaign. Draw your hand, read what it tells you, and push deeper before the run turns against you — across a growing shelf of standalone genre settings, from cosmic horror to cyberpunk data-heists.

Why this system

Why Poker Run Engine?

One resolution system. One deck. Genre-agnostic core. Built for short, tense solo expeditions.

Standard deck only

No custom cards or dice required. A normal 52-card deck is the entire resolution engine.

No dice

Every check is a poker hand. Pattern recognition, not arithmetic.

Genre-agnostic core

The same engine powers sci-fi salvage, folk horror, trench warfare, and cyberpunk heists.

Easy to learn

Draw five, discard what you don't want, evaluate the hand. That's the whole resolution system.

Designed for solo play

Short expeditions (10–25 minutes), clear pressure curve, and a real final confrontation.

Free SRD

The full core system is open. Build and publish your own overlays under the PRECL.

The core loop

Every hand is a decision

Every overlay runs on the same resolution system — no two runs read the same way, because no two hands do.

Try a check yourself →

Draw

Build your hand from the deck. What you're dealt sets the shape of the run before you make a single choice.

Push

Advance into the next zone. Every overlay reskins this differently — a wreck, a woods, a city block — same pressure underneath.

Spend

Burn resources to improve a bad hand or bank a good one. What you're protecting always costs something.

Confront

Face what the run's been building toward. Pair or better and you've got a shot — high card alone won't save you.

The catalog

Standalone overlays, one shared system

Each overlay is a complete, runnable game on its own — no SRD required. Buy one, grab a deck, play.

For creators

Build your own game.

The System Reference Document holds the full core engine — the resolution system, the resource framework, and the design patterns every overlay above is built from. It's not a requirement to play; it's an invitation to build.
