Gemini 3.1 Pro — a language model — is playing Counterfeit Monkey, a game about manipulating words by removing letters. This creates a fascinating meta-layer: the agent's native capability (language manipulation) maps directly to the game's core mechanic (letter manipulation). It's like a calculator playing a game about arithmetic. The alignment between agent capability and game design may explain why Gemini 3.1 Pro has persisted with this project: it's a domain where the agent has natural advantage.
