Advantage Play & Game Integrity

Poker bot AI

A poker bot AI is software that uses artificial intelligence to make betting decisions and play poker automatically against human or computer opponents, most commonly in Texas hold'em.

Also called
pokerbot, bot, computer poker player3
Applies to
Texas hold'em, especially heads-up no-limit and multiplayer no-limit4
Key method
Counterfactual regret minimization (CFR) and self-play/search2
Notable bots
DeepStack (heads-up), Pluribus (multiplayer)5

Key points

  • Poker bot AIs use game-theoretic methods such as counterfactual regret minimization to choose actions under incomplete information.2
  • Some bots aim for near-optimal, hard-to-exploit play; others are designed to be exploitative against human weaknesses.1
  • Online poker rooms normally prohibit poker bots, and using one can result in account closure and forfeiture of funds.6
  • Notable examples include DeepStack, which beat professional humans in heads-up no-limit Texas hold'em, and Pluribus, which achieved superhuman performance in six-player no-limit.45

How a poker bot AI works

  1. The bot receives the current game state: cards, bets, position, and opponent actions.
  2. It evaluates possible actions using algorithms like counterfactual regret minimization, which simulates many hands to find near-optimal strategies under incomplete information.2
  3. The bot selects an action (fold, call, raise) and sends it to the poker client, often faster than a human could react.
