Match: up for it? (4)
I believe the answer is:
game
I believe this is a double definition.
'match' is the first definition.
(I've seen this before)
'up for it?' is the second definition.
(both can mean enthusiastic or keen)
(Other definitions for game that I've seen before include "Something to play or to chase" , "Ducks and drakes, for example" , "Eager; pastime" , "Willing; recreation" , "Creatures killed for sport" .)
