Game on the snooker table? (3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
nap
'game' is the definition.
(card game)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nap that I've seen before include "Pile (on e.g. velvet)" , "One likely to win" , "A daytime doze" , "Take forty winks" , "A brief snooze" .)
