With nothing on television, you played Solitaire in the end (4)
I believe the answer is:
nude
'with nothing on' is the definition.
(without clothes on)
'television you played solitaire in the end' is the wordplay.
'in the end' indicates one should take the final letters.
The last letters of 'television you played solitaire' are 'NUDE'.
(Other definitions for nude that I've seen before include "rejecting coverage?" , "Naked art subject" , "Appearing as nature intended?" , "Naked, bare" , "Classic art subject" .)
