Foul udon eaten as pastime (4)
I believe the answer is:
ludo
'pastime' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'foul udon eaten' is the wordplay.
'eaten' indicates the answer is hidden within the clue.
'LUDO' can be found hidden inside 'foul udon'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for ludo that I've seen before include "Traditional board game" , "Race game" , "Simple board game, involving dice" , "Children's board game" , "Type of board game" .)
