Moments after tight game (11)
I believe the answer is:
tiddlywinks
'game' is the definition.
(tiddlywinks is a kind of game)
'moments after tight' is the wordplay.
'moments' becomes 'winks'.
'after' means one lot of letters go next to another.
'tight' becomes 'tiddly' (synonyms).
'winks' after 'tiddly' is 'TIDDLYWINKS'.
(Other definitions for tiddlywinks that I've seen before include "Counter-flipping game" , "Children's game" , "Game of flicking counters" , "Game of flipping counters" , "Game of flicking disks" .)
