Card game with tricks finally played (5)
I believe the answer is:
whist
'card game' is the definition.
(whist is a kind of card game)
'with tricks finally played' is the wordplay.
'finally' says to take the final letters.
'played' indicates an anagram (letters playing around).
The last letter of 'tricks' is 's'.
'with'+'s'='withs'
'withs' with letters rearranged gives 'WHIST'.
(Other definitions for whist that I've seen before include "18th-century card game, the forerunner of bridge" , "Card-game" , "calls for silence?" , "Popular card game, sometimes solo" , "Tricky card game" .)
