I believe the answer is:

throw for a loop

I'm a little stuck... Click here to teach me more about this clue!

'boomerang puzzle?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'play' is the wordplay.
I cannot quite see how this works, but
'play' could be 'throw' (throw is a kind of play) and 'throw' is located in the answer.
This explanation may well be incorrect...

'with' is the link.

Can you help me to learn more?
