Splendor is a card-based strategy game where players collect gems to purchase development cards and attract noble patrons. The Trace Studio implementation includes a high-performance engine written for fast simulation, along with multiple AI solvers.

Engine

The engine supports full game rules for 2–4 players, with an optimized state representation for efficient tree search.

Solvers

• Heuristic: Greedy gem-collection and card-purchasing strategy.
• RL: Self-play PPO agent trained over 10M episodes.
• LLM: GPT-4 and Claude-based agents with structured prompting.

Results

The RL agent achieves a 72% win rate against the heuristic baseline in 2-player games.
