Conclusion in home game (5)
I believe the answer is:
omega
'conclusion' is the definition.
(omega is a kind of conclusion)
'in home game' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OMEGA' can be found hidden inside 'home game'.
(Other definitions for omega that I've seen before include "in Greece, the limit!" , "symbol of resistance?" , "The last in a series of letters" , "Final Greek letter" , "Conclusion" .)
