A game of many skills (5)
I believe the answer is:
darts
'a game' is the definition.
(darts is a kind of game)
'many skills' is the wordplay.
'many' becomes 'd' (**).
'skills' becomes 'arts' (I've seen this before).
'd'+'arts'='DARTS'
'of' is the link.
(Other definitions for darts that I've seen before include "They are thrown at targets in pubs" , "Game; moves quickly" , "Game with board and missiles" , "Game with arrows and a board" , "Tears" .)
