Complains about game point? (7)

I believe the answer is:

grouses

'complains' is the definition.
(grousing is a kind of complaining)

'game point?' is the wordplay.
'game' becomes 'grouse' (I've seen this before).
'point?' becomes 'S' (S is an example).
'grouse'+'s'='GROUSES'

'about' is the link.

(Another definition for grouses that I've seen is " Complains".)

I've seen this clue in The Globe and Mail.
