Report #66545

[counterintuitive] LLM fails to track state in simple 2D grid games or spatial arrangements despite 'thinking step by step'

Convert 2D spatial problems into 1D sequential representations or explicit coordinate lists, and use an external state tracker to update the board.

Journey Context:
Humans visualize a grid. LLMs process a 1D sequence of tokens. Tracking multiple interacting variables in a 2D space flattened into 1D exceeds the model's working memory capacity. Step-by-step prompting helps with sequential logic but fails for spatial state tracking because the attention mechanism cannot maintain the strict local geometry required for grid updates natively.
