How the AI Works

The AI uses the Expectimax algorithm, a variant of minimax designed for games with randomness. It searches 3-5 moves ahead depending on board complexity.

The evaluation function scores boards using a snake-weighted pattern that keeps high tiles in the corner, plus bonuses for empty cells and monotonic rows.

Search depth adapts dynamically: fewer empty cells triggers deeper search for more accurate play in critical positions.
