Is one of the rules that you have to use all the puzzle pieces? Because puzzle #3 is easily solved with only two pieces yet that is not the "correct" solution.

Kind of a good analogy for Google in the 2020s, isn't it?

Getting WASD and Space instructions on mobile too...

Unfortunately yes, you have to use every single piece.

And that's not explicitly stated.

Had the same "problem" too. I would expect better from an adtech/software firm.

Yes.
