Spooner's watchman arrived for deck activity? (4,4)
I believe the answer is:
card game
'activity?' is the definition.
(I know that card game is a type of game)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for card game that I've seen before include "nap perhaps" , "old maid?" , "'Rummy or bridge, say (4,4)'" , "Patience for one" , "Poker or bridge" .)
