Cleans up at games of chance (6)
I believe the answer is:
sweeps
'cleans up' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for sweeps that I've seen before include "Cleans with a broom" , "Clean with a broom" , "Moves in an arc" , "Cleans the floor with a brush" , "Old blackguards" .)
