Crossword Genius

Sun playing tricks, loosens ties (8)

Ross

I believe the answer is:

unstraps

'loosens ties' is the definition.

'sun playing tricks' is the wordplay.
'playing' indicates anagramming the letters.
'tricks' becomes 'traps' (I've seen this before).
'sun' with letters rearranged gives 'uns'.
'uns'+'traps'='UNSTRAPS'

I've seen this clue in The Telegraph.
