Rush Hour 6×6 — All Entries (0/1/2 Walls)
Derived from Michael Fogleman’s full 6×6 database. See: https://www.michaelfogleman.com/rush/
Columns
- board: 36-char row-major; 'o' empty, 'x' wall (fixed), 'A' primary car, 'B..Z' others (len 2 or 3)
- moves: minimal #moves (a move = slide any distance along piece axis)
- cluster_size: states in the cluster (from source)
- num_walls / has_walls: wall metadata
- task: "moves" or "solve"
- solution: optimal move list (when --task solve and found)
- messages: chat format ready for SFT (Qwen, etc.)
Notes
- This dataset intentionally includes 0-, 1-, and 2-wall puzzles from the official file.
- For sequence supervision, use --task solve (heavy for 6×6; prefer --limit).
