I believe the answer is:

waterloo

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

'final defeat' is the definition.
(I've seen this before)

'a pool game possibly?' is the wordplay.
I cannot quite understand how this works, but
'a' is present in the answer.
'game' could be 'loo' (historic card game found in Jane Austen novels) and 'loo' is present in the answer.
This explanation may well be incorrect...

'in' acts as a link.

Can you help me to learn more?

(Other definitions for waterloo that I've seen before include "Decisive defeat" , "Losers may meet theirs" , "Napoleon's final battle" , "Final challenge" , "Signal failure for French" .)

I've seen this clue in the Evening Standard.
