Game never ends - it's a farce (7)
I believe the answer is:
charade
'a farce' is the definition.
(both can mean absurd or false situation)
'game never ends' is the wordplay.
'game' becomes 'charades' (charades is a kind of game).
'never ends' means to remove the last letter (I've seen 'never ending' mean this).
'charades' with its last letter removed is 'CHARADE'.
'it's' acts as a link.
(Other definitions for charade that I've seen before include "Game in which the answer is acted out" , "Absurd pretence to create a good impression" , "Travesty, mockery" , "An absurd pretence, could be a game" , "Farce - mime" .)
