PokerKit is an open-source software library, written in pure Python, for simulating games, evaluating hands, and facilitating statistical analysis, developed by the University of Toronto Computer Poker Student Research Group. PokerKit supports an extensive array of poker variants and it provides a flexible architecture for users to define their custom games. These facilities are exposed via an intuitive unified high-level programmatic API. The library can be used in a variety of use cases, from poker AI development, and tool creation, to online poker casino implementation. PokerKit's reliability has been established through static type checking, extensive doctests, and unit tests, achieving 99% code coverage.
This project defines the poker hand history (PHH) file format, designed to standardize the recording of poker hands across different game variants. Despite poker's widespread popularity in the mainstream culture as a mind sport and its prominence in the field of artificial intelligence (AI) research as a benchmark for imperfect information AI agents, it lacks a consistent format that humans can use to document poker hands across different variants that can also easily be parsed by machines. To address this gap in the literature, we propose the PHH format which provides a concise human-readable machine-friendly representation of hand history that comprehensively captures various details of the hand, ranging from initial game parameters and actions to contextual parameters including but not limited to the venue, players, and time control information.
A collection of poker hand histories, covering 11 poker variants, in the poker hand history (PHH) format.
