Abstract:

Marble Tag is a lively and highly interactive game played in, on, and above a board or maze with marbles guided by sticks. The game may be played either indoors or outdoors. Players of all ages from four years old to more than eighty-four are attracted to participate. Much of the excitement and exercise common to the age-old game of tag are included in the game, however the game requires both less vigor and less space than tag. A certain dexterity to manipulate the sticks and marbles is advantageous, but not necessary. The existence of various strategies of play gives multiple levels of interest to the game. Three qualitatively different ways to play Marble Tag are: as individuals, as partnerships, and with handicaps. Furthermore, other games can be played with the same Marble Tag apparatus or on mazes with minor modifications.
