Game Venetian who travelled widely in the East (4)
I believe the answer is:
polo
This clue is a double definition.
'game' is the first definition.
(polo is a kind of game)
'venetian who travelled widely in the east' is the second definition.
(explorer Marco Polo)
(Other definitions for polo that I've seen before include "Top" , "Pool (anag.)" , "Game; Venetian explorer" , "It's played in water and on horseback" , "Equestrian sport" .)
