[counterintuitive] LLMs can play Tic-Tac-Toe or Chess natively if given enough examples in the prompt

Convert spatial/grid states into text-based representations processed by external engines, or use specialized models; do not ask standard LLMs to track 2D spatial grids natively.

Journey Context:
Humans visualize a tic-tac-toe board spatially. LLMs process it as a 1D sequence of tokens \(e.g., 'X O \_ \_ X \_ \_ \_ O'\). Tracking spatial relationships \(diagonals, adjacencies\) in a 1D token stream requires maintaining a complex, multi-step spatial transformation in latent space. As the game progresses, the model loses track of the board state because it lacks a spatial world model. It cannot 'see' the board.
