Testing Claude Sonnet with a Strategy Board Game: Rule Adherence Challenges
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.
