Poker engine as an API
for operators.

API First
integration
Same Server-authoritative
engine
White Label cash +
tournaments

By exposing a proven engine as an API, the operator embeds cash and tournaments on the same server-authoritative core that's already live — shipping real poker into their product without taking on the engine-correctness risk that sinks most in-house attempts.

The Customer. An operator who already has a platform and an audience, and wants to embed real poker — cash games and tournaments — without building a game engine themselves. The requirement is to add poker to an existing product, not to rebuild the product around poker.

The Challenge. The hard, risky part of poker is the engine: correctness, side pots, all-in resolution, a defensible shuffle, server authority. An operator who tries to build that in-house takes on the exact risk River has already retired. An operator who buys a black-box skin gives up control of their product and their roadmap.

There's a third path. River can expose the same server-authoritative engine that runs in production as an API — the operator's front end calls in, River's server remains authoritative over every game decision and chip movement, and the operator owns the experience layer entirely.

The Solution. River exposes the same server-authoritative engine that runs in production as an API — white-label cash and tournaments embedded into the operator's existing platform, with River owning the game correctness and the operator owning the experience. B2B, API-first, same engine already in production.

Under the Hood.

Engine Surface
The production holdem.js and PLO engine, CSPRNG shuffle, side-pot and all-in resolution, and tournament system exposed via an API surface.
Authority Model
Operator's front end calls in; River's server remains authoritative over every game decision and chip movement. The client cannot influence game outcomes.
Audit & Ledger
Same audit-grade ledger behind it — every chip movement recorded with a reason code, queryable by the operator for their own reporting.
Integration Model
Integration Model
B2B, API-first. The operator integrates their existing front end against River's API. White-label — the operator's brand, River's engine.

Results. By exposing a proven engine as an API, the operator embeds cash and tournaments on the same server-authoritative core that's already live. River can deliver this integration — shipping real poker into the operator's product without the operator taking on the engine-correctness risk that sinks most in-house attempts.

"Same server-authoritative engine, exposed as an API — they own the product, we own the game."
