Played pool or another game (4)
I believe the answer is:
polo
'another game' is the definition.
'polo' can be an answer for 'game' (polo is a kind of game). I am not sure about the 'another' bit.
'played pool' is the wordplay.
'played' indicates an anagram.
'pool' with letters rearranged gives 'POLO'.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for polo that I've seen before include "Game played on horses or in water" , "Ball game played on horseback" , "In which horsemen attack and defend" , "Game; Venetian explorer" , "Top" .)
