Waiting game? (5)

I believe the answer is:

ready

I believe this is a double definition.

'waiting' is the first definition.
(thesaurus)

'game?' is the second definition.
(thesaurus)

(Other definitions for ready that I've seen before include "Willing (to do something), prepare" , "Prepare money" , "bread" , "Prepared, willing" , "Available now" .)

I've seen this clue in The Telegraph.
