A situation where one postpones or delays a decision or course of action so as to first see what might happen or what one's opponent(s) might do. (Often used in the phrase "play a/the waiting game.") The prosecution has submitted a plea bargain to the defendant, so it's a bit of a waiting game at the moment to see if she will take it.The market is rather tumultuous at the moment, so I think we're better off playing the waiting game rather than making any hasty decisions.
