Chuck to leave for game (5)
I believe the answer is:
bingo
'game' is the definition.
(bingo is a kind of game)
'chuck to leave' is the wordplay.
'chuck' becomes 'bin' ('bin' can be used as a verb).
'to' is a charade indicator (letters next to each other).
'leave' becomes 'go'.
'bin'+'go'='BINGO'
'for' acts as a link.
(Other definitions for bingo that I've seen before include "Cry on discovering something" , "Game in which "two little ducks" might be called" , "Lotto" , "Popular gambling game in which numbers are called at random" , "House!" .)
