[counterintuitive] Model fails to solve Sudoku or navigate 2D grids/mazes despite clear rules

Convert spatial or grid problems into graph searches or constraint satisfaction problems, and write code to solve them. Do not ask the LLM to solve them directly in text.

Journey Context:
Text is a 1D sequence, but spatial problems require 2D or 3D representations. LLMs flatten these into 1D token streams, losing structural adjacency. Solving Sudoku requires backtracking and constraint propagation—search algorithms—which autoregressive text generation cannot perform reliably because it cannot 'undo' a generated token. Writing a solver script bridges this gap.
