ThreePlayerGOPS

Description

ThreePlayerGOPS is an environment for evaluating agents on strategic card play in the Game of Pure Strategy. This environment wraps the ThreePlayerGOPS implementation from TextArena, a framework for text-based game environments.

Capabilities

• Strategic card value assessment
• Anticipating opponent behavior
• Resource management across multiple rounds
• Simultaneous bidding and tie-breaking strategies

Compute Requirements

ThreePlayerGOPS does not require a sandbox. It has minimal compute requirements.

License

MIT.

Tasks

There are two splits: train (150 tasks) and test (150 tasks). Each split contains 50 tasks across each of 3 variants:

• ThreePlayerGOPS-v0
• ThreePlayerGOPS-v0-train
• ThreePlayerGOPS-v0-raw

Each task is seeded for reproducibility.

Reward Structure

This is a sparse reward environment. Rewards are mapped from TextArena's native range of {-1, 0, 1} to {0.0, 0.5, 1.0} via (raw + 1) / 2.

We do not use LLM graders for this environment; reward is determined programmatically.

Data

Game state is generated procedurally by the TextArena engine using seeded randomness. No external data files are required.

Tools

Agents are given a single tool:

• play_card(card): Play a card from your hand. Use values like 'A', '2', '3', ..., '10', 'J', 'Q', 'K'.

Time Horizon

ThreePlayerGOPS is a multi-turn environment.

Environment Difficulty

Medium. Agents must balance immediate gains against future opportunities and anticipate opponent strategies in a simultaneous-play setting with 13 rounds.

Other Environment Requirements

This environment requires an OpenAI API key (passed via secrets) to power the LLM opponents.

Safety

Agents in ThreePlayerGOPS interact only with a strategic card game and have no access to external systems, the internet, or sensitive data. The environment does not present safety risks.
