In Case 7 - Solomon, this is the final puzzle with Solomon hanging from a cart above some gas pipes. The first stage is a single push to the second stage but be sure to grab the puzzle piece to the left in the tunnel before pushing him through. The second stage is another cart moving puzzle like the rest in the game where you must move carts to clear a path to push him through. The third stage is the big pain. You will need to solve a TV memory match puzzle to open the door and free him. Just remember that you are matching two related pictures this time, not two of the same. For instance, shotgun shells match the shotgun, film roll matches the camera. All through this puzzle you will be moving him from one burner to the next when they ignite. Don't worry, your matches stay equipped when you back out of the TV game to move him.
