it's 4 gl8rious !

Welcome to the forum. I won as intended by pushing all the balls and that wasn't too hard. I also won by pushing only 3 balls - see picture

Spoiler: Picture

I pushed the free draggable thru one ball and two others fell. I then pushed B up onto the stairs and B when to the win. I also won without B too. How? Slide the free draggable up the wedges where B starts onto the lift, raise the lift and toss the free draggable higher and drag it over to the win and drop it. We don't recommend using free draggables, always anchor them with a slider otherwise we can win too easily.

Welcome to the forum

But you don't have to use free draggable bcz we can take draggable anywhere and then the gameplay goes waste
