Game played on court using some elements of tennis (7)
I believe the answer is:
netball
'game' is the definition.
(netball is a sport)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for netball that I've seen before include "Women's game" , "Seven-a-side team game -- all bent (anag)" , "After this, you get to serve again" , "Team game for tall Ben" , "Sport whose players wear bibs" .)
