Corner pieces are always obvious. Hard puzzle has teal edge pieces connected to the top right corner piece which makes them easy.
Also good to know is that tiles will flip with another tile only once, so if you don't fuck the pieces up early on, you will know where most pieces go because they'll have swapper with another tile near the end.
Hopefully all of this makes sense to you. Try to get some decent sized Pokemon, it really helps.
