A game timer for selectively timing the action time of two or more game players includes a timing unit for each player with the timing unit consisting of a reservoir containing a measured quantity of granular medium with a metered orifice for controlling the flow of the granular medium from the reservoir upon selected specific orientations for each separate reservoir. Each reservoir is oriented for a separate active and deactive orientation such that when one reservoir is actively timing, the other reservoir is inactive.
