RLCard is an open-source toolkit for reinforcement learning research in card games. It supports various card environments with easy-to-use interfaces, including Blackjack, Leduc Hold'em, Texas Hold'em, UNO, Dou Dizhu and Mahjong. The goal of RLCard is to bridge reinforcement learning and imperfect information games, and push forward the research of reinforcement learning in domains with multiple agents, large state and action space, and sparse reward. In this paper, we provide an overview of the key components in RLCard, a discussion of the design principles, a brief introduction of the interfaces, and comprehensive evaluations of the environments. The codes and documents are available at https://github.com/datamllab/rlcard

  1. LLMs as Agentic Cooperative Players in Multiplayer UNO

    cs.AI 2025-09 conditional novelty 6.0 of 10

    LLMs can beat random agents in UNO, but as cooperative partners only LLaMA3.3-70B with cloze prompting gave a significant teammate win-rate gain (35.00% to 35.96%).

  2. Cardiverse: Harnessing LLMs for Novel Card Game Prototyping

    cs.CL 2025-02 conditional novelty 6.0 of 10

    An LLM-based pipeline generates novel card game variants, validates their code using gameplay records, and builds competitive AI agents from ensembles of LLM-written scoring functions.

  3. Analysis of Bluffing by DQN and CFR in Leduc Hold'em Poker

    cs.AI 2025-09 conditional novelty 4.0 of 10

    In a 100,000-game comparison, both DQN and CFR agents raised with weak hands (bluffed) at different rates but with roughly similar success rates.
