Describe spherical object in war game (9)
I believe the answer is:
paintball
'war game' is the definition.
(I've seen this before)
'describe spherical object' is the wordplay.
'describe' becomes 'paint' (I've seen this before).
'spherical object' becomes 'ball' (I've seen this before).
'paint'+'ball'='PAINTBALL'
'in' acts as a link.
(Other definitions for paintball that I've seen before include "war game" , "messy game" , "simulated combat" , "Missile used in war games" .)
