Claim:
A method for playing a race game, comprising: designating a starting line, a finishing line, and a set of physical game play boundaries between the starting line and the finishing line; outfitting each of at least two runners with a locator device, wherein the at least two runners include one or more runners of a first type and one or more runners of a second type, and wherein the locator device is configured to determine its physical location within the set of physical game play boundaries between the starting line and the finishing line; for each of the one or more runners of the first type or of the second type, accruing, by at least one processor, a first predetermined number of points for covering a predetermined distance within the set of physical game play boundaries between the starting line and the finishing line, the predetermined distance determined by the locator device; and depleting, by the at least one processor, a second predetermined number of points from a first runner of the first type or of the second type when tagged by a second runner of the first type or a third runner of the second type, wherein the first runner is tagged by the second runner or the third runner based on: (i) a proximity between the first runner and the second runner or the third runner, determined by the locator devices of the first runner and the second runner or the third runner, without the second runner or the third runner physically contacting the first runner, and (ii) a rate of change in at least one of a velocity and a direction of the second or third runners toward the first runner being greater than a respective rate of change in velocity and direction of the first runner in proximity to the second or third runners.
