What is OpenHoldem?

(Poker Bot)

OpenHoldem (along with its supporting applications: OpenScrape, ManualMode, and OHReplay) is an open-source screen scraping framework and programmable logic engine designed for online Texas Hold’em poker games. This framework allows you to create your own Texas Hold’em poker robot (bot) that automatically analyzes the game and makes decisions.

Any poker bot consists of two main components:

• Game State Engine: Determines the current game situation.
• Action Engine: Decides and executes poker actions (fold, call, raise, etc.).

How Does OpenHoldem Determine the Game State?

OpenHoldem uses the screen scraping method – it analyzes the pixels on the poker client’s screen to identify the game state (cards, bets, pot size, player actions, etc.). Unlike other methods (such as reading memory or code injection), screen scraping is safer and more universal, as it works with any poker client without interfering with its code.

Screen scraping is a classic approach that has been used for decades to solve various automation tasks.

Action Engine (Autoplayer)

The Autoplayer uses logic defined by you to decide what action to take based on the current game state. After making a decision, it automatically clicks buttons or enters text in the poker client window, simulating human actions.

OpenHoldem as a Framework

OpenHoldem is not a ready-to-use “plug-and-play” bot – it is a flexible tool that requires configuration:

1. Table maps (using OpenScrape): Parameters that specify how to interpret the screen pixels for a specific poker room (casino). Each poker site needs its own configuration.
2. Game logic: You define how the bot should play (aggressive, conservative, etc.) using formulas, scripts, or DLL extensions.

Supported Poker Rooms and Variants

OpenHoldem supports all existing online poker rooms and all Texas Hold’em variants:

• No-Limit, Fixed-Limit, Pot-Limit
• Full Ring, 6-Max, Heads-Up
• Tournaments: MTT, SNG, Double or Nothing, Turbo, etc.

If a room doesn’t work, the community and developers quickly respond to changes.

OpenHoldem is an ideal solution for poker enthusiasts and developers who want to build custom poker bots. It is a free, community-maintained project with an active forum and continuous improvements.

Warning: Using poker bots is prohibited in most online poker rooms and can lead to account bans. Use responsibly, for example, for research or private purposes.
