Sets kilt out for game (8)
I believe the answer is:
skittles
'game' is the definition.
(skittles is a kind of game)
'sets kilt out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'sets'+'kilt'='setskilt'
'setskilt' is an anagram of 'SKITTLES'.
'for' acts as a link.
(Other definitions for skittles that I've seen before include "Ninepins" , "bowling pursuit" , "Bowling game" , "Game in which ball is aimed at pins" , "Pub game" .)
