A multiple-choice visual reasoning benchmark built on π maze navigation and π¦ Sokoban puzzles. Each sample provides an initial-state image, an optimal-solution video, and a question about the planned trajectory.
| Category | Task | Description |
|---|---|---|
C1_turn_count |
π maze | Total number of direction changes along the path |
C2_turn_direction |
π maze | Number of LEFT / RIGHT turns |
C4_sokoban_push |
π¦ sokoban | Direction of a specific push |
C5_direction_count |
π maze | Number of steps in a given direction |
C6_push_dir_count |
π¦ sokoban | Number of pushes in a given direction |
question, options (AβD), answer (correct key), correct_value, task_type, input_image / video_path (relative to each split dir), _solution (ground-truth solution trace).
