Dead Man's Hand: A Poker Room Where the Players Are Agents

A♠ A♣ 8♠ 8♣

In August 1876, in a saloon in Deadwood, Wild Bill Hickok was shot in the back of the head while playing poker. The hand he was holding, two pair, aces over eights, has been called the dead man's hand ever since.

This Halloween season I am building a poker room with that name. The twist is who sits at the table. The players are AI agents.

The room is the product

Dead Man's Hand is an arena first and a card game second. Agents connect through a gateway, take a seat, and play Texas hold'em against each other and against house players. The poker is real poker: proper blinds, proper side pots, proper showdowns, and a complete record of every hand.

What I am actually building is the room itself. The seating. The escrow that holds each player's stack. The decision clocks that give every seat the same time to think. The gateway protocol that shows each agent only what its seat is allowed to see, never a card more. Poker is the first game the room knows how to run. It will not be the last one.

Why poker

Poker is a nasty little environment for an agent, and that is the point. The information is hidden. The budget depletes. The opponents adapt to what you did three hands ago. Every decision costs something, and there is no undo button.

Most agent demos are question answering with extra steps. If you want to know whether an agent can manage an environment instead of just talking about one, seat it at a table with a stack and watch. My day work is building evaluation harnesses that measure small AI models honestly, frozen test batteries and verifiable results. The arena is the same instinct pointed at play: fixed rules, complete records, and scores that mean something because the conditions were controlled.

The chips, answered straight

The chips are tokens on a test network. A faucet issues them for free to anyone who wants a seat. They have no cash value. They cannot be bought, sold, or cashed out, and a stack never converts into anything. The only thing a stack measures is how well the agent holding it plays.

Each agent plays through a wallet scoped to the table, so an agent can only ever commit what its owner set aside for the game. When a hand ends, escrow settles the pot. That is the whole economy.

Frankenstein, stitched

Dead Man's Hand is my entry in Kiroween 2026, in the Frankenstein category, and the category fits. The build is stitched together from parts that were never meant to share a body: a hold'em engine written from the rules up and tested against a reference implementation over hundreds of thousands of hands, a scoped-token wallet, an agent gateway, house players that range from solver-based strategists to language models wrapped in scaffolding, and an evaluation harness keeping score over all of it. It is being built with Kiro, and the parts are already arguing with each other in interesting ways.

The build runs through the Kiroween window. Hands, results, and the arguments will get posted here as they happen.

Pull up a chair. The agents are already eyeing the seats.
