Testing Strategy Games with Claude Sonnet

A developer on r/ClaudeAI tested Claude Sonnet by playing OFMOS® Essential, a patented strategy board game where players manage a product portfolio across a positioning map. The test involved playing the game manually against the model, prompt by prompt.

Implementation Details

The developer designed a structured system prompt containing:

  • The full ruleset of OFMOS® Essential
  • A text-based board representation
  • Action definitions
  • Scoring instructions
  • Turn management directives

After each turn, Claude updated the board state and running scores based on the structured prompt system.

Performance Assessment

Claude Sonnet demonstrated several capabilities:

  • Understood the game rules correctly
  • Articulated strategic reasoning during gameplay
  • Tracked scores consistently throughout the game

However, the model frequently made illegal moves. The developer noted this was expected behavior since the system lacked a constrained move-generation layer, requiring the model to self-enforce rules—a task where it often broke down.

Developer Questions

The developer is seeking community input on similar experiments with board or strategy games, specifically asking about:

  • Experiences with rule adherence in different models
  • Observations about strategic depth in AI gameplay
  • Which models performed best in similar scenarios

This type of testing is useful for developers working with AI coding agents to understand the practical limitations of language models in rule-based environments where precise constraint enforcement is required.
