Game bird returned to new home (8)
I believe the answer is:
ninepins
'game' is the definition.
(ninepins is a kind of game)
'bird returned to new home' is the wordplay.
'bird' becomes 'snipe' (snipe is a kind of bird).
'returned' says the letters should be written in reverse.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'home' becomes 'in' ('he's home' can mean 'he's in').
'snipe' back-to-front is 'epins'.
'n'+'in'='nin'
'epins' after 'nin' is 'NINEPINS'.
(Other definitions for ninepins that I've seen before include "Form of skittles" , "Bowling game" , "Skittles (IX, not V)" , "Bowling targets" , "Skittles, IX objects to be knocked down" .)
