Reward Tom perhaps, for waiting game (6)
I believe the answer is:
tipcat
'waiting game' is the definition.
'tipcat' can be an answer for 'game' (I've seen this before). I am not certain of the 'waiting' bit.
'reward tom perhaps' is the wordplay.
'reward' becomes 'tip' (I have seen 'tiny reward' mean 'tip' so perhaps 'reward' could also mean 'tip').
'tom perhaps' becomes 'cat' (a tom is a male cat).
'tip'+'cat'='TIPCAT'
'for' is the link.
Can you help me to learn more?
(Other definitions for tipcat that I've seen before include "Game" , "Hint" .)
