A simple puzzle played on the old Merlin handheld game units. The playing field is nine boxes in three rows of three, like a tic-tac-toe board. The game begins with small LED lights blinking in several of the nine spaces. The object is to create a "magic square" or ring, leaving the center box dark. This is done by observing the light patterns triggered when pressing each of the nine spaces. Find a correct sequence and voila - you've made a Magic Square!
