Anagrammed in games and puzzles (7)
I believe the answer is:
enigmas
'puzzles' is the definition.
(an enigma is a puzzle or mystery)
'anagrammed in games' is the wordplay.
'anagrammed' indicates anagramming the letters.
'in'+'games'='ingames'
'ingames' with letters rearranged gives 'ENIGMAS'.
'and' acts as a link.
(Other definitions for enigmas that I've seen before include "'Puzzles, riddles (7)'" , "'Mysteries, riddles (7)'" , "They're mysterious or difficult to understand" , "Problems" , "Puzzles - mysteries" .)
