> A multiple-choice visual reasoning benchmark built on 🌀 **maze** navigation and 📦 **Sokoban** puzzles. Each sample provides an initial-state image, an optimal-solution video, and a question about the planned trajectory.

## 🏷️ Categories

| Category | Task | Description |
|----------|------|-------------|
| `C1_turn_count`      | 🌀 maze    | Total number of direction changes along the path |
| `C2_turn_direction`  | 🌀 maze    | Number of LEFT / RIGHT turns |
| `C4_sokoban_push`    | 📦 sokoban | Direction of a specific push |
| `C5_direction_count` | 🌀 maze    | Number of steps in a given direction |
| `C6_push_dir_count`  | 📦 sokoban | Number of pushes in a given direction |
