Everyone bent round - first game (7)
I believe the answer is:
netball
'game' is the definition.
(netball is a kind of game)
'everyone bent round first' is the wordplay.
'everyone' becomes 'all' (I've seen this before).
'round' is an anagram indicator.
'first' means one lot of letters go next to another.
'bent' anagrammed gives 'netb'.
'all' put after 'netb' is 'NETBALL'.
(Other definitions for netball that I've seen before include "Team sport" , "Seven-a-side team game -- all bent (anag)" , "Sport whose players wear bibs" , "Team game, played mainly by women" , "After this, you get to serve again" .)
